1.6 Function of the RO unit

A semi-permeable RO membrane separates feed water of a
high pressure (approx. 8 bar) into deionised (permeate) and
into waste water (concentrate) with a high salinity.
The relation between the produced permeate and feed water is
expressed as recovery or WCF (%). The RO is factory set with
an WCF value of approx. 40%. With an appropriate water
pre-treatment, the operator may install the optionally available
"high efficiency" WCF kit.
