Keeping Odor Under Control   Water & Wastes Digest August 2005   By Ed Sullivan
“We are very concerned about maintaining an odor cap,” said David Williams, project engineer at Shell Oil (Shell Manufacturing) Martinez Refinery, California “Our treatment pond is about 1/4 mile from a residential community. We’ve got a delicate situation where even just a slight amount of odor could arouse complaints from the community. So, we keep a close eye on it.”

Winds Can Produce a Malodor Malady   Water & Wastes Digest September 2003   Anthony J. Sadar
Odor-minimization practices can reduce your facility's chance of emitting offensive odors beyond its borders. By implementing odor-minimization techniques, careful siting and construction of potential odor-producing sources, and the use, when necessary, of odor controls, your plant can successfully minimize malodors and keep its good-neighbor status.

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.

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.

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.
