Conventional Activated Sludge, BOD, Sewage, Aeration period, Sludge Retention Time and Return Sludge Ratio.



Carrying out a design on a conventional Activated Sludge Plant under several conditions and various criteria is becoming complex, tedious and cumbersome. The era of Computer has resulted in a faster, accurate, and more advanced method of obtaining data, storage, processing and analysis. Several tools are being developed to design and solve various engineering problems and environmental engineering field is no exception. Some packages have been developed in this area in basic, C - language, visual basic etc. This research focuses on the full design of a conventional Activated Sludge Plant. Some of the components developed include: Daily Sewage Flow, BOD of Sewage entering the aeration, BOD left in Effluent, BOD removed in Activated Plant, Efficiency required in Activated Plant, Rate of air supply, secondary sedimentation tank and Sludge drying beds. Design for the checks was also developed. Some of the checks include: Aeration Period, Sludge Retention Time, Volumetric Loading and Return Sludge Ratio. Visual Basic Package was adopted for the design.
