چکیده
Abstract A continuous lab-scale integrated bio-system was conducted to treat sewage wastewater from Abu-Rawash treatment plant (WWTP). The showed high efficiency in removing chemical oxygen demand (COD), biological (BOD 5 ), and total suspended solids (TSS). experimental analysis results indicated that the maximum COD removal methane yields were 97.6 13.74 mmol CH 4 /Kg at a hydraulic retention time (HRT) of 6 h, respectively. Zn, Mn, Fe removed rate up 96.6%. sponge bio-carriers have improved overall performance substantially mixed liquor volatile solids/mixed (MLVSS/MLSS) ratio an appreciated range, pathogenic organisms 99.8% second stage. Because innovative enables rapid startup process, is simple use, inexpensive, it can provide economically feasible alternative for management could be extended full-scale applications agricultural purposes.

The Benchmark of the European group COST 624 aims to compare control strategies of activated sludge processes in Wastewater Treatment Plants. In this paper, the design of the control strategy has been oriented so as to improve the effluent quality. An accurate reduced model of the ASM1 model has been established using singular perturbations techniques. This model has been used in a sensitivity ...
متن کاملParticulate and colloidal silver in sewage effluent and sludge discharged from British wastewater treatment plants.
Differential filtration was used to measure silver (>2 nm) entering and leaving nine sewage treatment plants (STPs). The mean concentration of colloidal (2-450 nm) silver, which includes nanosilver, was found to be 12 ng L(-1) in the influent and 6 ng L(-1) in the effluent. For particulate silver (>450 nm) the mean values were 3.3 μg L(-1) for influent and 0.08 μg L(-1) for effluent. Thus, remo...
متن کاملEvaluation of Shiraz wastewater treatment plant effluent quality for agricultural irrigation by Canadian Water Quality Index (CWQI)
BACKGROUND Using treated wastewater in agriculture irrigation could be a realistic solution for the shortage of fresh water in Iran, however, it is associated with environmental and health threats; therefore, effluent quality assessment is quite necessary before use. The present study aimed to evaluate the physicochemical and microbial quality of Shiraz wastewater treatment plant effluent for b...
