What is a demin plant?

A fast and efficient pure water solution

A demin plant performs water demineralisation, a form of water purification in which mineral content is removed from water. The process removes almost all the dissolved salt and mineral ions present within the water, leaving pure water behind. 

Our EX Power demineralisation plant provides large volumes of pure water with a short regeneration time of around 20 minutes.

The benefits of demin water

Higher quality, higher flow rate and faster regeneration

Demineralised water is used where a high level of water purity is required. Demin water is typically used for:

Manufacturing processes where tap water could react with other ingredients.

As part of food and beverage production.

The pharmaceutical and cosmetics industries.

In industrial processes for product cleaning and rinsing.

In water cooling and car batteries.

A demin water plant is generally easy to maintain and is a great way to provide manufacturers with the pure water they need.

We have worked with Excel Water for many years and trust their prompt, reliable service.

How does a demin plant work?

Demin plants (also known as DM plants) consist of two pressure vessels: one containing cation and the other containing anion exchange resins.

Raw water passes through the cation vessel first, where positively charged ions are chemically exchanged for hydrogen ions. Water then continues to the anion vessel where negatively charged ions are chemically exchanged for hydroxide ions. The hydrogen and hydroxide ions combine to create pure water.

A demin plant needs to be regenerated with hydrochloric acid and sodium hydroxide when necessary. So, the site where the plant is installed need to adhere to the COSHH Regulations.

A typical demin plant takes between 2 – 3 hours to regenerate. The regeneration of our demin plants takes approximately 20 minutes, meaning there’s very little downtime.

Our demineralisation plant, the EX Power, easily provides large volumes of pure water of less than 2 micro siemens, without the need for pre-treatment or post-treatment like Reverse Osmosis Plants. Since they are a stand-alone unit, they do not require a large amount of floor space either.

The drain should be capable of the maximum flow, as specified in the technical manual and withstanding 15% alkaline and acidic solutions. Waste must be checked and the local water authority consulted before disposal. The customer is responsible for ensuring the effluent is within their consent to discharge levels.
