Water Deionized - Typical Analysis

Synonyms include De-ionised Water, Deionized Water, De-ionized Water, Deionised Aqua, Deionized Aqua, Deionised H2O, Deionized H2O, Water Deionised, Water Deionized, Aqua Deionised, Aqua Deionized, Demineralized Water, Purified Water and Distilled Water.

At ReAgent, we can supply numerous grades of deionized water. To ensure quality, samples of our water are sent for third-party microbiology testing on a weekly basis, whilst regular chemical testing is carried out in-house prior to the water being demineralised. All of our water is supplied according to our ISO 9001:2000 accredited systems. The following description gives detail on our processes for manufacturing the various de-ionised water grades.

Mains water enters our building. The first phase of the water purification process is an Organic Trap, where a special resin removes most of the organic matter. Next, the water passes through a Twin-Bed Deionizer, where one Anionic tank removes the Cat Ions, the other Cationic Tank removes the An Ions. By now, the maximum level of impurities in the water is 10 µ per cm, already much lower than traditional Distilled water: it is typically much lower – around 1µ per cm. At this point, the water is can be called de-ionised.

To further reduce impurities, the water is then passed through a Mixed Bed Resin, where impurities are reduced to > 0.05 µ per cm. The deionized water is given Ultra Violet Treatment, during which phase the water is passed through a strong UV Light to kill any remaining micro-organisms. Finally, the water moves through a 0.2 micron filter. After the final stage, the water is "Ultra Pure Water".

At ReAgent, we do not use any untreated water for any of our products, or to put it another way, Deionized Water is the lowest quality water which we will use. We use Ultra Pure water for many of the solutions we manufacture, including pharmaceutical grade products. Please note, we do not recommend the use of treated water for human consumption; it is demineralized, all of the beneficial properties (minerals, ions etc.) have been removed, plus it has virtually no taste to it.

We can supply in pack sizes ranging from 1L to 1000L. To enquire about price and availability of our various grades of deionized water please contact us using the form below.
