3.2 Process Description
The PURELAB Option-S US process links three purification
technologies, reverse osmosis, adsorption and de-ionization and also
incorporates an optional RO feed water boost pump.
The unit is designed to operate from a good quality potable water
supply, and produces either 7 or 15 liters per hour of purified reverse
osmosis grade water which is collected in a treated water reservoir.
A graphics screen displays the system status and provides control by
means of three function buttons.
The water is processed and treated by the PURELAB Option-S US
unit as follows:
•
Potable water enters through a strainer and inlet solenoid
valve at either regulated mains water pressure, or is pumped
by means of a feed water pump (optional), and passes
through the pre-treatment cartridge. The pre-treatment
cartridge has been designed to protect the reverse osmosis
cartridges from particulate/colloidal matter and excessive
free chlorine, which may be present in the incoming
feedwater.
•
The permeate water then passes through one or two reverse
osmosis cartridges, set up in series, which split the flow into
permeate and concentrate streams. The permeate water is
further purified whilst the waste concentrate stream is
passed to drain.
•
The permeate water then passes through the ion-exchange
cartridge which removes dissolved ionic impurities from the
permeate water.
•
Finally, the water is passed through a:
•
Water quality sensor, which measures the resistivity of
the water.
•
Temperature sensor which provides accurate
temperature measurement.
