Technological scheme of RObust 1000 is shown in Figure 2. After the pre-filters, the pressure
booster pump feeds the water to the reverse osmosis membrane array with two membrane
modules. Permeate from both modules goes to the permeate collector, and concentrate from the
1 and 2 modules goes to the 3
st nd
the concentrate is discarded to drain via concentrate flow restrictor and drain port in port rack.
Pressure gauge no. 2 shows pressure between the 2
purified water line or pressure tank (if installed), passing through the carbon post-filter. Purified
water line may go to purified water faucet or be connected with some other consumer appliance.
High-pressure switch installed before the post-filter 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 to feed water into the system. When purified water
stops being drawn from the system, pressure starts to build up and closes high-pressure switch
switching off the system.
