This document summarizes different methods used to increase the productivity of solar stills for distilling water. It describes the basic components and functioning of common solar still designs like box, cone, and pit stills. It then reviews several active methods researchers have used to augment solar still productivity, such as integrating the still with solar collectors, mini solar ponds, fins, sponges or baffles. One study found productivity increased up to 120% when combining a single slope still with a solar water heater. Another found productivity increased 370% using two water heaters in a double slope still. The highest productivity of 100% was obtained with a fin-type still integrated with pebbles and sponges.
This document describes the design of a solar distillation system to purify water. It discusses how solar energy can be used as a renewable energy source to power a simple distillation process. A solar still was constructed using a blackened galvanized iron sheet as the basin, thermocol and wood composite walls for insulation, and a glass top. Through evaporating dirty water using solar heating and condensing the vapor on the glass top, the system is able to produce 1.5 liters of purified water from 14 liters of dirty water over six hours, with an efficiency of 64.37% and total dissolved solids of 81ppm in the purified water.
The document describes the operation and components of a small-scale solar still for distilling water. A solar still uses sunlight to heat water in a shallow basin, causing evaporation. Vapors condense on the glass cover and drain as distilled water. Key components are the basin, glass cover, and distillate collection trough. With a daily solar irradiation of 18 MJ/m2, a simple basin still can produce around 2.3 liters of distilled water per square meter of aperture area. The still works best when the basin water is shallow and hot compared to the condensing surface.
The water and the energy are the two most essential things for the sustaining of life. Only less the 1% water is available for the society for direct use, out of which the maximum fraction has been polluted due to non-manageable industrial developments. A solar still is a device which can solve the problem of potable water without using the high grade energy .An overview has been given in this paper of introduction to solar still with a view to explain the principle and the mechanism of operation.
There are many types of solar still, including large scale concentrated solar stills and condensation traps (better known as moisture traps amongst survivalists). In a solar still, impure water is contained outside the collector, where it is evaporated by sunlight shining through clear plastic or glass. The pure water vapor condenses on the cool inside surface and drips down, where it is collected and removed.
Distillation replicates the way nature makes rain. The sun's energy heats water to the point of evaporation. As the water evaporates, water vapor rises, condensing into water again as it cools and can then be collected. This process leaves behind impurities, such as salts and heavy metals, and eliminates microbiological organisms. The end result is pure distilled water.

Solar Water Distillation and PurificationHassan Raza
This document describes a solar water distillation and purification system designed by a group of students. The system uses solar energy to evaporate water which then condenses on the inside of a glass surface, purifying it in the process. The students coated the interior with black silicon to maximize heat absorption. They determined thin glass works better than thick for condensation. The system produces around 4 liters of water per day from a 2 by 4 foot panel, and efficiency could be increased by enlarging the panel or adding a parabolic trough deflector. The design uses inexpensive, locally available materials and could provide clean drinking water for remote areas lacking access.
This document presents a summary of a student's research project on solar stills. It introduces solar stills as a method for purifying saline water using solar energy. It provides a brief history of solar stills, describes how they work through evaporation and condensation, and compares different types. The student's research is summarized as testing three solar still models with different water levels to determine maximum productivity. The conclusion is that less water in the still basin leads to higher efficiency. Solar stills provide an economical way to obtain drinking water in locations without other sources.

This document summarizes an experimental study on augmenting fresh water production from a triangular pyramid solar still by using a phase change material (PCM). The study aims to improve the low productivity of conventional solar stills. Experiments are conducted with and without a PCM to compare the distillate output and other parameters. Results show that using a PCM increased the daily water production to 4.3 liters compared to 3.5 liters without PCM. Temperature differences between the glass and water are also reduced with the PCM. The maximum solar still efficiency reached 35.2% without PCM and 53% with PCM. The study concludes that incorporating a PCM is effective for improving solar still productivity.

Ground water distillation by basin type solar still for different basin water...IJERA Editor
Adequate quality and reliability of drinking water supply is a fundamental need. Without potable water or
drinking water (less than about 500 ppm of salt) human life is not possible. Only 1% of Earth's water is in a
fresh, liquid state, and nearly all of this is polluted by both diseases and toxic chemicals. For this reason,
purification of water supplies is extremely important.
Keeping these things in mind, we have devised a model which will convert the saline ground water into pure
and potable water using the renewable source of energy (i.e. solar energy). Solar energy is an abundant, never
lasting, and available on site and pollution free energy.Solar Energy is freely available and can be used as a very
cheap option to convert saline ground Water through Solar Distillation, by using Solar Stills. The conventional
single basin and single slop Passive Solar Still can be used to purify water but the main problem is that the per
square meter distillate output is less. So it is need to modify the design of solar still for high output of solar
distillate
Solar still is easy to construct, can be done by local people from locally available materials, simple in
operation by unskilled Personnel, no hard maintenance requirements and almost no operation cost. Simplest
basin type models of solar still in earlier days, researchers have progressed a lot to increase its efficiency.
Suitable modification of solar still can produce high output using minimum areas of land and even in cloudy
days. Experimental study is done at Rewa M.P. on two different basin water depth solar stills. Low water depth
solar water still is produced more distillate than high water depth still by the experiment.
The document is a project report on solar distillation presented by students of the chemical engineering department. It includes an introduction to solar distillation, the history of the technique, different types of solar stills, the theory and construction of solar stills, their use in water purification, advantages and disadvantages compared to other methods. The report concludes that solar distillation provides a sustainable means of desalination and fresh water production using renewable solar energy with minimal environmental impact.
A solar still is a simple device that uses solar energy to distill and purify water. It has two main types - box and pit stills. Water is evaporated by sunlight and the vapor condenses on the inside surface, then drips down into a collection area. The process removes impurities through evaporation and condensation, producing cleaner water than rainwater. Solar stills have advantages of being low-cost using free solar energy, but also have disadvantages like low production capacity and not killing all bacteria. They can be used to provide clean water for drinking or industrial processes.
The document discusses solar water distillation as a method for purifying water. It begins by noting that over 1 billion people lack access to clean drinking water. It then explains that solar distillation works by evaporating water using sunlight, with the vapor condensing as pure water. Key factors that affect evaporation rates are identified. Applications of solar distillation include use in industries, hospitals, laboratories, and for obtaining fresh water in coastal or marshy areas. Advantages include not requiring fuel, being scalable locally, and ability to purify saline water. Disadvantages include lower production capacity and dependence on weather. The conclusion discusses designing a scalable dual stage system for physical and UV purification of water to help those without access to
This document presents information on solar thermal desalination. It introduces different desalination techniques such as multi-stage flash desalination, multi-effect desalination, reverse osmosis, and forward osmosis. Multi-stage flash desalination produces about 60% of desalinated water worldwide by flashing sea water into steam in multiple heat exchangers. Multi-effect desalination uses multiple effects where steam heats and evaporates water in successive stages. Reverse osmosis uses the natural process of osmosis to move solvent from a lower concentration to a higher concentration area. Solar desalination has advantages as the solar energy source is free, making water production affordable, and it is an eco

This document describes the design and principles of operation of a solar still for purifying water. It discusses various types of solar stills including pit, box, concentrating collector, multiple tray, tilted wick, and their components and functioning. It explains that solar stills use the sun's energy to evaporate dirty water through a process of heating, evaporation, condensation and collection of purified water. They are useful for providing clean drinking water in remote areas without access to treated water supplies. The document outlines the scope of the project to study the efficiency of a solar still and analyze converting a solar cooker design to a solar still.
The document discusses using solar power to provide energy for desalination systems. It notes that 97% of the world's water is salt water, while only 3% is freshwater. It proposes investigating whether current desalination methods could be powered by photovoltaic cells to provide fresh drinking water in a sustainable way. Key questions examined are the energy requirements of different desalination techniques and how those requirements compare to the power output of solar arrays.
This document discusses solar desalination technologies. It begins by introducing conventional desalination methods like multi-stage flash distillation and reverse osmosis that are energy intensive. It then explains that solar desalination can help address future challenges of energy and water shortage. Solar desalination techniques include direct methods like solar stills and indirect methods that combine solar energy with conventional distillation. Both direct and indirect solar collection systems are discussed along with technologies like humidification-dehumidification that improve thermal efficiency. In conclusion, solar desalination offers a promising way to meet power and water needs in remote regions by providing alternatives to fossil fuel-driven processes.
purification of water using solar stillMohamed Ahmed
Distillation is one of many processes that can be used for water purification. This requires an energy input as heat, electricity and solar radiation can be the source of energy. When Solar energy is used for this purpose, it is known as Solar water Distillation. Solar Distillation is an attractive process to produce portable water using free of cost solar energy. This energy is used directly for evaporating water inside a device usually termed a “Solar Still”. Solar stills are used in cases where rain, piped, or well water is impractical, such as in remote homes or during power outages. Different versions of a still are used to desalinate seawater, in desert survival kits and for home water Purification. For people concerned about the quality of their municipally-supplied drinking water and unhappy with other methods of additional purification available to them, solar distillation of tap water or brackish groundwater can be a pleasant, energy efficient option. Solar Distillation is an attractive alternative because of its simple technology, non-requirement of highly skilled labour for maintenance work and low energy consumption.
The use of solar thermal energy in seawater desalination applications has so far been restricted to small-scale systems in rural areas. The reason for this has mainly been explained by the relatively low productivity rate compared to the high capital cost. However, the coming shortage in fossil fuel supply and the growing need for fresh water in order to support increasing water and irrigation needs, have motivated further development of water desalination and purification by renewable energies.
Our product is a solar desalination plant that utilizes solar energy to produce fresh water in a sustainable way. It uses large arrays of mirrors to concentrate sunlight onto a water container, heating the water and evaporating it. The water vapor then condenses in an insulated chamber to produce fresh water. This process requires no fossil fuels and instead uses an abundant renewable resource, solar energy, to provide fresh water for arid coastal regions in a cost-effective and environmentally friendly manner.
Solar distillation is a process that uses sunlight to purify water through evaporation and condensation. Approximately 97% of the world's water is salt water found in oceans, and solar distillation provides a simple way to purify this water for drinking. There are two main types of solar distillation systems - active systems that use extra thermal energy to increase evaporation rates, and passive systems that rely directly on sunlight. The document then discusses the history, basic concepts, components like basins and covers, energy transfer mechanisms, efficiency equations, design objectives, examples of large installations, advantages, and disadvantages of solar distillation systems.
The document presents an experimental study on improving the productivity of a single slope solar still by constructing a stepped basin. An experimental setup of a passive solar still with a stepped basin and glass cover was fabricated. Performance was tested with and without adding wicks to the basin. Results showed that productivity increased to over 6 liters per day for a 1 square meter basin area when multiple wicks were added. Overall productivity increased 20.5% when using wicks compared to without wicks due to increased evaporation and thermal storage effects of the wicks. Energy efficiency increased from 60% to 64.7% with the addition of wicks to the stepped basin solar still.
Box solar distillation is a simple method to distill water using sunlight. It consists of a glass-topped box held at an angle to allow sunlight to enter. Dirty or salt water is placed inside the box, where it evaporates from the sunlight and condenses on the inside of the glass top. The distilled water then drips into a collection tray for drinking water. It has advantages like being renewable, clean, and free of cost since it only uses sunlight for energy. The key components are a box, dirty water tub, glass cover, distilled water tray, and drain tube.
Solar distillation is the most reliable and least costly method of purifying contaminated water, especially in developing areas where fuel is scarce. The process uses solar energy to evaporate water which leaves impurities behind, then condenses the vapor into pure distillate. Various designs like single or multiple basin stills can be used, with efficiencies typically around 25-35%. While low cost, solar distillation has a disadvantage of low productivity that can be addressed through improvements to increase efficiency.
The document discusses solar water purification projects in disaster-affected coastal areas of Bangladesh. It describes how coastal communities suffer from lack of access to drinking water, having to travel long distances. The solar water pump (SWP) projects address this by pumping ground or surface water through pipelines to distribution points near households using solar energy. Over 122 projects have provided safe drinking water to over 50,000 households, totaling 1.9 million liters daily. Local management committees own and maintain the systems, collecting small fees for sustainability. The projects empower women by reducing time spent collecting water and enabling income generation opportunities as dispenser operators.

Effectiveness of Internal Audits in Public Educational Institutions in Kenya...IJMER
Internal auditing has become a factor of the new accountability and control era. The
manner in which public sector entities maintain internal control and how they are held accountable has
evolved to require more transparency and more accountability from these organizations that spend
investor or taxpayer funds. This trend has significantly impacted how management implements,
monitors, and reports on internal control. Although internal auditors can be a valuable advisory
resource on internal control, the internal auditor should not be a substitute for a strong internal control
system. A system of internal control is the primary response to risks. The role of internal auditing has
evolved from an administrative procedure with a focus on compliance, to an important element of good
governance. In many cases the existence of internal auditing is mandatory (intosaigov 9140).
This document discusses an autonomous network reconfiguration system (ARS) for multi-radio wireless mesh networks. ARS allows a network to self-recover from local link failures in order to maintain performance. It uses a reconfiguration planning algorithm to determine the minimum necessary changes needed for recovery. When a link failure is detected, ARS triggers the formation of a local group and designates a leader to coordinate reconfiguration. The leader requests a reconfiguration plan from a gateway, which is then implemented by group members to resolve the failure. ARS aims to reconfigure autonomously and locally in response to failures while limiting effects on healthy parts of the network.

Performance Evaluation of Push-To-Talk Group CommunicationIJMER
Recently the VoIP technology has been used for the purpose of voice conversation through the
Internet since the proliferation of smart phones. In this paper, we are interested in the network performance
of the group communication a.k.a. the push-to-talk (PTT) service. As the media traffic to a VoIP server
increases, the VoIP server can be a bottleneck and the voice quality can be declined, which results from the
asymmetry between the in-bound traffic and the out-bound traffic in a VoIP server. To simulate the voice
packet transfer of the group communication, we use ns-2.34 and the ns2VoIP++ package to calculate the
end-to-end mean opinion score. Simulation results show that both the packet error rate and the packet delay
have a significant effect on the performance in terms of the mean opinion score.
This document summarizes an investigation into the behavior of fly ash-based geopolymer concrete exposed to acidic environments. Fly ash-based geopolymer concrete and conventional concrete cubes were immersed in 5% hydrochloric acid, sulfuric acid, and magnesium sulfate solutions for up to 4 weeks. The geopolymer concrete exhibited much lower mass loss and higher residual compressive strength when compared to conventional concrete after acid immersion. For example, after 7 days of immersion the geopolymer concrete retained 89-96% of its original compressive strength, while conventional concrete retained only 75-90%. This confirms that geopolymer concrete has superior acid resistance compared to conventional concrete.

This document summarizes a study investigating the role of bulkheads and crack stopper straps in the fail-safe design of aircraft fuselages. A finite element analysis was conducted to model a section of fuselage containing longitudinal stiffeners, a bulkhead, and crack stopper straps. Stress intensity factors were calculated with and without the crack stopper straps to determine their effectiveness in arresting cracks. The analysis found that the crack stopper straps reduced stress intensity at the crack tip, improving the structure's ability to arrest cracks before they propagate catastrophically. This demonstrates the importance of bulkheads and crack stopper straps in achieving the damage tolerance designed to safely sustain cracks in aircraft fuselages.

An experimental investigation into the performance of a gi basin passive sola...eSAT Journals
Abstract Potable Water or Pure Drinking Water is essential to mankind and it is difficult to obtain fresh water at many places . The conventional methods available to purify Water are costly. Solar Energy is freely available and can be used as a very cheap option to purify Water through Solar Distillation, by using Solar Stills . The conventional Single Basin Passive Solar Still or Plain Basin Galvanized Iron (GI) Solar Still can be used to purify Water but the main problem is that the per square metre distillate output is less. Many methods have been used to increase the output of GI Basin Solar Still. Horizontal or Vertical Mesh made of GI can be used in the Basin of Solar Still to increase the distillate output. Outdoor Experiments were conducted at Nagpur, Maharashtra ,India (21.15⁰N, 79.09⁰E) for GI Basin Plain (Without Mesh) Solar Still, With Horizontal Mesh and With Vertical Mesh in the months of May-June and September-October. It was found that both the Mesh increase the distillate output considerably, in which the Horizontal Mesh gives an appreciable increase in the Average Distillate Output (about 400ml per day) and an increase of about 6% in the Average Distillation Efficiency whereas the Vertical Mesh gives a significant increase in the Average Distillate Output (about 1000ml per day) with an increase of about 13% in the Average Distillation Efficiency. The Vertical Mesh is very cheap and the payback period for the Vertical Mesh is hardly 3 months. Thus , the GI Basin Solar Still with Vertical Mesh gives a higher output and can be helpful in obtaining pure drinking water for communities , both cheaply and effectively. Key Words : GI Basin Solar Still, Distillate Output, Average Efficiency, Horizontal Mesh, Vertical Mesh

The Greenstone belts of Karnataka are enriched in BIFs in Dharwar craton, where Iron
formations are confined to the basin shelf, clearly separated from the deeper-water iron formation that
accumulated at the basin margin and flanking the marine basin. Geochemical data procured in terms of
major, trace and REE are plotted in various diagrams to interpret the genesis of BIFs. Al2O3, Fe2O3 (T),
TiO2, CaO, and SiO2 abundances and ratios show a wide variation. Ni, Co, Zr, Sc, V, Rb, Sr, U, Th,
ΣREE, La, Ce and Eu anomalies and their binary relationships indicate that wherever the terrigenous
component has increased, the concentration of elements of felsic such as Zr and Hf has gone up. Elevated
concentrations of Ni, Co and Sc are contributed by chlorite and other components characteristic of basic
volcanic debris. The data suggest that these formations were generated by chemical and clastic
sedimentary processes on a shallow shelf. During transgression, chemical precipitation took place at the
sediment-water interface, whereas at the time of regression. Iron ore formed with sedimentary structures
and textures in Kammatturu area, in a setting where the water column was oxygenated.

Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

Material Parameter and Effect of Thermal Load on Functionally Graded CylindersIJMER
The present study investigates the creep in a thick-walled composite cylinders made
up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution
of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of
the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep
law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is

required in the study. The basic equilibrium equation of the cylinder and other constitutive equations
have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle
content and temperature on the stresses in the composite cylinder has been analyzed. The study
revealed that the stress distributions in the cylinder do not vary significantly for various combinations
of particle size, particle content and operating temperature except for slight variation observed for
varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development
of superior heat resistant materials.

Abstract: Various aspects of single basin solar still with evacuated tubes solar collector have been discussed in this paper
with a focus on the use of evacuated tubes to increase the daily productivity of solar still with less heat losses. The pure
water can be obtained by distillation in the simplest solar still. Various active methods have been adopted to increase the
temperature of the basin so as to improve the productivity of solar still.
Keywords: Augmentation, distillation, evacuated tubes, Solar still.
I. Introduction
Water is a precious natural gift and is being polluted by human activities, urbanization and industrialization. The
ground water is often over exploited to meet the increasing demand of the people. Less than 1% of earth‟s water is available
for human consumption and more than 1.2 billion people still have no access to safe drinking water. Over 50% of the world
population is estimated to be residing in urban areas, and almost 50% of mega cities having population over 10 million are
heavily dependent on ground water, especially in the developing countries like India .
Most of the rural people still live in absolute poverty and often lack access to clean drinking water. Nearly half of
the population is illiterate, not at all aware of the waterborne diseases affecting their health. Nearly 70% of the infectious
diseases in India are waterborne. Indian villages are posed with problem of overexploitation of ground water due to
increasing dependence on it as other fresh water resources are dwindling fast. Various desalination techniques are used to
purify the water. Solar distillation is an easy and cost effective method to provide pure drinking water in rural areas without
affecting the nature. Solar distillation process is carried out both in passive and active modes. [13]
Passive Method: Passive solar still operates in low temperature and the daily productivity is comparatively low.
Active method: To increase the evaporation rate in an active mode the extra thermal energy is fed into the basin. To increase
the productivity of solar still, the various active methods are being carried out by many researchers. Most of the works were
based on the flat plate collector and concentrating collector.
Following are the various active methods to increase the productivity of solar still.
Basin type solar still: Such solar stills have been operated for farm and community use in several countries. It consists of a
blackened basin containing saline water at a shallow depth, over which is a transparent air tight cover that encloses
completely the space above the basin. It has a roof-like shape. The cover which is usually glass, may be of plastic is sloped
towards a collection trough. Solar radiation passes through the cover and is absorbed and converted into heat in the black
surface. Impure water in the basin or tray is heated and the vapor produced is condensed to purified water on the cooler
interior of the roof. The transparent roof material, (mainly glass) transmits nearly all radiation falling on it and absorbs very
little; hence it remains cool enough to condense the water vapor. The condensed water flows down the sloping roof and is
collected in troughs at the bottom. [1], [2], [3]
Vertical solar stills with a flat plate solar collector: The distillation unit consists of „n‟ parallel vertical plates. The first
plate is insulated on its front side and the last plate is exposed to ambient. Each plate in the enclosure is covered with wetted
cloth on one side. The cloth is extended into a feed through along the upper edge of each plate. Feed water in the through is
then drawn onto the plate surface by capillary. Excess water moves down the plate and is conducted out of the still. The last
plate is cooled by air or water. The authors found that, the distillation output increases slightly when the plate number is over
5, and it increased by about 34% and 15% when the evaporating plate numbers are 1 and 6, respectively. [4], [5].
Solar still integrated with mini solar pond: Solar pond is an artificially constructed pond in which significant temperature
rises are caused to occur in the lower regions by preventing convection. Solar ponds are used for collection and storage of
solar energy and it is used for various thermal applications like green house heating, process heat in dairy plants, power
production and desalination.
The results show that, average increase in productivity, when a pond is integrated with a still is 27.6% and when
pond and sponge are integrated with a still is 57.8%. Industrial effluent was used as feed for fin type single basin solar still
and stepped solar still. A mini solar pond connected to the stills to enhance the productivity and tested individually. The
results show that, maximum productivity of 100% was obtained when the fin type solar still was integrated with pebble and
sponge. The productivity increases with increase in solar intensity and water glass temperature difference and decreases with

increase in wind velocity. Pebbles, baffle plates, fins and sponges are used in the stepped solar still for productivity
augmentation. Their finding shows that, maximum productivity of 78% occurred when fins and sponges were used in the
stepped solar still and also found that the productivity during night also improved when pebbles were used in the solar stills.
[10], [11], [12].
There are three main types of solar stills: the box solar still, the cone solar still and the pit solar still
II. Box Solar Stills
The box shaped solar still is fairly complex compared to the other solar stills made for obtaining pure emergency
drinking water. This type of still is usually created with a box that has a slanted glass or plastic top with an insulated bottom.
A set of tubes allow in impure water and let out over flow and pure distilled water. Maintaining a tight seal on a box shaped
solar still is essential. Clearly, this is more of a home project for a green minded person, but having a solid understanding of
how all solar stills work might come in handy when trying to construct one from scratch for emergency drinking water.
Figure 1: Box type solar still
III. Cone Solar Still
A cone shaped solar still is a method of treating impure emergency drinking water rather than gathering it from the
atmosphere. A cone is constructed out of plastic designed so that impure water in the bottom evaporates and is captured in a
makeshift reservoir as it runs down the side, relieved of impurities. The Water cone is commercial solar still that allows you
to distill water naturally at home or on the go with having to construct a solar still of your own. Designed as a water
purification system that can generate potable water out of even brackish sea water, the Water cone is also a candidate for
providing clean drinking water in developing and failed nations.
Figure 2: Cone type solar still
IV. Pit Solar Still
Pit shaped solar stills are the simplest solar still to make and require little equipment or technical know-how. Simply
dig a pit in the earth approximately two feet deep and place a Number 10 sized can at the bottom. If available, set a drinking
tube in the bottom of the can leading out of the hole. Then secure a sheet of plastic over the hole a place a stone in the sheet
so that it indents the sheet to just above the can's lid. So long as this solar still receives plenty of sun, it will provide a pint or
more of emergency drinking water. [15]

V. Literature Survey
Solar Still alone:
An experimental study is conducted by Bhanu Pratab Singh [1] in a single slope solar still integrated with solar water
heater. It has been found that still productivity increases up to 120% when combined with solar water heater. Also, the
ambient conditions are found to have direct effect on the productivity of the still. The production in night in the absence
of solar radiation contributes up to 14% of the daily output due to availability of hot water as basin water with the
integration of solar water heater.
The work carried out by Ahmed Z. AL-Garni. [2] To enhance the productivity of a double slope solar still by using an
immersion type water heater. The effect of using an external fan to cool the glass surface is also examined. Experiments
were carried out for winter season in Saudi Arabian climatic conditions at solar still is more for low water depths, the
water level in the base tank was maintained at 1cm. The experimental results showed that the productivity increased by a
significant 370% when two water heaters each having 500 W capacities was used. When external cooling fan was used
the productivity was found to decrease by 4% and 8% for wind speeds of 7 m/s and 9 m/s, respectively.
V. Velmurugan, et al. [3] performed productivity enhancement of stepped solar still. For comparison purpose, the
ordinary stepped solar still is tested without any modification and the average water productivity is found to be 1.01
litres per 8 hour. To improve the productivity, theoretical and experimental analyses were made for fin type, sponge
type, and combination of fin and sponge type stepped solar still. When the fin and sponge type stepped solar is used, the
productivity is 1.98 litres per 8 hours which is 96% more compared to the productivity of ordinary stepped solar still.
The average daily water production has been found to be 80% higher than ordinary single basin solar still.
Solar still coupled with flat plate collector:
Badran and Al-Tahainesh [4] presented the effect of coupling a flat plate collector on the solar still productivity. It has
been found that coupling of a solar collector with a still has increased by 36%. The results showed that, the output of the
still is maximum for the least water depth in the basin (2 cm). Also, the increase in water depth has decreased the
productivity, while the still productivity is found to be proportional to the solar radiation intensity.
A work is carried out by A.M. Rajesh, et al. [5] on single basin solar still integrated with a flat plate collector [FPC]. A
single stage basin type solar still and a conventional flat plate collector were connected together in order to study the
effect of augmentation on the still under local conditions. The still inlet was connected to a locally made fin tube
collector. The unit as operated with and without coupling flat plate collector. Measurements of various parameters,
temperatures, solar intensities and distilled water production were noted between 8 AM to 5 PM sunlight day.25 to 40%
enhancement in the yield is observed with this system.
Solar still coupled with parabolic concentrator:
Zeinab and Ashraf [6] conducted experimental and theoretical study of a solar desalination system coupled with solar
parabolic through with a focal pipe and simple heat exchanger. The results show that, as time goes on, all the
temperatures increase and begin to decrease after 4.00 pm with respect to the solar radiation, although the temperature
values of the modified system are still higher than the conventional one. In case of the modified design, the fresh water
productivity increased an average by 18%.
Garcia Rodriguez and Gomez Camacho [7] experimentally studied the multi effect distillation system coupled to a
parabolic through collector (PTC) for sea water desalination and suggested the following, (i) the annual energy
production is about 23% grater for a north–south collector than for an east west one. (ii) The optimum axis height for a
single collector is 298 and it is 12% higher production than a horizontal collector for an inlet/outlet thermal oil
temperature of 225 o
C /300 o
C. (iii) The maximum yearly average of the daily operation time is only about 12 h/day in
coastal areas in southern Spain.
T. Arunkumar , R.Jayaprakash[8] performed Desalination Process Of Single Slope Solar Still Coupled In CPC With
Crescent Absorber using two modes of operation: (1) Single slope solar still top surface open condition operating with
crescent absorber, (2) Single slope solar still top surface closed condition which is operating with crescent absorber for a
period of 9:00 hours to 16:00 hours. In the first modes of the operation the productivity the still 2.1 litres per day and
1.03 litres/ day for second mode of the operation. The efficiency of the first mode of study is calculated as 23.19% and
13.01% is the second mode of the still performance.
T. Arunkumar et. al. [9] conducted experimental study on a compound parabolic concentrator tubular solar still tied with
pyramid solar still. These type of behaviour is studied by using of a pyramid solar still directly coupled with compound
parabolic concentrator – tubular solar still in this work. These results showed that the maximum output extracted from
the proposed system as 6928 ml/m2
/day for with cooling. The overall efficiency of the system is calculated as 17.01%
for without cooling and 21.14% for with cooling.
Solar Still Integrated to Solar Pond:
Performance analysis of vapour adsorption solar still integrated with mini-solar pond for effluent treatment is done by
Dr. K. Srithar [10]. To enhance the productivity, the single basin solar still was modified with activated carbon,
methanol with sponge, pebbles and sand were used. The overall productivity of the still is increased by 32.32 %.

The experimentation was carried out by V. Velmurugan; et al. [11] on solar stills integrated with a mini solar pond and
found that the productivity is maximum. Optimum salinity of 80gm/kg of water was used in solar pond. Productivity of
still alone was found to be 2.77 L/m2
/day. And when sponge cubes is used in solar still production rate is increases by
about 33%, i.e. 3.3 L/m2
/day. When a mini solar pond was integrated with solar still productivity is increased by about
58%. I.e. 3.4 L/m2
/day. But maximum productivity is obtained when the sponged solar still is integrated with the mini
solar pond, i.e. 4.4 L/m2
/day.
Velmurugan et al. [12] experimentally investigated the possibility of enhancing the productivity of the solar stills by
connecting a mini solar pond, stepped solar still and a single basin solar still in series. Pebbles, baffle plates, fins and
sponges are used in the stepped solar still for productivity augmentation. Their finding shows that, maximum
productivity of 78% occurred when fins and sponges were used in the stepped solar still and also found that the
productivity during night also improved when pebbles were used in the solar stills.
Solar still coupled with evacuated tube:
The solar still coupled with evacuated tubes were carried out by K. Sampathkumar, et al. [13] to enhance the
productivity of the solar still. These experiments were conducted using tap water as feed. It was found that, after
augmentation of the evacuated tubes, the daily production rate has increased by 49.7 % and it increased by 59.48% with
black stones.
Ahmed et al. [14] designed, fabricated and tested the multistage evacuated solar still system that consists of three stages
stacked on the top of each other. The results show that, the maximum production of the solar still was found in the first
stage and is 6 kg/m2
/day, 4.3 kg/ m2
/day in second stage and 2 kg/m2
/day in first stage at a vacuum pressure of 0.5 bars.
Indeed, the total productivity of the solar still is affected very much by changing the internal pressure. The productivity
decreased as the pressure increased due to the lower evaporation rates at the higher pressure values.
VI. Conclusion
The forgone discussion on the use of solar still system suggests that there is a need for developing a reliable and
higher productivity solar still. The review is focused on the still coupled with solar collectors, Solar still coupled with flat
plate collector, solar still coupled with parabolic concentrator, Solar still integrated to Solar Pond and solar still coupled with
evacuated tube are discussed and their effectiveness are compared. The review is mainly focused on production of distilled
water from Single Basin Solar Still with Evacuated Tubes Solar Collector.
