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...
Although membrane bioreactor (MBR) systems provide better removal of pathogens compared to conventional activated sludge processes, they do not achieve total log removal. The present study examines two MBR systems treating municipal wastewater, one a full-scale MBR plant and the other a lab-scale anaerobic MBR. Both of these systems were operated using microfiltration (MF) polymeric membranes. ...
This paper employs the discrete choice experiment method to estimate the benefits of improved wastewater treatment programs to mitigate the impacts of water pollution in Nairobi, Kenya. Urban and peri-urban farmers who use wastewater for irrigation from Motoine to Ngong River in Nairobi were randomly selected for the study. A random parameter logit model was used to estimate the individual leve...
Nutrients and water found in domestic treated wastewater are valuable and can be reutilized in urban agriculture as a potential strategy to provide communities with access to fresh produce. In this paper, this proposition is examined by conducting a field study in the rapidly developing city of Hyderabad, India. Urban agriculture trade-offs in water use, energy use and GHG emissions, nutrient u...
