Cost-effective integration of low-pressure membrane filtration systems into existing large water
treatment facilities depends upon many site-specific goals and constraints, but there are several
key issues that generally apply. This paper reviews several of these key issues in the context of a
project 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). This
project, currently under construction, will be achieved at a total project cost of less than $0.40/gal
of 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 membrane
system 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 effective
implementation at RWU are discussed in detail. Includes tables, figure.
