Bioreactor Tanks

High volume and small footprint solves many site constraints.

Small Tanks, Large Loadings. Bioreactor tank sizes can be minimized by operating at high MLSS concentrations. Compared to conventional systems, a Hi-Rate MBR System requires about 1/3 to 1/4 of the volume of reactor to handle equal organic loadings. The combination of deep water level and minimum water level equals to the small tank footprint in the smallest of all the major wastewater processes. In addition, tanks running at high MLSS concentrations are capable of processing higher organic loadings. This allows the Hi-Rate MBR System to process high volumes of treatment within awkward or restrictive site constraints.

Efficient Breakdown of Solids.

  • Solids are continually maintained in the bioreactor, so bacteria break down even recalcitrant organics due to long SRTs.
  • Sludge generation is minimized by low F/M ratios.
  • Blowers provide oxygen to bacteria to meet high uptake rates in high MLSS concentrations, minimizing tank volume compared to conventional treatment.
  • Coarse bubble aeration provides easy commercial maintenance while jet aeration provides high efficiency aeration and mixing for power savings in industrial applications.
