Dear sir,anyway we are working in A2/O also.It is necessary to introduce nitrogen and phosphorus removal processes in the wastewater treatment plants to improve the water quality . An A2/O (anaerobic-anoxic-oxic) process using immobilized media is proposed here, as a high-end technology to meet stricter discharge standards when faced with treatment space limitations. Fluidized immobilization media were added to the aerobic reactor to maintain a high concentration of nitrifying bacteria and nitrification rate. The process performs well for removal of nitrogen and phosphorus under the condition of HRT = 8 hr, it was possible to obtain an effluent water quality as follows: T-N<8.0 mg/L; T-P<1.0 mg/L.Flow chart1.3 Q return from AerobiclQ In--- Anaerobic--Anoxic---Aerobic--Settling--- Outl0.5 Q Return From SettlingA2/o process is basically adding of Anoxic zone between Anaerobic and aerobic .
