De-Ionisers |
| |
OVERVIEW |
| |
 |
Deionization is the only commonly available way to achieve a resistivity of 18.3 Megohm. This resistivity reading guarantees water free of ionic contaminates but does not address Organics, Bacteria, Microbials or even some Particulates. To remove these contaminates other types of purification are needed such as Carbon Absorption and Filtration.
Resistivity is the measurement of how little electric current will pass between two electrodes at a specific temperature.

HOW DOES A D.I. WORK |
| |
Water flows through a Cation resin where all cations are removed and replaced with hydrogen ions.
This water then flows through an Anion resin where all anions are removed and replaced with hydroxil ions. In most cases this is carried out by the use of a two tank system, in some circumstances a third polishing tank is used to give > 16 Megohm. Where 18 Megohm is required the water is passed through a high grade Mixed bed resin. |

SIZING |
| |
The size of a D.I. will depend on the amount of resin required for the application needed, this is a factor of the following:
- Max. flow rate required per hour.
- Quantity of water required between regenerations.
- Quality of incoming water.
Clarwick can advise on the best system to suit your needs. |
