Page 5: System Description
Sign: GS System description The JOWA STP 2010 is an aerated, submerged, fixed-film unit with a proprietary aeration system that provides major advantages for the operator. The raw sewage is led to the pre-bioreactor chamber. In the pre-bioreactor chamber non biodegradable solids are screened and settled for later discharge. - Page 6 STP 2010 Series Sign: GS Due to the high degrading power of the JOWA STP 2010, they are much smaller than comparable biological degradation methods using suspended growth (rather than fixed-film) systems. In addition, because the Bioreactor is a submerged, fixed-film unit, the biomass is more stable and able to tolerate both hydraulic and organic shock loadings better than the alternatives.
