specified in the CONTECH Product Design Manual, operators may adjust the flow rate <br /> through the filter cartridges. By decreasing the flow rate through the filter cartridges, the <br /> influent contact time with the media is increased and the water velocity through the <br /> system is decreased, thus increasing both the level of treatment and the solids removal <br /> efficiencies of the filters, respectively(de Ridder, 2002). <br /> Recommended research and development: <br /> Ecology encourages CONTECH to pursue continuous improvements to the StormFilter. <br /> To that end, CONTECH recommends the following actions: <br /> • Determine, through laboratory testing, the relationship between accumulated solids <br /> and flow rate through the cartridge containing the ZPGTM media. Completed 11/05. <br /> • Determine the system's capabilities to meet Ecology's enhanced, phosphorus, and oil <br /> treatment goals. <br /> • Develop easy-to-implement methods of determining that a StormFilter facility <br /> requires maintenance (cleaning and filter replacement). <br /> Contact Information: <br /> Applicant Contact: Jeremiah Lehman <br /> Contech Engineered Solutions <br /> 11835 NE Glenn Widing Drive <br /> Portland, OR, 97220 <br /> 503-258-3136 <br /> j lehman(c�r�,conteches.com <br /> Applicant Web link http://www.conteches.com/ <br /> CONTECH-StormFilter®GULD Maintenance Update(November 2012) Page 111 <br />
