ABSTRACT:
An apparatus and method are provided that are useful in a process for treating organic wastewater for the removal of phosphorus and nitrogen compounds. The apparatus includes an anoxic zone, an oxic zone, and an anaerobic treatment zone, each having therein microorganisms that are operable to affect biological denitrification, BOD oxidation, luxury-uptake of phosphorus and formation of nitrates.
