New Filtration Technology: WWETCO Compressible Media FlexFilter Gaining Momentum

WWETCO, LLC of Canton, GA is commissioning their recently installed WWETCO FlexFilter™ system for the current wastewater system improvements for the City of Lamar, Missouri. This compressible media filter has been installed following a lagoon treatment process and is being used for the removal of algae prior to additional treatment in a subsequent nitrification process.

The FlexFilter has proven to be efficient for the removal of algae from lagoon effluent, which improves downstream treatment processes, and enhances the UV transmissivity for more effective disinfection. This installation will be the first FlexFilter system to be put into service since WWETCO, LLC was acquired by WesTech Engineering, Inc. of Salt Lake City, Utah, in December 2010.

WWETCO has developed products for combined sewer overflow and has engineered new and innovative ways to utilize compressed media filtration for both primary and tertiary treatment. The acquisition of WWETCO creates a partnership that will help to better advance these technologies.

With the recent launch of the WWETCO products under the WesTech umbrella and the exposure at WEFTEC, the new requests for information, design work and pilot requests has shot through the roof, explained John Gottschall, General Manager of WWETCO, LLC. The simplicity and flexibility of this product will truly be a game-changer in how we look at equipment for primary treatment, tertiary filtration, and CSO/SSO treatment.

Additionally, the WWETCO FlexFilter was recently featured in a conference paper given by Jim Fitzpatrick, P.E. of Black & Veatch Corporation at WEFTEC 2011 in Los Angeles. Jim Fitzpatrick is a Wastewater Treatment Process Specialist and is considered a leading expert in CSO and SSO treatment systems. Mr. Fitzpatrick’s paper focused on the successful piloting completed in Springfield, Ohio as well as the ongoing project design and implementation of the FlexFilter for Springfield’s upcoming CSO treatment system.

Some of the key points discussed included:

  • Passive control and the simplicity of system operation.
  • Physical barrier for removing particles vs. settling associated with other technologies.
  • Consistent achievement of effluent quality goals and effective pathogen reduction with conventional disinfection processes demonstrated by the pilot testing during actual wet-weather events.
  • Potential for its flexible operation as tertiary treatment that can be switched to CSO treatment during a storm event.
