Environmental assessment of two small scale wastewater treatment systems: SBR vs CAS
European Water Directive 91/271/EEC introduced a series of measures aimed at protecting sensitive areas against the emission of nutrients originating from waste water treatment plants. There are, however, environmental costs associated with achieving the required level of water quality, such as greenhouse gas emissions resulting from energy consumption. The goal of this study is to assess ...

Low temperature biological phosphorus removal and partial nitrification in a pilot sequencing batch reactor system
Partial nitrification and biological phosphorus removal appear to hold promise of a cost-effective and sustainable biological nutrient removal process. Pilot sequencing batch reactors (SBRs) were operated under anaerobic/aerobic configuration for 8 months. It was found that biological phosphorus removal can be achieved in an SBR system, along with the partial nitrification process. Sufficient ...

Nutrient removal, microbial community and sludge settlement in anaerobic/aerobic sequencing batch reactors without enhanced biological phosphorus removal
Nutrient removal, microbial community and sludge settlement were examined in two 3-litre laboratory-scale anaerobic/aerobic sequencing batch reactors (SBRs). One SBR was operated at 10°C and the other SBR at 20°C. Different from conventional enhanced biological phosphorus removal, most of the soluble sodium acetate was removed in the aerobic phase and no organic carbon uptake or biological ...
