Carbon recovery from screenings for energy-efficient wastewater treatment
The energy content of screenings from six municipal wastewater treatment plants (WWTPs) was examined. Hourly samples of separated screenings were taken over 24 hours at three of the plants to illustrate diurnal variations. To recover the chemical energy, which usually leaves the WWTP with the screenings, a screenings wash press was used to transfer organic matter from the solid into the ...

An adaptive, comprehensive monitoring strategy for chemicals of emerging concern (CECs) in California's aquatic ecosystems
A scientific advisory panel was convened by the State of California to recommend monitoring for chemicals of emerging concern (CECs) in aquatic systems that receive discharge of municipal wastewater treatment plant (WWTP) effluent and storm water runoff. The panel developed a risk‐based, screening framework that considered environmental sources and fate of CECs observed in receiving waters ...

Assessment of hormonal activities and genotoxicity of industrial effluents using in vitro bioassays combined with chemical analysis
Wastewaters from various industries are a main source of the contaminants in aquatic environments. The authors evaluated the hormonal activities (estrogenic/anti‐estrogenic activities, androgenic/anti‐androgenic activities) and genotoxicity of various effluents from textile and dyeing plants, electronic and electroplate factories, pulp and paper mills, fine chemical factories, and municipal ...
