The present study deals with the assessment of toxicity of distillery effluent on soil microorganisms and its quality improvement through bioremediation using Pseudomonas spp. Under lab scale experiment, different dilutions of distillery effluent i.e. 25%, 50%, 75% were used to examine effects on physico-chemical parameters of effluent and on soil microflora e.g. algae, bacteria, fungi and acti...

Isocyanates are a group of low molecular weight, highly reactive compounds with a functional isocyanate group. The main human exposure route is via inhalation of airborne isocyanates, although dermal exposure has also been reported. The inhalation of isocyanates is associated with severely adverse health effects such as asthma, inflammation in the respiratory tract and cancer. During thermal de...

To utilize the energy in thermal effluent, many attempts have been made to use effluent for agricultural facilities such as greenhouses. As first step, it is important estimate loads of greenhouse deciding a suitable scale heating and cooling. Then, available efficiency heat pump system installed greenhouse. Therefore, main objectives this study were design validate an model experimental growin...

2-Chlorobenzylidenemalononitrile (CS riot control agent) has been shown to produce a number of thermal degradation products when dispersed at high temperature. We hypothesized that these CS-derived compounds are formed by energy input from heating during the dispersion process. Here we identified organic CS-derived compounds formed from purified CS subjected to temperatures ranging from 300 to ...

A study was performed to evaluate capability of aquatic macrophyte Eichhornia crassipes plants to combat oxidative stress caused by tannery effluent treatment. For this purpose, tannery effluent was collected from “Up flow Anaerobic Sludge Blanket” (UASB) Jajmau, Kanpur. Plants of Eichhornia crassipes were exposed to various concentrations of tannery effluent (0.0, 25, 50, 75 and 100%) for 2 an...

The toxicity of Cu to Daphnia magna was investigated in a series of 48-h immobilization assays in effluents from four wastewater treatment works. The assay results were compared with median effective concentration (EC50) forecasts produced by the HydroQual biotic ligand model (BLM), the refined D. magna BLM, and a modified BLM that was constructed by integrating the refined D. magna biotic liga...

The objective of this study was to explore the extent of mineralization of Biodigester Effluent (BDE) by Electrochemical Treatment using aluminum electrodes in monopolar configuration. The benefit of determining a COD/TOC ratio is becoming evident. While both parameters are useful independently, the ratio of the two values, and the fluctuation of this ratio, is an excellent indicator of the org...
