  • Mathematical models for biomass in membrane-BNR process for wastewater treatment

    The equation of biomass is related to the mass-balance equation of substrate. This equation of substrate is expressed according to a model using the Monod equation, which indicates some limits for calculating the amounts of VSS in the MBR process. Some degradation of biomass which is caused by long SRT might result in the generation of substrate based on COD. Research was conducted by lab-scale ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...
