Addressing the Challenge of Removing Ammonia from Wastewater
WebAn activated sludge system has a flow of 5000 m3/day with X = 4000 mg/L and S0 = 300 mg/L. From pilot plant work the kinetic constants are Y =0.5, μˆ =3 d−1, KS =200 mg/L. We need to design an aeration system that will determine the (a) the volume of the aeration tank; (b) the sludge age; (c) the amount of waste activated sludge. 95% BOD ...
