Question

Calculate the values of kf and influent bod (so) to trickling filter for r/q (ratio of recycle flow rate to hydraulic loading) value of 1.65. Given that: raw settled bod after primary settling (sa)=220 mg/l; hydraulic loading (q)=30 m3/(d. M2); depth of filter (d)=1.5 m; n=0.5 and effluent bod after secondary settling (s)=35 mg/l.
