Fiberglass reinforced plastic tank is the cylinder shaped plastic vessel with the filter
media. Control valve is mounted on the threaded top opening. Riser pipe runs down to
the bottom of the tank inside the pressure vessel, transporting water out of the filter during
service and into the filter during backwash. Bottom distributor is attached to its end to spread
flow of water uniformly and screen against fine particles.
Brine regenerable systems (FU and FK) include a brine tank – a plastic container with salt
pellets where the brine is stored then drawn from during regeneration.
Control valve.
CE, CI, and CT type control valves use a plunger piston mechanism to route influent water
accordingly to the current cycle of operation. DV valves use a rotary disk mechanism.
CE, CI and DV control valves for softening systems (FU and FK series) have 5 cycles;
non-brine regenerable filters have 3 cycle CT control valves. The cycles are as follows:
1.
in service mode, inlet water is sent through the filter bed to the purified water outlet;
2. during backwash, the control valve sends inlet water across the filter bed in the upflow
direction to fluff it up and release trapped impurities to drain outlet;
3. during fast rinse, inlet water is sent through filter bed downflow and then to drain outlet;
4. (CE, CI, and DV only) during brine regeneration, inlet water is sent through brine injection
system to suction brine from brine tank and slowly displace it across filter bed to drain outlet;
5.
(CE, CI, and DV only ) during brine tank refill, inlet water is sent through the filter bed,
softened effluent refills the brine tank.
