Arium® Bagtank Water Storage
Reliable Intermediate Water Storage That Protects Your Water Quality
The innovative Arium® Bagtank uses a closed system to store your purified water and protect it from secondary contamination and keep the quality. Instead of a regular tank, the Arium® Bagtank utilizes exchangeable bags to simplify maintenance and remove the need for time intensive cleaning procedures. Simply exchange the bag in 5 minutes, fill it up and you are ready to go.
- Integrated ventilation filter with non-return valve provides reliable protection against CO₂ pollution
- High flexibility through the 4 rollers available as an option (50 & 100 L Bagtank)
- Easy and fast exchange of the Arium® Bags
- No chemical cleaning required
Choose the Right Bagtank for You
Depending on your daily pure water consumption, the Arium® Bagtank is available in three different volumes: 20, 50 and 100L. If higher water preasure and/or flowrate are required you can equip the Arium® Bagtank with an internal (50 and 100L) or an addition external (20L) pump.

Compatible Water Purification Systems
The Arium® Advance EDI and Arium® Advance RO systems achieve high retention rates of ions with an optimal water yield to remove impurities from your feed water.
The built-in iJust function also optimizes purified water quality and water usage. Pure water is stored and ready to be used in the innovative, closed Arium® Bagtank system, which protects water from secondary contamination.
The Arium® Comfort is a combined water purification system and produces either ultrapure and pure water (Comfort II) or ultrapure and RO water (Comfort I). Directly connected to a potable feed water source it uses RO technology, combined with EDI technology (Comfort II), to produce pure water. The purified water is then stored in the Arium® Bagtank system before used as feed water for the polishing cycle to produce ultrapure water.
The Arium® Pro series meet and exceed the ASTM Type 1 water quality standards and ensure reliable reproducible results. When a pretreated feed water source is missing, connect the Arium® Pro to an Arium® Bagtank for a reliable feed water source. The Bagtank should in turn be connected to a pretreatment system such as the Arium® Advance.

Frequently Asked Questions
The Arium® Bagtank is compatible - and should be used as an intermediate storage unit in combination with - the following Arium® water purification systems: Arium® Advance RO and EDI, Arium® Comfort I and II.
The difference between the Arium® Bagtanks is storage volume. So Arium® Bagtank choice depends on factors like total daily consumption and maximum peak consumption. The production output of the water purification system connected to the Arium® Bagtank should also be considered, as that will impact which Arium® Bagtank will cover your lab water consumption.
The biggest benefit is the cleaning process when compared to a standard storage tank. Cleaning a standard tank requires chemicals and a lot of time. The chemicals add the risk of contaminating the water and introducing chemicals into the system. With the Arium® Bagtank, you can forget all about that. Arium® Bagtank-bags are disposable, so instead of cleaning you only need to change the bag. The process takes roughly 5 minutes as opposed to several hours.
Yes, you can connect 1 Arium® Smart Station Pure to dispense RO/pure water (depending on water purification system) directly from the Arium® Bagtank.
