 A river water treatment plant coagulates raw water having a turbidity of 12 units with an alum dosage of 40 mg/l.

(a) Estimate the total sludge solids production in lb/mil gal of water processed,


(b) Compute the volumes of waste from the settling basins and filter backwash water, assuming that 70% of the total solids are removed in sedimentation and 30% in filtration, the settled sludge solids concentration is 1.2%, and the solids content is 600 mg/l in the filter wash water,


(c) Calculate the composite sludge volume after the two wastes arc gravity thickened to 3.5% solids.
