  • China: Carp yields double with aeration

    In the mid-1980’s, the People’s Republic of China looked at semi-intensive cultivation to produce higher yields to provide a protein staple for its people and as an export product. Two government farms in Yunnan Province raising freshwater grass carp Ctenopharyngodon Idellus experimented with aeration. Production yields doubled from 200 kg per 0.06 ha to 500 kg at one farm with AIRE-O2® aerators. ...

  • Aerators Enhance Aerobic Digestion Process

    The city of Eden,N.C.,operates an extended aeration process designed for an average flow rate of 13.5 mgd with a mixed liquor suspended solids concentration that typically checks in about 6,000 mg/l. This high biomass concentration is necessary to provide a well-settling sludge and good effluent quality. Further, the plant influent is approximately 40% domestic wastewater and 60% industrial ...

  • Effects of C/N ratio on nitrous oxide production from nitrification in a laboratory-scale biological aerated filter reactor

    Emission of nitrous oxide (N2O) during biological wastewater treatment is of growing concern. This paper reports findings of the effects of carbon/nitrogen (C/N) ratio on N2O production rates in a laboratory-scale biological aerated filter (BAF) reactor, focusing on the biofilm during nitrification. Polymerase chain reaction–denaturing gradient gel electrophoresis (PCR-DGGE) and ...
