Standard Specifications
Filter screen cartridges shall be a single-piece unit of all-welded 304 stainless wedge wire construction with 125 PSI collapse strength and 400 PSI burst strength. Filter housings shall be constructed of all-welded and ribbed 304 stainless steel and rated 125 PSI operating pressure. Each filter housing is to be equipped with an individual 3-port, two-way backwash valve, which is constructed of ductile iron and is hydraulically operated. Wetted surfaces of the backwash valve shall be coated with 3M-134 industrial-grade epoxy.
Backwashing is to be accomplished by a full reverse flow of water through the screen cartridge. Normal backwash cycle time shall be 15 seconds per filter. A minimum of 25 PSI is required for inlet and discharge lines. Filters are to be manifolded together with carbon steel manifolds, whose interior surfaces have been sandblasted and epoxy-coated. Manifolds shall have grooved connections for Victaulic-style couplings.
Automatic backwash shall be initiated by pressure differential or timed interval through a solid-state controller with status lights and LCD backwash record display. Controls shall be housed in a weather-resistant enclosure. The controller shall operate from a 120 VAC or 12 VDC power source. The complete STAK-Series system shall be factory assembled, tested, and skid-mounted with an appropriate lifting eye.
It shall include filter units, inlet, outlet, and backwash manifolds, a continuous acting air/vacuum relief valve, pressure gauges, automated backwash valves with associated hardware, and backwash control. The system shall be wired and ready for hook-up to power and supply lines.
