Process flow (to be read in conjunction with flow diagram)
All external hydraulic and electrical connections are positioned at the rear of the
unit, to protect them from accidental damage.
Potable feedwater enters the unit and is treated by the Pre-treatment pack,
(carbon), protecting the reverse osmosis membrane from possible chlorine
degradation. The treated water then enters the reverse osmosis module/s.
Purified water passes through the membrane and is termed; the permeate (85-
95% of salts removed). The water containing the rejected salts passes across the
membrane and out of the RO module to drain and is termed, the concentrate.
The concentrate flow rate is controlled by a fixed orifice restrictor located in the
drain line and is set at approximately 60 ltrs/hr.
The permeate leaving the RO module is pressurised by a recirculation pump
before being further purified by a Puripac media pack containing mixed ion-
exchange resin and activated carbon. The purified water if then filtered by a
0.1µm filter before passing to the dispense valve located in the pod of the HP.
Purified water is circulated around this loop on a continuous base through the
storage tank.
