Application of biological aerobic filter for industrial wastewater recover and reuse

The Biological Aerated Filter(BAF)has many advantages,such as small volume high treatment efficiency etc.The studies show that the performance of BAF for sewage treatment is excellent.Under the hydraulicrate of 240 m~3/d and HRT of 3 h,the average removal percent for COD,BOD and SS is high enough to reach the water quality standard for urban water consumption,which can be reused.
