Modes of Operation
Filtration:
During normal filtration, water is pumped to the filter via the internal riser pipe assembly and evenly
distributed over the media. As the water travels down through the media bed into the under-drain,
suspended particles are trapped. When the filter media requires cleaning, Miller-Leaman’s
MAXIM
Controller will trigger a backflush cycle and automatically clean the filter. This may be triggered by
the differential pressure sensor, the backflush timer, or manually by the user.
Backflush:
Once a backflush is initiated, the pump will turn off while the valves rotate to the backflush position.
When the valves are in the backflush position the pump is turned on. The reverse water flow lifts
and churns the media bed creating a scouring action to release the captured debris. This debris is
then flushed out of the backflush manifold. The filter is configured to be backflushed with source
water from a Tower Water Supply.
After the backflush cycle is completed, the pump turns off while
the valves rotate back to the filtration position. When the valves are in the filtration position the
pump turns back on and normal filtration resumes.
