WAPO TEC Sand and Multimedia Filters
Heavy-duty deep-bed sand and multimedia filters, 2 to 10 ft diameter, with air scour and Hyflow diffuser
Overview
WAPOTECH's US site describes a range of heavy-duty deep-bed WAPO TEC filters from 2 to 10 ft in diameter for various applications with many options. The patented WAPO TEC Hyflow Diffuser, described as a standard feature in most of its NSF 50 certified sand and multi-media filters, is intended to keep the filter surface even. The filters are nozzle-plate designs that can be air scoured in combination with a separately applied water backwash, which the manufacturer says saves water and energy while improving backwash effectiveness.
The Austrian site adds detail: WAPOTEC specializes in DIN-conform filters delivered to various specifications, offers four series, and the filter types E, S and N come with the Hyflow fluid introduction device, sight glasses, spotlights, air-release and venting valves. Options include adapted filter beds, ozone-resistant models, divided or shortened base frames, flanged filters and on-site lamination. Interior diameters between 800 and 3,000 mm and different heights are published. WAPOTEC also offers multiSorp filter materials.
WAPOTECH pairs the filters with filter cleaning and remediation services (a 3-step process after Legionella or Cryptosporidium contamination, performed in 8 to 16 hours per the manufacturer) and DesoClean engineering services for cleaning and disinfecting filter media, equipment and pipework.
