A Method to Reduce Sludge Generation in Wastewater Treatment Systems

The systems and methods described provide for reducing sludge generation, and thus sludge wasting and handling, by including an anaerobic completely stirred tank reactor (CSTR) as a bioreactor in a side-stream. The CSTR provides a significant simplification of side-stream treatment design, enhanced sludge minimization, and enhanced removal of nitrogen and phosphorous without the need to add organic carbon. The described systems and methods provide generation of biogas including both hydrogen and methane from the activated sludge system. The described systems and methods avoid complex reactor designs for nutrient removal.
