A municipal wastewater having a BOD5 of 225 mg/L is to be treated by a two-stage trickling filter. The desired effluent quality is 30 mg/L of BOD5. If both of the filter depths are to be 1.83 m and the recirculation ratio is 2:1, find the required filter diameters if both the two trickling filers have same removal efficiencies. Use NRC equation and the following design assumptions. Design assumptions: o Influent flow = 10,000 m3 /d o Recirculation ratio =...

A trickling filter plant consists of a primary sedimentation tank, a trickling filter 21 m in diameter and 2 m depth, and a secondary sedimentation tank. The primary effluent BOD is 100 mg/L, the plant final effluent is 25 mg/L and the recirculation flow is 0.5 of the wastewater flow entering the plant. The temperature of the water is 15oC. The constants for the random plastic media are n = 0.5 and   k20 = 0.055 min-1. Calculate the hydraulic loading.

Problem #3: Biochemical Oxygen Demand (BOD) and Stream Quality A wastewater treatment plant designed for a community of 45,000 people has a flow of 100 gal/person/day and a BOD5 loading of 0.2 lb/person/day. The upstream characteristics of the receiving waters are: stream flow rate = 20 cfs and BOD5 = 2 mg/L The water quality standards require the in-stream BOD5 to be less than 7 mg/L in this stretch of the river. The minimum BOD removal efficiency that the treatment...
