This document provides details on the design of components for a carp hatchery complex. It discusses calculating brood fish requirements based on production targets, sizing spawning and incubation pools, and estimating nursery pond area. Brood fish of 1300kg are needed for 50 million spawn production annually. A 5m diameter spawning pool and 2.4m diameter incubation pool are designed to support 30 lakh egg production. A 15,000 liter overhead water tank is sized to supply these units. A 2.5 hectare nursery area is required to rear 50 million fry over 5 crop cycles.
The type of handpump technology suitable for a particular area depends on the groundwater level, water quality and hydrogeological conditions. There are some areas like the costal belt in the southern part of Bangladesh, where the conventional shallow and deep tubewlls technologies are not successful due to the high salinity. Alternative water supply options are needed for those areas.

An Aqua Silencer replaces a conventional silencer and consists of a perforated tube installed at the end of the exhaust pipe inside a water container. Exhaust gases pass through the perforated tube which breaks the gases into smaller bubbles, and then through an activated charcoal layer and water. Some gases dissolve in the water, while others pass through and are released. Tests have shown Aqua Silencers can reduce carbon monoxide emissions by 60-70% compared to conventional silencers. They are more effective at reducing noise and controlling air pollution than conventional silencers.
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.
Survey of aeration management in shrimp farmingAlberto Nunes
This document discusses aerated pond management for shrimp farming. It provides information on:
- The importance of adequate dissolved oxygen for shrimp health and survival, and the factors that influence oxygen levels in ponds.
- Common types of mechanical aerators used in aquaculture ponds, including paddlewheel aerators, propeller-aspirator pumps, and diffused-air systems.
- Key findings from a survey of 140 shrimp farms on their aeration practices, including typical pond sizes, aeration rates, species cultured, and aerator positioning strategies.
- How mechanical aeration is used to supplement natural oxygen levels, improve water quality, and increase pond production capacities.
Singapore obtains NEWater through an advanced purification process that involves microfiltration, reverse osmosis, and ultraviolet disinfection of used water. This recycled water is a more affordable and sustainable alternative to desalination or increased water imports. NEWater production removes bacteria, viruses, and other contaminants to provide a high-quality source of non-potable water to supplement Singapore's water supply.
IRJET- Experimental Work by Vacuum Methodology Study on Waste WaterIRJET Journal
The document describes an experimental study on wastewater treatment using vacuum filtration methodology. The study collected wastewater from residential areas and treated it using reverse osmosis (RO) filtration to purify the water by removing contaminants. Testing showed that the RO filter was able to absorb 3-5 liters of water per hour. The treated water was then suitable for reuse applications like gardening. Vacuum filtration was used to rapidly draw the wastewater through a filter. Activated carbon filtration was also utilized to remove gases, smoke particles, bacteria, chemicals and other pollutants from the water. The treated water met purity standards for reuse after processing the wastewater through the RO filtration system.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

5. AQUASPURT
replacing water paddle wheels
Making lots of dissolved oxygen
The old fashion water paddle wheel only stirred the water to make
bubbles by the blades. By this way it can not cut the water into
small particles. This is why the dissolved oxygen is not enough for
aquacultures in the pond especially before dawn.
Unlike the traditional water paddle wheel, AQUASPURT cut the
water into small particles for 800 liters per minute. Later on the
small water particle will be sprayed into the air for 2-3 second so as
to absorb more oxygen and be back the pond. This is why by using
AQUASPURT will get more oxygen and make the eco
environmental healthier and have more harvest especially before
dawn.

Aerating circulation of the bottom pond
By using the traditional water paddle wheel, the headache problems of excluding
NO2,NO3,H2S,NH4 and other harmful materials could not be solved. Unlike the old
equipment, AQUASPURT can solve it easily by spraying small water particle of the
bottom pond into the air. When the small water particle floating the air, the harmful
materials would be eliminated and sterilized by the sunlight to make better eco
environment to aquacultures.
