Filtration system to improve operations of WA city's WWTP

Sponsored by


CARY, NC, Dec. 20, 2013 -- As part of a recent contract, the wastewater treatment facility in Camas, Wash., will receive new filtration systems as part of the area's Phase 2B improvements project.

Provided by Kruger Inc., a subsidiary of Veolia Water Solutions & Technologies, two Hydrotech Discfilter units along with a controls system will replace the facility's current cloth media filtration system. Further, the technology is designed to filter a peak flow of 6.0 MGD and provide an effluent total suspended solids (TSS) concentration of ≤10 mg/L. 

The Hydrotech Discfilter system employs woven cloth filter elements installed on multiple discs and utilizes an inside-out flow pattern, providing a large filtration area with a small footprint. Likewise, the filter is ideal for effluent polishing from a number of process trains, including activated sludge, high-rate clarification, MBBR, RBC, and trickling filters, and is used to produce reuse-quality effluent and achieve phosphorus concentrations of <0.1 mg/L.

Kruger's Hydrotech Discfilter system's compact footprint will allow it to be installed within the footprint of the Camas facility's existing cloth media filtration system. The new Discfilter system is expected to be operational by the end of 2013.
