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...

This study was conducted at the ethanol plant of Metehara sugar factory, a laboratory scale, to assess effect recycling vinasse into fermentation process on effluent reduction. Vinasse is an produced from distilleries. The experimental design included concentrations 4 dilution rates (0 (control), 20, 35, 50, and 65% water) with 2 replicates 6 responses, as follows: yield, efficiency, residual c...

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 Beaudesert Sewage Treatment Plant (STP), originally built in 1966 and augmented in 1977, is a typical biological trickling filter (TF) STP comprising primary sedimentation tanks (PSTs), TFs and humus tanks. The plant, despite not originally being designed for nitrogen removal, has been consistently achieving over 60% total nitrogen reduction and low effluent ammonium concentration of less t...
