The risk of human hookworm infections from land application of wastewater matrices could be high in regions with high hookworm prevalence. A rapid, sensitive and specific hookworm detection method from wastewater matrices is required in order to assess human health risks. Currently available methods used to identify hookworm ova to the species level are time consuming and lack accuracy. In this...

In order to evaluate the efficacy of constructed wetlands for treatment of domestic wastewater for small communities located in rural areas, small-scale wetland mesocosms (400 L each) containing two treatment designs (a mixture of Typha, Scirpus, and Juncus species; control without vegetation) were planted into two depths (45 or 60 cm) with pea gravel. Each mesocosm received 19 L/day of primary...

This research investigation was aimed at demonstrating the performance evaluation of pilot activated sludge treatment system (biosimulator; model MF-114). An intensive analytical program was followed for evaluating the performance efficiency of the biosimulator by maintaining the dissolved oxygen (DO) concentration at 4.0 mg/L throughout the study period. Biosimulator performance was evaluated ...

Treatment of textile wastewater with domestic as co-substrate was investigated in this study. Combined and at different mixing ratios (100:0, 80:20, 60:40) treated under anaerobic reactor. The influence residence time, fraction initial pH were determined view COD color removal. Response Surface methodology (RSM) Box–Behnken design (BBD) employed to determine conditions for higher simultaneous r...

BACKGROUND Under scarcity of freshwater, the reuse and low-cost technological solutions applied to wastewaters seek reduce contamination users freshwater biota. RESULTS A cellulose membrane was doped with silver nanoparticles filter urban wastewater (UW) from a city in Argentina. The total amount coliforms Escherichia coli decreased by 99.6% 99.9%, respectively. leak 275 ng L?1, analyzed square...

Background : Pseudomonus stutzeri bactrerium is one of the most important and effective denitrifier bacteria in wastewater. With regard to the importance of effects of nitrate on water resources and human health and role of metronidazole inhibition, this study was done with the aim of survey of effect of metronidazole different concentrations on biological denitrification of Pesudomonas stutzer...

BACKGROUND In this study, a hybrid treatment system (Fluidized Bed positioned in a biological reactor of an Activated Sludge process) was used to treat saline domestic wastewater. The performance of the mentioned hybrid system was compared with the conventional activated sludge. A pilot study was conducted, and Chemical Oxygen Demand (COD), Electrical Conductivity (EC), Total Dissolved Solids (...
