To develop a better understanding of the issues and best practices related to the use of treated effluent to help maintain river flows and habitat, the Conservancy commissioned a study to summarize the state of the science. The use of treated wastewater effluent is becoming a more prominent factor in Arizona’s overall water management strategy. Treated effluent contains a wide array of chemical...

Anaerobic fluidized membrane bioreactors (AFMBRs) have been mainly developed as a post-treatment process to produce high quality effluent with very low energy consumption. The performance of an AFMBR was examined using the effluent from a microbial fuel cell (MFC) treating domestic wastewater, as a function of AFMBR hydraulic retention times (HRTs) and organic matter loading rates. The MFC-AFMB...

background & aims of the study: detergent and phosphate are one of the main and vital threats (eutrophication phenomenon and production of synthetic foam) for the source of drinking water, agriculture and industrial uses in the ahvaz, iran that threaten human health. the aim of this study is the evaluation of the efficiency of the electrocoagulation (ec) process in the removal of detergent and ...

Pretreatments of low-solids potato process effluent were tested for their potential to increase surfactin yield. Pretreatments included heat, removal of starch particulates, and acid hydrolysis. Elimination of contaminating vegetative cells was necessary for surfactin production. After autoclaving, 0.40 g/L of surfactin was produced from the effluent in 72 h, vs 0.24 g/L in the purified potato ...

Effectiveness of ozonation before and after biological treatment for removal of recalcitrant organic matter in bleached kraft pulp effluents was compared. Two industrial ECF bleached eucalypt kraft pulp effluents (E1 and E2) were pretreated with 100 mg O3/L. Raw and pretreated effluents were treated biologically in bench-scale sequencing batch reactors, under constant conditions. Following biol...

There is scarcity of information on the possible mechanisms of pharmaceutical effluent induced genotoxicity and systemic toxicity. This study investigated the genotoxicity and systemic toxicity of a pharmaceutical effluent in Wistar rats. Rats were orally treated with 5-50% concentrations of the effluent for 28 days. At post-exposure, blood, liver, kidney and bone marrow cells were examined for...

Phosphorus (P) in wastes from piggeries may contribute to the eutrophication of waterways if not disposed of appropriately. Phosphorus leaching, from three soils with different P sorption characteristics (two with low P retention and one with moderate P retention) when treated with piggery effluent (with or without struvite), was investigated using batch and leaching experiments. The leaching o...

16 Grey model (GM) and artificial neural network (ANN) were employed to predict suspended solids 17 (SSeff), chemical oxygen demand (CODeff) and pHeff in the effluent from conventional activated 18 process of an industrial wastewater treatment plant using simple online monitoring parameters (pH 19 in the equalization pond effluent; pH, temperature, and dissolved oxygen in the aeration tank). Th...
