Secondary Treatment Based on a plant flow rate of 40 mgd, design an activated sludge, secondary treatment system with recycle which maintains a MLVSS = 2,000 mg/L in the aeration reactor and has an average Solids Retention Time (SRT) = 4 days. The biota kinetic constants are: Kinetic Coefficients for the Activated-sludge Process for the Removal of Organic Matter from Domestic Wastewater - Endogenous Decay Coefficient – k(d) Half-velocity constant – K(s) 0.1 15 Max.
