  • Bioaugmentation In Sewer Network Reduces Sludge Production

    This article describes the effectiveness of bioaugmentation in the sewer network as a strategy to reduce sludge production. Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing ...

  • Bioaugmentation in Sewer network reduces sludge production case study

    Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing municipal plants.

  • The Use of Oxidation-Reduction Potential as a Means of Controlling Effluent Ammonia Concentration in an Extended Aeration Activated Sludge System

    ABSTRACTThis study developed a strategy to control effluent ammonia from an activated sludge system, using oxidation-reduction potential. By controlling effluent ammonia concentrations, disinfection of treated wastewater is more cost effectively achieved by chloramination rather than break-point chlorination. The system under consideration was an extended aeration oxidation ditch. The study takes ...
