Arium® Bagtank - Protecting Your Pre-Treated Water
Storage of pre-treated water, whether
for direct use with water consuming
systems or for further processing into
Type 1 ultrapure water, is often anunderestimated step. It plays a vital rolein maintaining the high quality of the
pre-treated water by protecting it from
impurities found in the direct orindirect ambient environment.

2--Key Features of the Bagtank:
Unique tank design, enabling reliable
storage of Type 2 and Type 3 purewater
Uses disposable Bag technology thatis proven by the bio-pharmaceuticalindustry
Easy to maintain - the Bag can beexchanged within five minutes
Compatible with Arium® Smart
Station Pure for Pure water
dispensing directly from the Bagtank
Offered in three different volumes:
20, 50 and 100 L

Arium® Bagtank - Reliable and Safe Intermediate
Water Storage
An intermediate water storage isneeded with water purification systems
that use filter-based purification
methods for producing pre-treatedwater. Filter-based purification
methods, such as depth filters, RO
membranes and EDI modules, slow
down the production rate to such a
degree that it would not be able todirectly dispense water at a sufficient
rate or pressure. The intermediatewater storage system overcomes thisproblem by gathering and storing the
pre-treated water in larger volumes
until it is needed.

Feed laboratory devices e.g. glass
washers, ice machines, autoclaves,etc.
Dispense pure water directly from the
Bagtank for rinsing, general, andother non-critical applications		3

Cleverly Combined Technology for
Optimal Storage of Pure Water
When storing water, not only is thematerial that is in direct contact withthe water decisive, but also the housing
in which the water container isintegrated.
It is crucial to take both aspects into
account to achieve optimal water
storage conditions and the highest
user benefit.

4With the Arium® Bagtank the housing
has been designed for efficient space
use and ability to deliver pure waterwhere needed. The water itself is storedin our innovative Arium® Bag. With its
high-quality material, the Bag
minimizes the amount of downtime
because of cleaning.

S71 - The Chosen Material for the Arium® Bag
The S71 EVA film of Arium® Bags is the result of combining material science andfilm extrusion expertise in collaboration with our film partners. Such partnerships
ensure a full understanding of the film manufacturing process.

---Key Features:
Heat laminated EVA/EVOH/EVAstructure
Up to 360 μm total layer thickness
High robustness based on the film
strength and film flexibility
High gas and water barrier properties
for optimized temporary waterstorage
Low extractable profiles

Save Time and Water During Cleaning
In contrast to typical PE water storage
tanks, the Arium® Bagtank uses
exchangeable Bags, reducing themaintenance downtime to a minimum(see Figure 1).
Instead of using chemicals, which
require a long exposure time in thetank, followed by multiple time1

intensive rinsing cycles, the empty
Arium® Bag is simply replaced within
five minutes.
Finally, by exchanging the Bags, youensure that the accumulation ofimpurities over time (typically seen inthe critical upper part of PE tanks) isavoided.

8Choosing the Right Bagtank Size
When choosing a water storage tank,you will need to consider which size
would be the right choice. An undersized tank might not provide enoughwater to meet your consumption
needs, whereas an oversized tank may
impact the stored water quality overtime.

Furthermore, the production flow rateof your pre-treatment system will also
have an impact on the choice.
The Bagtank, together with the production flow rate of the pre-treatment
system, needs to cover both yourmaximum peak of water usage as wellas the total daily water consumption
needs.		910Flexible Water
Dispensing withArium® Smart Station
For manual or volume-controlled
pure water dispensing directly fromthe Arium® Bagtank, connect anArium® Smart Station Pure.
The Smart Station is designed forflexible remote dispensing of purewater directly at the point of use.
While dispensing water into a broad
range of different-sized containers,
the Smart Station offers constantcontrol of all important quality
parameters. The ergonomic design
supports left-and right-handoperation and can be easilyadjusted to your needs.
Using the extended connection
tubing, the distance between theSmart Station and the Arium®
Bagtank can be set up to four
meters. Based on your needs,
different filters can be added.
