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.
