As a part of the expansion, a better method of sludge disposal was needed or the 20 acre lagoon would soon be full.
Double Dewatering

Completion of this project will make the Broward County facility one of the five largest belt filter press dewatering facilities in the U.S.
At Their Disposal
Water & Wastes Digest
September 2003
The City of Springfield, Mass., installed a Komline-Sanderson Biosolids Drying Facility that produces a dried product having 95% solids, which could be disposed of as a Class A, exceptional quality material.

Costly, time-consuming and persistent maintenance problems, coupled with unacceptable odor levels, prompted a major southwest wastewater treatment plant to scrap its sludge handling system.
Integrated Technology Simplifies Dewatering Process at Two Municipal STPs

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.
Integrated Technology Simplifies Dewatering Process at Two Municipal STPs
Water & Wastes Digest
October 2002
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.
New Mixed Oxidant Controls Belt Press Odors
Water & Wastes Digest
February 2002
A Midwest municipality needed to find a way to eliminate hydrogen sulfide from the atmosphere in the sludge dewatering area as well as on the plant grounds. The successful elimination of noxious and toxic gas would not only make a safer, healthier environment for the workers involved but would also result in a reduction in the corrosion of metallic components in the dewatering area, while greatly reducing odor complaints from neighbors.
