Industrial Deionization
for High-Purity Water

We offer a range of mobile water deionization systems, also known as demineralization systems, that utilize ion exchange resins to effectively remove dissolved solids from water. Deionized water is essential in various industrial processes, including manufacturing, production, and water pretreatment. It also plays a key role in optimizing boiler and cooling tower feed, leading to reduced chemical usage and improved efficiency.

Our water deionization systems are available in various configurations to suit your specific needs:

Trailer-Mounted: Conveniently transport these systems to any location for a rapid and efficient temporary supply of high-purity water.

Skid-Mounted Pressure Vessels: These free-standing units offer flexibility for on-site installation and operation.

Exchangeable Media VesselsBenefit from deionized water with convenient and sustainable exchangeable media vessels.

Furthermore, we operate ion exchange resin regeneration facilities across Europe. This service minimizes chemical handling on your site and provides an environmentally friendly solution through the recycling of spent ion exchange resins.

Typical Applications

Ensuring a continuous supply of treated water for all emergency scenarios, such as resin bed contamination and plant failure.

Offering full replacements or partial components for various processes you might need during this interim period, catering to a wide range of applications, including resin replacement.

Providing additional volumes of make-up water required in excess of the capability of the installed plant during plant start-up. 

Supplying additional volumes of demineralized water over and above the capacity of the permanent plant due to the requirement to vent high volumes of steam to the atmosphere. 

Supporting the existing plant to ensure site production is maintained during shortages of supplies such as acid and caustic for demineralization plants.

Success Story

Our client, a nuclear decommissioning company contracted by the Nuclear Decommissioning Authority, faced the challenge of decommissioning a UK power station that had ceased operations and was being defueled. This facility previously consumed 910 m³/day of demineralized water, which had decreased to 26 m³/day after power generation ceased. The on-site demineralization plant was oversized and costly to maintain. 

Our solution involved providing a MODI 15000T trailer-mounted mobile demineralization plant, offering ion exchange demineralization at a reduced flow rate. Once the ion exchange resins were depleted, the MODI 15000T trailer was returned to MWS’ central media regeneration station, eliminating the need for chemicals and effluent disposal. This approach reduced costs by 50% compared to operating the on-site plant and allowed for the early removal of the redundant demineralization plant, enhancing operational efficiency.

Water Deionization FAQs

Deionization is a water treatment process that removes mineral salt contaminants from water. Specifically, the purification process removes cations, such as calcium, copper, iron, sodium ions, and anions such as bromide and chloride. Deionization systems utilizes ion exchange resins to effectively remove dissolved solids from water and purify potentially contaminated water. The resins bind with any mineral salts in the liquid to separate them from water, so that only clean water leaves the tank. 

Mobile water deionization systems use ion exchange resins to remove dissolved solids from water. Chambers are filled with ion resin and separated by ion-exchange membranes. Water flows through a bed of resin beads that have positive or negative charges. Positively charged resin attracts and traps negative anions, while negatively charged resin attracts and traps positive cations. The resin then releases hydrogen ions in exchange for the cations and hydroxide ions in exchange for the anions. The hydrogen and hydroxide ions then combine to form water. All that remains is water molecules, which is why deionized water has a reputation for being one of the purest forms of water.

Distilled water is not the same as deionized water. Distilled water is water that has been heated to its boiling point, causing any impurities to evaporate. The resulting vapor is then condensed back into a liquid, leaving behind any contaminants. This process of distillation can be used to produce drinking water, as well as water for other purposes.

Water that has been distilled is completely free of contaminants and minerals, making it ideal for use in pharmaceuticals or by people with sensitive skin or allergies. Because of its purity, distilled water can be stored for an extended period of time, ensuring safe water for use.

Deionized (DI) water is distilled water from which all contaminants have been removed. This results in the removal of dissolved minerals and salts. Deionized water is not the same as distilled water, which has had all its impurities removed through a distillation process. 

Most commercial and manufacturing industries use deionized water to avoid the potential of sediment buildup that could affect the longevity of their equipment. And because DI water does not conduct electricity, it can be used safely in electrical applications.
