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...

Hardwood KP bleaching effluents, before (influent) and after (effluent) biological treatment, were characterized and compared to identify the main bio-recalcitrant organic compounds in the effluent. The results indicate that biological treatment reduces CODcr and BOD5 by 67% and 88%, respectively. However, various bio-recalcitrant organic compounds were still retained in the biologically-treate...

ammonia (nh3) and nitrite (no2) toxic chemicals which resulted from fish culture, especially in intensive fish culture systems. to evaluate the efficiency of green algae scenedesmus quadricauda in ammonia and nitrite removal from intensive fish farm effluent and also its application as suitable culture medium for s. quadricauda , effluent water samples were collected from rainbow trout farm. si...

Adsorption of poliovirus from primary sewage effluent was similar to that from secondary sewage effluent in both batch soil studies and experiments with soil columns 240 cm long. Virus desorption by distilled water was also similar in a soil column that had been flooded with either primary or secondary effluent seeded with virus. These results indicated that absorption of poliovirus from primar...
