Aerobic treatment of dairy wastewater

  • Herbert H. P. Fang
Bioreactor Performance


Wastewater from a dairy plant with an average BOD5 of 1060 mg/l and an average TKN of 109 mg/l was treated aerobically using three activated sludge reactors in series. With an overall retention time of 19.8 hrs, the final effluent contained 9 mg/l of BOD5 and 10 mg/l of TKN, corresponding to respective reductions of 99% and 91%.
