In the present study, performance of mixed microbial anaerobic culture in treating synthetic strong wastewater containing different concentration of atrazine was evaluated (R-1). Studies were also conducted in two hybrid reactors (A-1 and A-2) with wood charcoal as adsorbing matrix along with microbes. All the reactors for the treatment of atrazine bearing wastewater were operated in sequential...

The accepted method for determining disinfection efficiency of wastewater treatment systems is routinely to perform fecal coliform bacteria analyses on the final effluent (5). Standard Methods for the Examination of Water and Wastewater outlines two procedures for fecal coliform analysis: the membrane filtration technique and the most-probable-number (MPN) method (1). For chlorinated effluents,...

Global aquaculture production has expanded at an average annual rate of 6.2% during 2000-2012, with world aquaculture production of 66.7 million tons in 2012, outpacing world population growth rate of 1.6%. According to Food and Agriculture Organization (FAO), aquaculture is estimated to supply 62% of the world’s fish for human consumption by 2030. However, aquaculture produces huge volumes of ...

BACKGROUND This study investigated the oxidation of selected progestagenic steroid hormones by potassium permanganate at pH 6.0 and 8.0 in ultrapure water and wastewater effluents, using bench-scale assays. Second order rate constants for the reaction of potassium permanganate with progestagens (levonorgestrel, medroxyprogesterone, norethindrone and progesterone) was determined as a function of...
