Notes on Activated Sludge Process Control Page 26 Example: Calculate the total solids production (accumulation) in an extended aeration plant. Given: TSS = 100 lbs/day VSS = 85 lbs/day BOD = 100 lbs/day Solution: Accumulation = net growth + inert + nonbiodegradable Example: Calculate the total solids production (accumulation) in a high rate plant.
Types of Activated Sludge Process Conventional aeration. In conventional ASP the flow model in aeration tank is plug flow type. Boththe influent wastewater and recycled sludge enter at the head of the tank and are aerated for about 5 to 6 hours for sewage treatment (Figure ). The influent and recycled sludge are mixed by the
It is a relatively recent addition in the wastewater treatment field. Combining an aeration tank with membrane filtration instead of a secondary clarifier, results in a more compact system than conventional activated sludge that produces a higher quality effluent.

This Activated Sludge Training Manual was prepared by the Michigan Department of Environmental Quality, Operator Training staff. It is intended to be used as an aid in the presentation of the MDEQ Activated Sludge Process Control Training Course, along with numerous handouts, class discussion, and an abundance of slides.
Conventional activated sludge with full BNR will be incorporated at the 75th Street Wastewater Treatment Plant (WWTP) in two phases. BNR will include both nitrogen and phosphorous removal capacity. Phase 1 will provide nitrogen removal capacity via nitrification and denitrification; while
Activated sludge wastewater treatment calculations can be made using the Excel formulas in the downloadable spreadsheets. Biochemical oxygen demand (BOD), waste water flow rates and total suspended solids concentrations are used in the activated sludge calculations

To the Graduate Council: I am submitting herewith a dissertation written by Jinsheng Huo entitled "Application of Statistical Methods and Process Models for the Design and Analysis of Activated Sludge Wastewater Treatment
The results of analyses for time dependent characteristics of the activated sludge process showed interesting, but not conclusive trends, The ability of the activated sludge process to minimize variations in influent streams was demonstrated, but equipment failure, poor oper ating conditions and lack of time prevented an indept analysis.
