OPERATION
Filtration Process
The filtration process includes a Filtration Cycle and a Backwash Cycle.
During the Filtration Cycle, water enters the system inlet port and passes through the filter elements before exiting via the Permeate outlet.
This system is designed so that no valves are powered during the Filtration Cycle. This allows water to contin- ue to be filtered during a power outage and it minimizes electrical power consumption.
After a period of time, the filters have to be cleaned. This is accomplished through the Backwash Cycle.
During the Backwash Cycle, filtered water from one of the cartridges is fed back through the other cartridge to break up any debris collected on the membrane walls.
The Backwash Cycle includes a forward flush step which then uses the feed water to flush away the loos- ened debris from the cartridge’s membranes. The valves are only powered during the flushing cycle and in STOP MODE.
NOTE: Both the Filtration and Backwash cycles can be completely automated through the Control Panel. See the Programming section within this manual.
