Function
Reverse osmosis is a membrane separation process whereby water is pumped at high pressure onto a semi permeable membrane. The dissolved salts (concentrate) are rejected by the membrane and water molecules flow through the membrane as purified water (permeate).
Over 99% of dissolved salts are removed including the rejection of micro organisms such as bacteria and pyrogenics.
The treated water (the permeate) is stored in the reservoir tank of the plant and from here it is pumped to point of use. The concentrate is piped to drain.
Pressure
The plant is built with integral reservoir and pump, the pump pressure being 2m cubed /hour at 3.7 bar pressure - 50 psi. The pump is pressure controlled by a pressure switch.
The plant is equipped with a by-pass function which means that is the plant is not operating raw water can still be fed to points of use if required.
Quality
Water purity is dependant on feed water quality. Typically on mains water the unit will produce a water quality of approximately 20us/cm or better. A conductivity meter can be added as optional equipment.
