Part of: Critical Issues in Water and Wastewater Treatment
Abstract: Only in the past few years has any attention been allocated to the transport characteristics of sludge collectors. However, no attention has been given to a design rationale for the sludge hopper. The configuration of a sludge hopper effects clarifier performance and restriction in the sludge removal zone causes a response similar to scraper deficiencies. Further, the design practice is obsolete as it was developed at clarifier solids loadings 30-50% of current MLSS designs for advanced wastewater treatment. This paper provides a set of guidelines for hopper design and placement based on the projected sludge flow profiles within the sludge removal zone.
