Device Description
Ultrapure water stage (second treatment stage)
In the second treatment stage, the pretreated water is purified to ultrapure water
(ASTM type 1): The pretreated water stored in the bag (arium
®
mini plus and arium
®
mini) or directly fed pretreated water (arium
®
mini essential) is fed into the ultrapure
water circuit.
The water fed in can be freed from organic residues using an optional UV lamp
(185/254 nm). The pretreated water is then treated using the ultrapure water
cartridge (Scientific Pack).
The quality of the ultrapure water is monitored via a conductivity measuring cell (LFP).
3.5.4 Final Purification Stage
The ultrapure water passes through a final filter as it is dispensed. A sterile filter
or an ultrafilter can be used as a final filter.
3.5.5 Circulation of the Ultrapure Water
To guarantee ultrapure water of consistent and high quality, the ultrapure water
purification system is constructed like a circulation ring:
− If no water is dispensed, the water circulates through the UV lamp and
the ultrapure water cartridge.
− If there is no interaction with the device, the device automatically switches
to ECO mode.
