A mixed bed deionizer puts cation and anion resin together in a single vessel, so the water passes through thousands of tiny exchange stages in one go. Anything dissolved in it, such as calcium, sodium, chloride and silica, gets pulled out, and what comes through is very pure water. Plants usually install it as a final polishing step after RO. At Water Treatment LLC we supply complete mixed bed deionization system units and mixed bed resin for factories, labs, power plants and hospitals across the UAE.
Features
- Cation and anion resin in one vessel for a very high purity output
- Treated water conductivity can drop below 0.1 µS/cm
- Works well as a polisher after RO or a two-bed DI system
- Vessels in FRP, stainless steel or rubber-lined steel to suit your site
- Fitted with inlet and outlet valves, sampling point and pressure gauges
- Resin can be regenerated in place or exchanged as a service tank
- Compact skid-mounted design that fits small plant rooms
- Fits easily into existing pretreatment and RO lines
Applications
- Pharmaceutical and laboratory water
- Boiler feed and power plant makeup water
- Electronics, semiconductor and battery manufacturing
- Chemical, paint and cosmetic production
- Automotive, glass and metal finishing rinse water
- Resin for industrial water treatment in UAE projects needing very low conductivity

Frequently Asked Questions
What is a mixed bed deionizer, and where can I buy one in the UAE?
A mixed bed deionizer combines cation and anion resin in a single vessel, so water passes through thousands of tiny exchange stages in one go and comes out as very pure water. It is usually installed as a final polishing step after RO. Water Treatment LLC supplies complete mixed bed deionization systems and mixed bed resin across the UAE. Contact us to discuss your project.
Which mixed bed deionizer size and vessel material is right for my plant?
Our systems are built to order from 0.5 m³/hr to 50 m³/hr and above, with vessels in FRP, SS304/316, or rubber-lined mild steel. The right design depends on your feed water analysis and daily demand. Share your flow rate and water analysis with our team and we will confirm the final design.
Can a mixed bed deionizer be used as a polisher after RO?
Yes. It works well after RO or a two-bed DI system, and treated water conductivity can drop below 0.1 µS/cm, with resistivity up to 18 MΩ•cm. RO permeate or softened water with conductivity below 20 µS/cm is recommended as feed. It is used for pharmaceutical and laboratory water, boiler feed and power plant makeup, and electronics manufacturing. Tell us your application and we will confirm the right setup.
What is the price of a mixed bed deionizer in the UAE?
The price depends on flow capacity, vessel material, resin quantity, and the regeneration setup. Send us your flow rate and water analysis on WhatsApp or email, and we will reply with a quotation.
Do you supply replacement mixed bed resin, installation, and regeneration support in the UAE?
Yes. Water Treatment LLC keeps fresh resin in stock for replacement or top-up, and our team handles installation, startup, and regeneration training, with support after the sale. We deliver across the UAE and GCC. Send us your requirement and get a custom quote.
