CDS Technologies' Media Filtration System Earns Approval From Washington State Department Of Ecology
System can now be specified and installed in all jurisdictions following WA DOE guidelines for emerging storm water treatment technologies
Morgan Hill, CA -- CDS Technologies, the industry's leading provider of comprehensive storm water, CSO and wastewater treatment equipment, today announced its Media Filtration System has received approval under the Conditional Use Designation as a Best Management Practice (BMP) from Washington State Department of Ecology (WSDOE).
The CDS Media Filtration System has undergone extensive testing according to the Wastington State's Technology Assessment Protocol – Ecology (TAPE) and can now be specified for installation by engineers, municipalities and contractors to meet storm water regulations for new developments and retrofit projects.
"We're pleased to provide customers a choice for storm water treatment equipment with higher pollutant removal capabilities," said Diane Warner, P.E., CDS Technologies NW Regional Sales Manager. "Our Media Filtration System provides more filtration per plan view square foot area. When compared to existing cartridge systems, we've nearly doubled the number of cartridges in a given system."
Interested parties can find more information on WSDOE's emerging technologies web site at http://www.ecy.wa.gov/programs/wq/stormwater/newtech/media_filtration.html. This initial conditional approval for basic treatment is the first step to achieving a general use designation. It uses media-filled cartridges to target project-specific pollutants such as heavy metals, oils, greases and a finer gradation of suspended solids.
The Media Filtration System is composed of rechargeable media-filled cartridges configured inside either precast or cast-in-place concrete vaults. In terms of sizing, CDS can configure the system inside manholes and vaults to treat flow rates ranging from less than a cubic foot per second (cfs) for small developments to vault systems treating in excess of 20 cfs for larger developments. The Media Filtration System is scalable and can be used in combination with standard CDS units upfront for primary clarification.
"We're currently testing our system with additional media options to earn an enhanced designation for removing phosphorus, nitrogen and heavy metals," Warner explained.
One unique design feature of the CDS Media Filtration System is its ability to hold a large portion of pollutants below the cartridges, which allows a higher quality of water to reach the cartridges for filtration. By using a series of media filtration cartridges and a sediment bay 18 inches below the level of the cartridges, the CDS Media Filtration System is designed for optimum settling of larger particles with adequate space to avoid impeding cartridge performance.
