Activated Sludge-Unified System Design and Operation

Abstract

A unique procedure for designing and operating the activated sludge aeration basin/clarifier system is developed using the settling flux approach. A least-coast design procedure, utilizing batch settling tests and the state point concept, produces a design solution which minimizes capital and operational costs. In addition, the settling flux approach provides the plant operator with a tool for control and operation of the clarifer/thickener to improve treatment efficiencies and prevent operational failures.
