Classic UVF
Pre-treated water enters via an inlet solenoid and is then
pumped through the UV chamber, a purification pack, an
ultrafilter and temperature and water quality sensors before
being dispensed or re-circulated through a non-return valve
back to the pump inlet.
Purified water flows directly through the UV chamber where it
is exposed to intense UV radiation at a wavelength of 185 nm
to provide continuous bacterial control and the photo-
oxidation of residual organic impurities.
Ionic and organic impurities are removed by the purification
pack; the ultrafilter removes pyrogens, bacteria and other
microbial impurities as well as particles. Product water
resistivity and temperature are measured before dispense
and will indicate when the purification pack needs to be
replaced.
The water within the unit is re-circulated through the
purification technologies to maintain purity. To reduce heat
build up the recirculation is at reduced flow rate and is set to
be intermittent (5 minutes every hour).
An optional POU filter is available if required to protect the
outlet from bacterial contamination.
