. The total suspended solids (MLSS) in the aeration basin should be > 1000 mg/L

(and less than 2,500 mg/L)

2. Effluent characteristics should meet permit: soluble COD < 30 mg/L, carbonaceous

BOD < 10 mg/L. Ammonia-nitrogen < 5 mg/L. Effluent TSS < 30 mg/L.

3. Sludge total suspended solids concentration for the primary settler should be less

than 20,000 mg/L and less than 10,000 mg/L for the waste activated sludge (WAS).
