Wastewater mill DISCAM

impactverticalhigh-performance

With the ability to capture up to 95% of solids at 5- or 9-mm aperture sizes, this innovative solution combines a self-cleaning screen with a high-torque grinder. No manual attendance or cleaning is required, and disposal costs for handling debris extracted by traditional screening processes are eliminated. The Discam is constructed using a series of shafts, two of which are fitted with interleaving cutters and spacers to give positive displacement solids grinding; the remaining shafts are fitted with overlapping and intermeshing discs. Easily retrofitted into existing sewage pump stations or inlet works as well as installed in new-build facilities, this high-performance package is suitable for almost any type of wastewater facility. Features/Benefits Power savings, elimination of manual handling and associated transport costs, odor control, and automated operation are all achieved when installing a Discam to replace conventional screening systems to existing or proposed submersible pump stations Intermeshing discs give a self-cleaning screen Able to remove up to 95% of solids at the given aperture sizes Grinder allows liquid to pass through the cutter stacks, thereby filtering, trapping, and macerating the entrained solids Lower cutter tip speeds dramatically reduce impact load Slow speeds ensure low noise and vibration as well as good abrasion resistance Screening apertures at 5 and 9 mm available 1000-, 1500-, and 2000-mm channel depth options
