Removal of heavy metal lead (pb) from electrochemical industry waste water us...eSAT Journals
Abstract Electrochemical industries generates a wastewater that has a potential hazard for our environment as it contains various heavy metals such as Lead, Cadmium, Nickel etc. If this wastewater left untreated, will pollute soil and water resources. Out of the above heavy metals, in this project work, only removal of Lead (Pb) from electrochemical industrial wastewater has been investigated by using low cost adsorbent such as charcoal along with coconut shell powder as a natural adsorbent. The project is a bench scale experimental type i.e. Batch mode technique and analyses have performed by using different amounts of adsorbent in solutions with different concentrations of Lead metal. Beside the effect of various amounts of adsorbent used in adsorption efficiency experiments has been investigated. Result indicates that the maximum removal efficiency for Lead is about 94% by using 0.25 gm/L amount of activated coconut shell carbon powder (ACSCP) and charcoal powder (ACP) mixed in equal amount for particular pH and contact time. Keywords: Adsorption, batch mode technique, battery industry waste water, Coconut shell powder, Charcoal carbon powder, Economic, Heavy Metal.
A Review on Applicability of Photocatalyst Titanium dioxide for Treatment of ...IJERA Editor
Greywater reuse has attracted great attention for sustainable management of water especially under water
scarcity conditions. However, the effort has been limited by the presence of toxic organics in the effluent which
in turn inhibits the public acceptance of recycling water. The existence of those organic pollutants, which cannot
be eliminated by conventional primary and secondary treatment processes, can be problematic. Hence it is
necessary to explore a sustainable, robust and affordable method for treatment of greywater. Photocatalytic
oxidation is an emerging technology that could be suitable to remove refractory organic compounds found in
greywater. Recently titanium dioxide (TiO2) gained wide attention for photocatalytic oxidation of organic matter
of wastewater. Because it is biologically and chemical inert, resistant to chemical corrosion and can work at
ambient temperature and pressure, without addition of chemical species. The irradiation of titanium dioxide
dispersions by ultraviolet (UV) (300-400 nm) light can lead to the formulation of highly reactive hydroxyl
radicals which attack the pollutant molecule to degrade it into carbon dioxide, water and mineral acids.This
technology has advantages, such as, the integration into small places, low maintenance and easy operation.

Chemo bio synthesis of silver nanoparticlesJagpreet Singh
Silver nanoparticles have a lot of ways of synthesis like physical and chemical
methods; some of these methods use a lot of chemical substances and are
very hazardous for humans and environment, so a novel, great, environmental
friendly, cheap and easy to use world of green chemistry has been used. A
number of characterization techniques such as UV-visible spectroscopy, Fourier
transformation infrared spectroscopy, X-ray diffraction study and scanning
electron microscopy revealed that silver nanoparticles have been used. Thus
the different response of the functional groups and the difference in the peaks
and UV-visible data was studied and then compared to understand and know
the way these different reducing agents react to the same starting material. The
green synthesis had a UV-visible peak at 446 nm while the one with chemical
synthesis had a peak at 395 nm. FTIR results of silver nanoparticles synthesis
by trisodium citrate (TSC) showed a peak at 1505 cm-1 which shows that the
compound has a stretching of the -C=C – bond. In another case, which was done
by using Sodium borohydride (NaBH4) a peak at 1695 cm-1 showed a –C=O- bond
indicating stretching and a weak absorption intensity. Another peak was present
which indicates a –O-H bond formation and presence which is a strong bond are
found to exist. A notable peak came for synthesis by orange peel at 1517 cm-1
which represents a –C=C- bond stretching as in aromatic compounds. Another
peak at 1732 cm-1 indicates the –C=O- bond. The XRD results on one of the
silver sample prepared by green methods showed silver nanomaterials formed
which had a average particle size of around 42 nm. FE-SEM results revealed that
silver nanomaterials were formed and had a flake like appearance in one of the
results. All the overall comparison showed that different modes of synthesis
of silver nanomaterials and different reducing agents give same materials but
with different peaks and intensities. All this data provided knowledge about the
fact that an alternative method can be used to create new nanoparticles if one
of the previously considered to tried method fails thus helping in extending the
broadways for research.

A study on leachate characteristics generated from waste foundry sand and its...eSAT Journals
Abstract Metal foundry industries use sand as the major part in the metal casting process. Foundry industries are the industries which mould the metal (alloy) castings, the castings are casted by using the molten metals, which are poured into the moulds prepared by the sand (usually known as foundry sand), and here the foundry sand is subjected to the temperature which is higher than 1000ºC in the moulding process. The waste sand obtained after the casting, cannot be used further and thus the Waste Foundry Sand (WFS) is removed from the foundry industry and it is known as waste foundry sand. Waste foundry sand generated from the metal foundries is indiscriminately dumped in the low lying areas of Belagavi city. Belagavi city receives high annual rainfall around 1200 mm. The WFS dumped contains the heavy metal concentrations. Leachate is generated from the WFS containing heavy metals and the heavy metals are leached from the WFS, thus the ground water is contaminated. Water samples from a lake, 5 open wells and a bore well in the Udyambag area were collected and analyzed for Physico-chemical characteristics and heavy metal concentrations. The leaching effect of the WFS is analyzed using TCLP. The leaching effect of the WFS is also studied when it is a part of pervious concrete and the heavy metal analysis is carried out. The ground water and surface water body study includes the Physico-chemical parameters like chlorides, TDS, SC, pH, turbidity, colour, odour, temperature and the heavy metals like barium, total chromium, iron, lead and manganese.

COD reduction of aromatic polluted waste water by Advanced Oxidation Process ...Wade Bitaraf
In most petrochemical complexes and oil refineries the wastewater contains the aromatic compounds among which Benzene, Toluene, Ethyl Benzene and Xylene (BTEX) have harmful effects on environment and human health. The present work mainly deals with the UV-based advanced oxidation processes (AOPs), UV/H2O2 were tested in batch reactor systems to evaluate the removal efficiencies and optimal conditions for the photodegradation of BTEX in order to wastewater treatment. The efficiency of this method was analyzed by evaluating the Chemical Oxygen Demand (COD) as a pollution criterion through the COD reactor. The influence of the basic operational parameters such as initial concentration of H2O2, pH, Temperature, irradiation time and UV amount on the photo degradation of BTEX were also studied. The oxidation rate of BTEX and respectively the reduction rate of COD were low when the oxidation was carried out in the absence of H2O2 or UV light. The addition of proper amount of hydrogen peroxide improved the degradation, while the excess hydrogen peroxide could quench the formation of hydroxyl radicals (•OH). The optimal conditions of suspended slurry with 1.11(g/l) initial concentration of H2O2 and pH value of 3.1 were obtained under three UV lights illumination (6 W). Under the optimal conditions, COD reduction during the initial period of 180 min in UV/H2O2 systems reached about 90%.

Biosorption of Copper (II) Ions by Eclipta Alba Leaf Powder from Aqueous Solu...ijtsrd
The removal of heavy metals from industrial wastewater is of great concern as heavy metals are non-biodegradable, toxic elements that cause serious health problems if disposed of in the surrounding environment. The present study, Karisalangkani (Eclipta Alba) leaves were used for the adsorption of heavy metals like copper (Cu (II)) ions. The bio sorbent was characterized using SEM and BET analysis. The bio sorption experiments are conducted through batch system. The operating parameters studied were initial metal ion concentration, adsorbent dosage, initial solution pH, contact time and effect of temperature Adsorption equilibrium is achieved in 30 min and the adsorption kinetics of Cu (II) is found to follow a pseudo-second-order kinetic model. Equilibrium data for Cu (II) adsorption are fitted well by Langmuir isotherm model. The maximum adsorption capacity for Cu (II) ions is estimated to be 9.2 mgg at 25 °C. The experimental result shows that the materials have good potential to remove heavy metals from effluent and good potential as an alternate low cost adsorbent. Due to their outstanding adsorption capacities, Eclipta Alba is excellent sorbents for the removal of copper (II) ions. B. Kavitha | R.

Removal of Pb II from Aqueous Solutions using Activated Carbon Prepared from ...ijtsrd
The recent study explains about the removal of Pb II ions from aqueous solution using activated carbon prepared from Garlic waste. Garlic peels have been used for the production of Carbon by treating with conc.H2SO4 for metal ions removal. Fourier Transform Infrared Spectroscopy and Boehm titration have been used for various physicochemical characterization of the outcome of activated carbon which proclaimed the presence of oxygen containing surface functional groups like phenolic, lactonic and carboxylic in the carbons. In a batch adsorption process the effect of pH and initial metal ion concentration was calculated. The optimum pH for lead adsorption is found to be equal to 6.The resultant activated carbon showed maximum adsorption capacity of Pb II was 210 mg g 1. The waste material which is used in this work is cost effective and easily available for the production of activated carbon. Hence the removal of Pb II from water using the carbons prepared from Garlic peels can act as possible low cost adsorbents for the removal of Pb II from water. R.

Physico chemical Analysis of Groundwater near Dumping Site of Gorakhpur Cityijtsrd
Groundwater is the water present beneath Earths surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. 1 A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, permafrost frozen soil , immobile water in very low permeability bedrock, and deep geothermal or oil formation water. Groundwater is hypothesized to provide lubrication that can possibly influence the movement of faults. It is likely that much of Earths subsurface contains some water, which may be mixed with other fluids in some instances. Groundwater is often cheaper, more convenient and less vulnerable to pollution than surface water. Therefore, it is commonly used for public water supplies. For example, groundwater provides the largest source of usable water storage in the United States, and California annually withdraws the largest amount of groundwater of all the states. Underground reservoirs contain far more water than the capacity of all surface reservoirs and lakes ,, including the Lakes. Many municipal water supplies are derived solely from groundwater. Over 2 billion people rely on it as their primary water source worldwide. Use of groundwater has related environmental issues. For example, polluted groundwater is less visible and more difficult to clean up than pollution in rivers and lakes. Groundwater pollution most often results from improper disposal of wastes on land. Major sources include industrial and household chemicals and garbage landfills, excessive fertilizers and pesticides used in agriculture, industrial waste lagoons, tailings and process wastewater from mines, industrial fracking, oil field brine pits, leaking underground oil storage tanks and pipelines, sewage sludge and septic systems. Additionally, groundwater is susceptible to saltwater intrusion in coastal areas and can cause land subsidence when extracted unsustainably, leading to sinking cities and loss in elevation. These issues are made more complicated by sea level rise and other changes caused by climate changes which will affect the water cycle.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
