11.29.23 -- Maintaining Greater Value In Bar Screen Performance

Before wastewater can be treated to minimize biochemical oxygen demand (BOD), nutrients, and pathogens, it is important to eliminate as much debris as practical, as early in the treatment plant as possible, to avoid clogging pumps or compromising downstream performance. Careful consideration of design and operating factors can minimize total lifecycle costs and maintenance effort while protecting screening efficiency.

There’s a lot to be said for the old adage, “Use the right tool for the job.” When it comes to flow meters for municipal or industrial water treatment plant (WTP) and wastewater treatment plant (WWTP) operations, however, the sheer number of choices can be overwhelming. That is where using a process of elimination to winnow out styles that don’t fit the performance criteria of an application can make it easier to compare the few remaining options. Here is a checklist of considerations to accelerate that process.

The pumps at the septage receiving wet well at the Valley Forge Sewer Authority’s collection system were constantly clogging -- creating frequent headaches for the operators and costing valuable time and expenses.

Circa 2010, Carollo Engineering designed and implemented expansions at wastewater treatment plants in Delano, CA, and Reedley, CA, to handle increased flows of up to 8.8 MGD and 5.0 MGD, respectively. The proposals for both facilities specified a need for storage and processing of secondary sludge produced by the processes’ secondary clarifiers. Mazzei Injectors were selected to provide an efficient, zero maintenance method of freshening and mixing the sludge. Read the full case study to learn more.

A Pennsylvania treatment plant upgraded its headworks to an innovative grit removal system that handles combined sewer storm surges, removes fine grit particles, and lessens maintenance on operations staff.

Los Alamos, NM, the former site of top secret laboratories where government scientists developed the atomic bomb during World War II, is once again a town at the forefront of new technology.
