Membrane Bioreactors (MBRs) bring a new age of biological waste water treatment. With pure oxygen the benefits of MBRs are enhanced resulting in even higher rate biological treatment systems which provide compact control of COD, microorganisms and VOCs in waste water.
"Oxy-Dep MBR can use high biomass concentrations, which for air-based systems cause oxygen transfer limitations. High purity oxygen resolves this, as well as the foaming and VOC issues associated with air-based systems"
