M-Defanox – multisludge system of nutrient removal

Summary

M-Defanox new technology was developed for the treatment of municipal wastewater low in organics. The method is based on the use of three sludge types and dephosphorization under anoxic conditions. The technology provides for the efficient utilization of organics in biological treatment process and ensures 99% nitrogen removal, 80% phosphorus elimination, 80% COD removal and 95% BOD removal.
