Ion Exchange Resins

Widely used in different separation, water softening and water purification.

What is UV system?

A UV system is a technology that uses ultraviolet light to kill or inactivate microorganisms such as bacteria, viruses, and other microorganisms in water without introducing any harmful byproducts. It is commonly used for disinfecting drinking water and works by damaging the DNA of the microorganisms, rendering them harmless. UV systems are often used alongside other water treatment methods to ensure water safety. 

How does a UV disinfection system work?

The system consists of a chamber with UV lamps that emit UV light at a specific wavelength. When water passes through the chamber, the UV light penetrates the cells of microorganisms and damages their DNA. This prevents them from reproducing and makes them harmless. As a result, the water is effectively disinfected and made safe for consumption.

Mixed Bed Resin

Mixed-bed DI Ion Exchange Resins are normally used to ‘polish’ the water to higher levels of purity after it has been initially treated by either a two-bed deioniser or a reverse osmosis unit. In mixed bed deionisers the Strong Acid Cation and Strong Base Anion resins are closely mixed and contained in a single pressure vessel.

Our Mix Bed Deionising resins can produce the highest quality of deionised water possible, however, feeding untreated water into a mixed bed unit can be an expensive option and may not produce the water quality required.

In order to obtain the purest quality deionised water, a reverse osmosis system should be used before the water is treated through the Mixed Bed unit. While the reverse osmosis system removes most of the impurities the mixbed resin removes the rest of the ions in the water.

Deionised Water Filtration Systems

We stock a wide range of deionized water systems, DI resin vessels, DI resin filter cartridges and water deionisers.

Softening Resin

It is a strong cation ion exchange resin supplied in its sodium form, it is normally used to soften hard water. Water hardness is usually calculated as Ca2+ and Mg2+.

Water Softener Resin exchanges the hardness minerals (calcium and magnesium) dissolved in water for sodium. This soft mineral is contained on the softener resin beads and does not build up on surfaces as scale deposits.

The water softener resin is regenerated with a brine solution (salt).


Water Softeners

MDC Water offers a wide range of quality water softeners for residentional, commercial and industrial applications.

What is Ion Exchange Resin?

Polymers that are capable of exchanging ions with ions in a solution that is passed through them.

They are used to remove dissolved particles from liquids. Therefore, functional groups are bonded to the polymer beads. These functionalized polymers adsorb particular anions or cations from the liquid and discharge others.

While RO Membrane technology is very cost-efficient for water with a high salt content, only ion exchange resins can purify water with low salt concentrations to the point where only trace amounts remain.
