EPD hi-rate permanent media filtration systems (poly-lined steel and FRP)
Horizontal multi-tank sand filtration for large pools and water parks
Overview
EPD USA builds horizontal hi-rate permanent media filter systems in two tank families: carbon steel lined with rotationally molded Primabond polyethylene, and fiberglass-reinforced plastic with epoxy vinylester resin. Systems are supplied as one- to multi-tank batteries with cast bronze backwash valves and manual, semi-automatic, or PLC-based automatic backwash controls. They suit municipal aquatic centers, water parks, and large natatoriums that need drinking-water-grade clarity in a low-height mechanical room.
