The pressure booster pump feeds the water to the first stage of the reverse
osmosis membrane array with two parallel 100 GPD membrane modules. Permeate
from both module goes to the permeate collector, and concentrate goes to the second
stage with one 100 GPD membrane module. Second stage permeate goes to the
permeate collector, and concentrate is discarded to drain via concentrate flow
restrictor and drain port in port rack. Pressure gauge no. 2 shows pressure between
the two stage of membrane array. Permeate goes to purified water line or pressure
tank if installed, passing through the carbon postfilter. Purified water line may go to
purified water faucet or be connected with some other consumer appliance.
High pressure switch installed before the postfilter reads pressure in permeate line
and starts the reverse osmosis system when it drops (due to taking of some water
from the pressure tank or opening purified water faucet). When the system switches
on, entry solenoid valve is opened and booster pump is powered up, which allows feed
water into the system. The water goes through 1st and 2nd prefilters, then is pressure-
fed by the booster pump to membrane array, where permeate is produced and sent to
permeate line to make up for the lost pressure in tank/pipe. When purified water
stops being drawn from the system, pressure starts to build up and closes high
pressure switch switching off the system.
Robust RO system has low feed water pressure protection implemented with a low
pressure switch, which prevents the pump and solenoid from operating if feed
