Full Description

Cost-effective integration of low-pressure membrane filtration systems into existing large watertreatment facilities depends upon many site-specific goals and constraints, but there are severalkey issues that generally apply. This paper reviews several of these key issues in the context of aproject that will integrate a 60-million-gallons-a-day (mgd) submerged ultrafiltration (UF)membrane system into the existing treatment processes at the Racine Water Utility (RWU). Thisproject, currently under construction, will be achieved at a total project cost of less than $0.40/galof capacity, one of the lowest unit costs to date in the industry.Five examples of key issues in the cost-effective implementation of the submerged membranesystem at Racine include the following:preliminary screening of proprietary membrane systems;reuse of existing facilities;customization of membrane system and equipment;cost-conscious design to meet regulatory and redundancy requirements; and,well-designed membrane system procurement process.The methods by which these issues were utilized for the benefit of a cost effectiveimplementation at RWU are discussed in detail. Includes tables, figure.
