Device Description
Sartorius arium
®
mini systems were designed to produce ultrapure water.
The arium
®
mini plus is directly connected to the potable water supply and purifies
the water in two stages. In the first stage, the arium
®
mini plus produces Type 3 pure
water (reverse osmosis water), and in the second stage, ASTM Type 1 ultrapure water.
The arium
®
mini does not have a pre-stage. The device must be manually fed with
pretreated water and is not suitable for direct connection to the potable water
supply or a pretreated water line. In the second stage, the system is identical to an
arium
®
mini plus and produces ASTM Type 1 ultrapure water.
Because the ultrapure water production reaches higher flow rates than the pure
water production in the arium
®
mini, an arium
®
bag is connected as buffer storage
between the two stages. On the arium
®
mini, the bag is used for storing the manually
prepared, pretreated water. The water conducted into the bag can be taken directly
out of the bag. The extraction is carried out without pressure, e.g. using a ball cock.
Fig. 3-4 and Fig. 3-5, page 12 show the flowchart of the arium
®
mini plus and the
arium
®
mini. In the arium
®
mini plus, a membrane pump behind the system inlet
transfers the water through the pretreatment cartridge. The pretreatment cartridge
has two outputs, one for permeate and one for concentrate flow. The concentrate
flow is connected to the outlet (drain) of the system. While the first stage fills the
bag, water drains out at the outlet. The permeate flow contains the purified RO
water (pure water). A conductivity-measuring cell (LFP) monitors the quality of the
RO water.
On the arium
®
mini, the membrane pump is used at the system inlet to fill the bag.
In the second step, another pump pumps the pretreated water (pure water) from
the bag into the ultrapure water purification system. Here, the pure water is further
purified to ultrapure water by an optional UV lamp and a cartridge filled with
activated carbon and ion exchangers. A conductivity-measuring cell (LFP) measures
the conductivity of the ultrapure water. The last purification step after dispensing is
to run the water through a sterile final filter.
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 cartridge. If there is no more
interaction for a certain time, the device automatically switches to ECO mode.
In ECO mode, the arium
®
mini plus continues filling the bag. Once the bag is
completely filled, the system automatically switches to standby mode after
15 minutes.
3.2.2 Feed Water Tubing
The feed water tubing is used to supply tap water to the arium
®
mini plus.
