Disc filter unit Forty-X®

strainerpanelfor water

Overview
The Forty-X® Disc Filter Armor series is a high-rate filtration device that utilizes an integrated pre-screen and stainless-steel panel designed to accommodate high solids loading capacities and greater hydraulic throughput. The woven optimum tertiary mesh (OTM) filter panel utilizes 316L stainless-steel threads to create a weave that improves solids collection and rejection. The panel configuration includes a robust, molded structural frame and a pressure assisted seal allowing panels to sustain and operate at a higher headloss and provide higher throughput compared to other woven polyester, flat panel disc filter designs. Evoqua’s Forty-X Disc Filter Armor series combines the technology of outside-in and inside-out filtration into a single PLC controlled unit; influent water flows through the prescreen (outside-in) into the disc filter panels (inside-out). This combination of two filtration technologies into one unit provides an effective and robust option for difficult applications.
