Status of Porous Biomass Support Systems for Wastewater Treatment: An Innovative/Alternative Technology Assessment

摘要

A study was conducted to assess the emerging wastewater treatment technology of porous biomass support systems (PBSS). These systems use large numbers of small, open-cell or reticulated polyurethane foam pads to support high concentrations of biomass in an aeration basin. Visits were made to laboratories of the original process developers in the United Kingdom and in West Germany. The study concluded that PBSS technology does not presently qualify as a fully developed technology, but that the technology offers some attractive potential benefits and very little risk for some intended applications.
