Design for Complete Mixing / Circulating Plug Flow Annular A~2O Process

The complete mixing-circulating plug flow A~2O process is able to treat effectively municipal wastewater and meets the demands for removal of organics, nitrogen and phosphorus. In combination with the characteristics of oxidation ditch and conventional A~2O process, the process optimizes the reaction mechanism, and improves the volumetric utilization rate and resistance to shock loading, with steady in operation and convenience in management. It is of great value in application for municipal wastewater treatment.
