Effective Wet-Weather Treatment

Effective Wet-Weather Treatment

AquaPrime from Aqua-Aerobic Systems

The idea of cloth-media filtration is nothing new for tertiary treatment. However, the technology is now available for primary treatment, as well as for assistance in high wet-weather flows.

According to Aqua-Aerobic Systems, the AquaPrime cloth-media filtration system can perform reliable primary treatment in a fraction of the footprint of conventional primary settling basins while also reducing load on biological treatment systems, according to John Dyson, the company’s AquaPrime product channel manager.

“Our technology is different from other solutions because it is based on the proven tertiary filtration solutions but combines filtration with settling of solids and floatable removal into one treatment solution,” he says. “Because of the three combined methods of solids removal, we are capable of achieving greater than 80 percent removal of TSS and 50 percent removal of BOD in primary applications without chemical addition.”

The system can be an effective solution for combined sewer overflow, sanitary sewer overflow, and stormwater applications due to its proven removal efficiencies and high-quality effluent, even under varying influent conditions. It uses a disc configuration and the OptiFiber PF-14 pile cloth filtration media to effectively filter high solids waste streams without the use of chemicals. That makes it ideal for primary wastewater treatment and wet-weather applications due to its proven removal efficiencies and high-quality effluent, even under varying influent conditions.

“It actually treats excess wet-weather flows by splitting flow around primary/secondary processes, then blending the secondary clarifier effluent with the raw wastewater to achieve low level TSS and BOD effluent,” Dyson says.

The system’s three zones of solids removal include floatable, settled solids and filtration zones to effectively filter wet-weather flows with or without the use of chemicals. The system’s flexibility allows for dual use for tertiary and/or wet-weather treatment based on a facility’s daily treatment needs. According to Dyson, several years of research and development went into this sustainable treatment solution.

“The AquaPrime was in development and testing for 4 1/2 years before it was introduced to the market at the end of 2016,” he says. “The technology is specifically developed to provided advanced primary treatment, which is targeted to the trend of wastewater facilities to be green, sustainable and energy neutral. Advanced primary treatment provides reduced solids and carbon to the secondary process resulting lower aeration and reduced energy cost.”
