Floating treatment wetlands for domestic wastewater treatment.
Floating islands are a form of treatment wetland characterized by a mat of synthetic matrix at the water surface into which macrophytes can be planted and through which water passes. We evaluated two matrix materials for treating domestic wastewater, recycled plastic and recycled carpet fibers, for chemical oxygen demand (COD) and nitrogen removal. These materials were compared to pea gravel or...
متن کاملCiprofloxacin Resistance in Domestic Wastewater Treatment Plants
The potential of domestic wastewater treatment plants to contribute for the dissemination of ciprofloxacin-resistant bacteria was assessed. Differences on bacterial counts and percentage of resistance in the raw wastewater could not be explained on basis of the size of the plant or demographic characteristics of population served. In contrast, the treated effluent of the larger plants had signi...
متن کاملCharacterization and assessment of "Kullar Domestic Wastewater Treatment Plant" wastewaters.
We investigated conventional characterization of wastewaters of the "Kullar Domestic Wastewater Treatment Plant." In the study of conventional characterization; 23 composite samples, which were taken during 10 months, were used and analysed as COD, BOD5, TKN, NH3-N, SS, VSS, TP, RP, TS, Alkalinity, oil and grease, detergent, chloride parameters. For determine of the plant efficiency, 8 output g...
متن کاملAnaerobic treatment of domestic wastewater in subtropical regions
Seghezzo, L. (2004), Anaerobic treatment of domestic wastewater in subtropical regions, Ph.D. thesis, Wageningen University, Wageningen, the Netherlands. In this thesis, the use of upflow anaerobic sludge bed (UASB) reactors for sewage treatment was studied in the city of Salta, northwestern Argentina. The climate in this region can be defined as subtropical with a dry season. Mean ambient temp...
متن کاملSludge granulation during anaerobic treatment of pre-hydrolysed domestic wastewater
The aim of this study was to examine sludge granulation during the anaerobic treatment of pre-hydrolysed municipal wastewater. The pretreated wastewater had a total chemical oxygen demand (CODt) of 432 ± 20 mg/l, a soluble COD (CODs) of 259 ± 8 mg/l, volatile fatty acids (VFA) of 101 ± 9 mg/l and suspended solids (SS) of 94 ± 12 mg/l. Prior to entering the digester, the influent was supplemente...
