Methane emission during municipal wastewater treatment.
Municipal wastewater treatment plants emit methane. Since methane is a potent greenhouse gas that contributes to climate change, the abatement of the emission is necessary to achieve a more sustainable urban water management. This requires thorough knowledge of the amount of methane that is emitted from a plant, but also of the possible sources and sinks of methane on the plant. In this study, ...
متن کاملVetiver System for Wastewater Treatment
Clean water is becoming one of the most scarce and valuable resources in the twenty first century as its supply is finite and its traditional source is easily polluted by industries and population growth. Existing and traditional wastewater treatment methods are expensive and in most cases are either impractical or unsuitable for smaller communities and certain industries. The Vetiver System wa...
متن کاملDenitrification in constructed wetlands used for treatment of swine wastewater.
Constructed wetland treatment of swine wastewater probably involves substantial denitrification. Our objective was to assess denitrification and denitrification enzyme activity (DEA) in such wetlands in relation to plant communities, N loading, carbon or nitrogen limitations, and water depth. Two wetland cells each 3.6 m wide and 33.5 m long were connected in series. One set of cells was plante...
متن کاملIntegrating an intermittent aerator in a swine wastewater treatment system for land-limited conditions
A full scale swine (300 pigs) waste treatment system, including a solid/liquid separation unit (3 m) with a solids holding tank (1.2 m) and a liquid holding tank (20 m), two anaerobic reactors (10 m each) in series, an intermittent aeration unit (20 m), a sedimentation/polishing unit (20 m) and a sludge dewatering bed (17 m), was used to investigate the impact of integrating an intermittent aer...
متن کاملImprovement of Nanosized CuO-Fe2O3/cordierite System by Li2O-treatment for wastewater treatment
A mixture of 10 wt% CuO-10 wt% Fe2O3 supported on cordierite were prepared by wet impregnation. The as-prepared solids doped with Li2O (0.75-3 mol %) were calcined at 500-900 ºC. The crystalline phase, morphology, and surface area were investigated by XRD, HR-TEM and N2-adsoprtion-desorption. Moreover, their photocatalytic activities of samples calcined at 700°C on the degradation of phenol wer...
