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 diameter (ft) of the high-rate trickling filter system.
A two-stage high-rate trickling filter with 200% recycle will be used to treat 5.0 million gallons per day (MGD). The influent BOD to the primary clarifier is 225 mg/L and the primary removes 30% of the incoming BOD. The effluent BOD should be 20 mg/L or less. Assume that the design BOD loading to the trickling filter system is 40 lb BOD/(d⋅1,000 ft3) and a depth of 6 ft will be used. Use the NRC equations for designing the trickling filter system, and assume that there are two treatment trains operating in parallel. Determine:
a. The diameter (ft) of the high-rate trickling filter system.
b. The effluent BOD concentration (mg/L).
