Commercial Water Deionizer Systems

UAE Water Filters Systems has designed, installed and maintained custom water purification systems for commercial and industrial customers. We have an array of commercial water deionizers that can best balance low cost and efficiency for your applications. We study your use of water to determine whether a system needs custom engineering. Our engineers maintain a close relationship with manufacturers to implement the latest purification technology. The International Water Quality Association has certified our technicians as experts who provide support and service outstanding in their field.


Our Commercial Water Deionizer Systems

Portable Exchange Service Deionizer Tanks


Portable ion exchange service tanks provide a constant supply of extra-purified water in a safe and cost-efficient

method. For optimum water quality, we stock a variety of types in many sizes in order to use tanks appropriate to your needs. Eventually, each tank becomes spent and no longer effective in removing contaminants. When this happens, an expert UAE Water Filters technician will come to exchange the tank to keep the system running at full capacity. 

Automatic Two-Bed and Mixed-Bed Deionizers

For industrial water purification, UAE Water Filters Systems uses either dual-bed or mixed-bed filtration. Two-bed deionizers hold cationic resins in one vessel and anionic in another. Two-bed filtration is used when water is only being pretreated, or the water purity standard is not extremely high.
In a mixed-bed deionizer, both resins are in a single vessel. This brings water purity to the most stringent level. This type of systems is often found in medical applications.

Combination RO/DI Systems

Reverse osmosis and deionization are combined to remove minerals and odors. This brings water contamination to near-zero levels.


The deionization process captures mineral ions — including cations like sodium, calcium, iron, and copper, and anions such as chloride and sulfate — that RO filtration cannot remove.  This process removes nearly all minerals, and is often used as final stage treatment for pure and ultrapure waters.

There are several different deionization systems. Service deionization (SDI) uses synthetic resins to remove ions. Electrodeionization (EDI) systems offer continuous deionization, since they use DC current to continuously regenerates the synthetic resins. Deionization units can also be combined with RO units into a single system.



  • Required flow rates and final water quality requirements,
  • Sizing, and materials of construction, including piping



  • ‘Polishing’ water from RO units to increase water resistivity and lower conductivity



Do I need to exchange or regenerate a deionization system offsite?  SDI units require offsite deionization.  EDI units do not require regeneration or exchange, since the regenerate the resins inside the unit

Are there any uses for deionization besides RO polish? Yes, in some cases EDI continuous deionization can be used to reduce/reuse waste water produced by an RO system by up to 85%.

What things do I look for if my continuous deionization system isn’t running well? Review DC voltage and amperage, look at pressure drops and flow rates. Reading outside the normal range for either will give you valuable information about the source of the problem.


Does Your Business Need a Commercial Water Deionization System?

In order for us to gain an understanding of your business’ water supply, we provide a free water test that works to identify and isolate which chemicals are present in your business’ water. After we have a general idea of what is in your water, we can work to develop the correct commercial water treatment solution for your business’ needs. Contact us today and our experts will come and evaluate your business’s water quality!
