Water Deionisers

ADEPT Pure Water Limited offer a Full Range of Water Deioniser based Systems, these include the following units:

"I-on-x" Exchange Cylinders these are Single Vessels which hold "Mixed Bed" Resins premixed and require NO Regeneration Chemicals. These are exchanged when they are Exhausted. This is a simple solution used to process small volumes of water straight from a Potable Supply or Polishing Water from a Reverse Osmosis/Deionisation process. These units can last from 500 Ltrs to many thousands of litres it will depend on the Feed Water Quality coming into the Cylinder. They require the minimum amount of Staff Training and combined with a Wall Mounted Quality Meter which monitors the Water Quality, can offer a simple Automatic System which achieves surprisingly high water quality standards at a low price.

The Semi Automatic "Budget Di-on-x" and the Fully Automatic "Di-on-x" Water Deionisers, both of these systems have two Vessels linked together in series, the water flows through the First Vessel which contains "Cation" Resin which needs to be Regenerated with Hydrochloric Acid (Other Regenerates can be used, details on request) and then through the Second Vessel which contains the "Anion" Resin. This is Regenerated using Sodium Chloride (Caustic), this process is either Semi Automatic (requires a Regeneration Button to be pressed) and Automatic (Regenerates on a Set Point in a Quality Meter or a Production Capacity), If you have Chemicals on site and have experience with handling these chemicals and effluents then Deionisation is one of the best and more cost effect solutions to your Water Purification requirements compared with the water losses associated with Water Softeners and Reverse Osmosis.

Three Bed Deionisers these are called "Tri-on-x" and are a modified version of the Twin Vessel Fully Automatic "Di-on-x" Water Deioniser, this incorporates a third Vessel on the outlet of the Anion Vessel, and this Vessel contains "Cation" resin. This Resin's job is to polish the water and the most important design change to the system is that the Regeneration Chemical would normally flow through the Polisher Vessel then through to the first "Cation" Vessel, this ensures a high Regeneration state of the Polishing Vessel Resin. This System is mainly used to produce guaranteed water qualities higher than 1 Mega Ohm.

Regeneratable Mixed Bed Deionisers, these are a Single Vessel based System which has the two "Cation & Anion" Resins mixed together similar to the Mixed bed "I-on-x" Exchange Cylinders. This Unit will automatically mix and separate the Resins and then regenerate them using the Hydrochloric Acid & Sodium Chloride. These units are normally installed in Ring Mains to Polish the Water to Very High Standards normally > 15 mega Ohms they require Trained staff to maintain them.

Electro Deionisation (CDI or EDI), this is the process where the Ion Exchange Resin which is placed into a chamber and a DC Voltage is allowed to flow through the system. The voltage is maintained continuously while the system is running to Service, so NO Regeneration Shut Downs and No Chemicals are required, as the DC Voltage Regenerates the Resin. This process ensures very good Water Quality results of > 15 Mega Ohms. This System will require careful Monitoring and a good Maintenance plan, as Good Water Pretreatment such a Filtration, Water Softening and Reverse Osmosis will be required to operate it. They have many advantages over Standard Systems but they do require Fully Trained Engineers to Monitor & maintain them. They are normally used to produce Ultra Pure Water >15 M Ohm used in Pharmaceutical and Electronics manufacturing.
