The borough of West Mifflin, Penn., is a community located about nine miles southeast of downtown Pittsburgh. For years, the West Mifflin Sanitary Sewer Municipal Authority (WMSSMA) hauled liquid from its New England STP (a 1.2 mgd plant) to the Thompson Run facility (a 4.5 mgd plant), where it was processed on a belt press for dewatering. However, the hauling and associated labor proved very costly, and it was not always easy to coordinate dewatering schedules for both plants.
Additionally in the late 1990s, the WMSSMA faced a requirement to achieve higher cake solids and provide odor control that would respect nearby homes and businesses. Moreover, space constraints and staffing reductions necessitated a simple-to-operate installation.

In the late 1990s, one western Pennsylvania sewage treatment plant (STP) sought to process Class B biosolids on-site, eliminating the expense of hauling liquid off-site and significantly decreasing associated labor costs. At the same time, the plant needed to achieve higher cake solids and provide strict odor control. In addition, the selected equipment also had to be able to greatly enhance process efficiencies at not just the one plant, but its sister facility as well. Fortunately, USFilter offered a fairly simple solution to meet the STP's seemingly complex needs.
