WesTech Engineering, through its subsidiary WWETCO, was selected by Black & Veatch and the City of Springfield, Ohio, to design and manufacture the largest compressible media filter in the world.

Installation of 100 mgd WWETCO FlexFilter will begin at the Springfield Wastewater Treatment Plant in 2013. The filter will contain nearly 20,000 cubic feet of compressible media and will be used 20 to 30 times a year as part of a high-rate treatment (HRT) facility to treat CSO events.

The process will extend the plant’s performance capability so that CSO flows will not have to be bypassed. That will enhance the environmental health of the Mad River.

The city selected the FlexFilter because the design requires very little operator attention or maintenance,” said John Gottschall, general manager and vice president of WWETCO. “Plant operators have enough to do during high-flow events. They want a technology they can rely upon. The FlexFilter requires no chemical use and produces a high quality effluent at 85 percent solids removal or better.”
