Photochemical reactor modeling: a case-study problem. Although radiation is important in heat transfer, an analogous model can be used in the design of photochemical reactors. The modeling of these reactors….
Determine the belt width (m) of a belt filter press (BFP) if the BFP produces a sludge cake of 22% solids.
An activated sludge WWTP produces an average of 100,000 gallons per day of primary sludge at 5% solids and 250,000 gallons per day of WAS at 1.1% solids. If the WAS is thickened to 6.0% solids by dissolved air flotation and then combined with the primary sludge prior to dewatering, what is the quantity (lb/d) and solids concentration of the blended sludge (% solids)? Determine the belt width (m) of a belt filter press (BFP) if the BFP produces a sludge cake of 22% solids. Assume that the BFP operates 5 days a week for 8 hours each day. The solids in the filtrate is assumed to be 1,800 mg/L and the addition of polymer for conditioning contributes negligible weight. Assume a washwater rate of 25 gpm/meter of belt and hydraulic loading rate = 45 gpm/meter of belt.
