Determine the dimensions of a high rate trickling filter for the following data: (ii) Recirculation ratio = 1.5 (iv) BOD removed in primary tank = 25%. (i) Sewage flow = 3.0 MLD (iii) BOD of raw sewage = 250 mg/L (v) Final effluent BOD desired = 30 mg/L By what % the diameter of the filter will have to be modified if it is to be designed as a standard rate trickling filter for the above requirement.

Determine the dimensions of a high rate trickling filter for the following data:
(ii) Recirculation ratio = 1.5
(iv) BOD removed in primary tank = 25%.
(i) Sewage flow = 3.0 MLD
(iii) BOD of raw sewage = 250 mg/L
(v) Final effluent BOD desired = 30 mg/L
By what % the diameter of the filter will have to be modified if it is to be designed as a standard
rate trickling filter for the above requirement.
