Integrated Technology Simplifies Dewatering Process at Two Municipal STPs   Water & Wastes Digest February 2003   Robert W. Mau, USFilter
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.

Odor Control System   Water & Wastes Digest January 2003   Brent Howe
Odor complaints have become an all too familiar subject to WWTP managers. They are not only expected to manage their plants effectively and efficiently, meeting both regulatory specs and budget requirements – they are also expected to be good neighbors and keep odor under control. This article describes the successful odor control efforts of the South Dearborn Regional Sewer District located in Lawrenceburg, Ind.

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.

Ohio Wastewater Treatment Plant Installs Covers On Sludge Digester Tanks   Water & Wastes Digest January 2001
Attempting to maintain aerobic conditions in two large, municipal thickened sludge digesters created problems in an Ohio community. High aeration rates caused splashing out of the digesters, while lowering the aeration rates to reduce the splashing created additional odors.

Pump Upgrade Solves Odor Problem at Texas Lift Station   Water & Wastes Digest September 2000
Threatened by a stench-driven lawsuit several years ago, the city of Rockport, Texas, decided to convert the last of its three dozen lift stations to submersible pumps. Today, with the problem resolved, significant benefits have accrued. The odors have dissipated, the nearby residents and business people are breathing comfortably, and the sewer system is operating more efficiently.

Dairy Farmers Having Success Piping Animal Waste to Lagoons   Water Engineering & Management August 2000
Two dairy farmers have found similar success using animal waste lagoons to protect groundwater and cut overhead. For one of these farmers, recycling the herd’s waste has even led to another farm-based business.

Hydrogen Sulfide Control in Wastewater Collection Systems   Water Engineering & Management August 2000   Tony Palmer, Paul Lagasse and Maureen Ross
When most environmental professionals think about hydrogen sulfide control in their wastewater collection systems, they are concerned with odor and corrosion. Instrumentation is now available to measure sulfides online, providing the opportunity to optimize the chemical dosage and monitor sulfide control.
