The 21st century offers many challenges to every one of us. As more firms go global, as more economies interconnect, and as the Web blasts away boundaries to communication, we….
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.
