Calculate the hydraulic loading, solids loading, polymer dosage,and solids recovery.
A belt filter press housed in a mobile trailer was used to test the dewaterability of an anaerobically digested sludge.The effective width of the belt was 0.50 m.The operating data were a sludge feed rate of 4.5m3/hr, polymer dosage of 0.45 m3/hr containing 0.20% powdered polymer by weight,and wash-water flow of 1.07 1/s.Based on laboratory analyses, total solids in the feed sludge equaled 3.5%, total solids in the cake equaled 32%, wastewater from belt washing contained 2600 mg/l suspended solids, and the filtrate was 1.20 l/s with 500 mg/l of suspended solids. Calculate the hydraulic loading, solids loading, polymer dosage,and solids recovery.
