Microbial electrolysis cells (MECs) can be used to treat wastewater and produce hydrogen gas, but low cost cathode catalysts are needed to make this approach economical. Molybdenum disulfide (MoS2) and stainless steel (SS) were evaluated as alternative cathode catalysts to platinum (Pt) in terms of treatment efficiency and energy recovery using actual wastewaters. Two different types of wastewa...

Currant Creek, a second order stream in southwestern Wyoming, has three large complexes of beaver ponds midway along its 32 km length. To determine whether these ponds improve the quality of water flowing through them, during spring and summer of 1984 and 1985 water samples were taken upstream from, within, and downstream from the pond complexes. During periods of high flow (i.e. spring runoff)...

Background Peripheral blood flow is increased by blackcurrant intake in humans [1], potentially by anthocyanin-induced vasorelaxation and vasodilation [2], which may affect substrate delivery, exercise performance and recovery. We examined the effect of 1-week CurraNZ blackcurrant on substrate oxidation during steady state cycling, 16.1 km (10 mile) time-trial performance and lactate clearance ...

BACKGROUND, AIM, AND SCOPE Fishery wastewater treatment can be compromised due to seasonal production. The use of sequencing batch reactors is not completely successful, despite flexibility being one of the principal advantages. Most research on activated sludge is performed using synthetic wastewater to ensure a stable and constant feed. The current work compared biomass morphology and settlin...

The gender empowerment of communities and individuals in Ein Qinia village / Ramallah on the acceptance of wastewater treatment projects and treated wastewater reuse was studied. The gender acceptance was determined through whether or not trained focused women groups in treated wastewater reuse could be increased in reusing the treated wastewater in agricultural activities. Women showed a high ...

Radiation processing was found effective in wastewater purification and disinfection, and has been investigated in many countries through laboratory scale and pilot scale facilities. This technology can be applied to the treatment of industrial wastewater from textile dyeing industries, papermill and petrochemical processes, and also for the reclamation of effluent from municipal wastewater tre...

The energy content of wastewater is routinely assessed by chemical oxygen demand (COD) measurements that only provide an incomplete picture and the data fundament of other energy parameters remains scarce. The volumetric heat of combustion (ΔCH) of raw wastewater from a municipal wastewater treatment plant (WWTP) was assessed using oven drying method (ΔCHvol = −6.8 ± 4.3 kJ L, n = 20) and freez...

The risk of Giardia duodenalis (Giardia) infection in farmers using untreated wastewater in agriculture was investigated in the city of Faisalabad, Pakistan, through a cross-sectional study. The study found a significantly increased risk of (asymptomatic) Giardia infection in wastewater farming households when compared with farming households using regular (non-wastewater) irrigation water (OR ...

Life Cycle Assessment has been used to compare different scenarios involving wastewater reuse, with special focus on toxicity-related impact categories. The study is based on bench-scale experiments applying ozone and ozone in combination with hydrogen peroxide to a wastewater effluent from a Spanish sewage treatment plant. Two alternative characterisation models have been used to account for t...
