Description of System Operation

The discs are color-coded by micron size and are stacked on a spine. The spine assembly has a spring compression unit and an internal piston which are used to alternately compress and release the discs during filtration and backflush cycles. During the filtration stage, water flows through the inlet manifold and is distributed through the backflush valves into the filters. The water then passes through the filter elements to the outlet manifold for consumer use.

FILTRATION MODE
During the filtration process, the filter discs are tightly compressed together by the spring and the differential pressure, forcing the water to flow through the grooves and traps of the discs.

BACKFLUSH MODE
During backflush, the discs are released by the inlet hydraulic pressure. Multi-jet nozzles provide peripheral spray on the loosened discs causing them to spin and release the retained solids, which are flushed out to the drain.

System Maintenance

WEEKLY MAINTENANCE CHECK:

Inlet/Outlet Pressure (40 psi upstream during backflush)
Backflush Controller (PD gauge returns to 0-2 psi
after backflush)
Leakage
Clean Command Filter

MONTHLY MAINTENANCE CHECK:

Solenoid
Downstream Pressure and Drain
Backflush Valves

SEASONAL MAINTENANCE:

Close the water inlet after backflushing the system.
Make certain there is no pressure in the system.
Remove the cover by opening the clamp.
Unscrew the butterfly nut on all the filtration elements and remove the tightening cylinders.
Remove each disc set and tie each set on a string.
Place the discs in a cleaning solution, 10% Chlorine solution for 30 minutes for algae and organic material and Muriatic acid for 30 minutes for iron bacteria.
Thoroughly rinse the discs with fresh water and reassemble the discs on the spines.
Check that the correct level of discs are assembled on each spine: compress the discs with two hands and make sure that the top disc reaches the imprinted circle on the outside of the spine.
Reassemble the tightening cylinders and tighten the butterfly nuts. Use the butterfly wrench to ensure that the nuts are sufficiently tightened.
Reassemble filter covers and tighten the clamps.
