Leather industry, one of the polluting industries because of generation of huge amount of liquid and solid wastes, also emits obnoxious smell because of degradation of proteinous material of skin and generation of gases such as NH3, H2S and CO2. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing dusts and keratin wastes. Accumulation of these wastes lead to sludge problem and c...

River Hindon is one of the most polluted rivers in western Uttar Pradesh, India. Treatment of Hindon river water is a challenging task due to large variety of inorganic, organic chemicals and microorganisms. The objective of present work is to study the application of electrochemical technique in the treatment of polluted Hindon river water. Experiments were carried out in an electrochemical ce...

Controlled tile drainage (CTD) can reduce pollutant loading. The Annualized Agricultural Nonpoint Source model (AnnAGNPS version 5.2) was used to examine changes in growing season discharge, sediment, nitrogen, and phosphorus loads due to CTD for a ∼3900-km agriculturally dominated river basin in Ontario, Canada. Two tile drain depth scenarios were examined in detail to mimic tile drainage cont...

2. The dissolved-phase fraction (fdissolved) is a function of the characteristics and level of suspended solids and dissolved organic matter, which may be estimated from the following relationship, where [SS] is suspended solid content, [DOC] is DOC concentration, kd is partition coefficient between the dissolved phase and the suspended solids, and kDOC is the partition coefficient between the ...

the automobile industry’s wastewater not only contains high levels of suspended and total solids such as oil, grease, dyestuff, chromium, phosphate in washing products, and coloring, at various stages of chassis manufacturing but also, a significant amount of dissolved organics,resulting in high bod or cod loads. suspended solids can be removed from the wastewater by chemical precipitation. h...

Experiments were done to determine if bacteria able to utilize phenanthrene as a sole source of carbon obtain the hydrocarbon directly from solid phenanthrene particles suspended in the medium or from the phenanthrene dissolved in the medium. Growth experiments were done in gas-tight fermentors completely filled with air-saturated, mineral salts solution with phenanthrene as the substrate. Gene...
