South Carolina Department of Health and Environmental Control (SCDHEC) Filter Assessment Manual

SCDHEC’s Filter Assessment Manual is a compilation of proven filter testing techniques gathered from various sources, including AWWA conference proceedings, EPA guidance manuals, and water treatment textbooks. The manual describes in detail how to conduct a filter assessment and how to establish a filter surveillance program, two activities that can and should be practiced at drinking water treatment plants to optimize filter performance. Both of these optimization activities make use of a number of physical and operational filter tests designed to pinpoint various factors that may be limiting filter performance. A filter assessment is a single event during which most or all of the different filter tests are conducted in a comprehensive, full-scale investigation of filter performance. A filter assessment is often done when poor filtered water quality indicates that there may be a problem with a filter’s physical condition or its operation. A filter surveillance program is the routine testing of filter performance on an ongoing basis, incorporating each of the various filter tests according to a set schedule. A filter surveillance program is designed to monitor filter performance and to prevent problems from occurring. The SCDHEC Filter Assessment Manual contains a description of each of the different filter tests, including setup, equipment needed, and step-by-step procedures, complete with photographs and worksheets. The manual also explains how to interpret the test results and to apply the results to corrective actions that can optimize filter performance and filtered water quality.
