A trickling filter plant treats 1500 m³/day of sewage with a BOD, of 220 mg/l and a suspended solid concentration of 250 mg/l. Estimate the total solid production assuming that primary clarification removes 30% of BOD and 60% of influent solids. Take the solid production in the trickling filter at 0.5 kg per kg of the applied BOD.

Mechanical Processes

In civil engineering, the materials have to undergo a series of manufacturing processes before using them in construction and structural applications. These manufacturing processes form the foundation stone of mechanical processes. Some of the civil engineering materials such as bars, metallic beams, metallic columns, surveying equipment, earthmovers, overhead cranes, structural and construction components, and even cement that is the most fundamental construction component need to undergo different manufacturing processes before they are ready to use. These processes are mechanical.

Question

A trickling filter plant treats 1500 m³/day of sewage with
a BOD, of 220 mg/l and a suspended solid concentration
of 250 mg/l. Estimate the total solid production assuming
that primary clarification removes 30% of BOD and 60%
of influent solids. Take the solid production in the trickling
filter at 0.5 kg per kg of the applied BOD.

As an operator of a wastewater treatment facility, you have learned that your plant runs well at an SRT (based on MLVSS (X) in the aeration basin) of 12 days. If today’s MLVSS (X) concentration is 2,700 mg/L and the RAS (Xr) concentration is 5,500 mg/L, how many L of sludge should you waste from the secondary clarifier today? Other design conditions: Average influent flow = 12,000 m3/d Influent soluble BOD = 150 mg/L Required effluent TSS = 30 mg/L Aeration tank Volume = 1,000 m3
