What is demineralised water (fully desalinated water)?

Jan 31, 2024, 14:51:35

VE water, also called demineralized water, demineralized water or deionized water, is treated water in which the conventional minerals (salts) have been removed. VE water is specifically required for technical applications, for example as a heat transfer medium in the cooling circuit. Sometimes demineralized water is also used as a cleaning agent.

In special cases even ultrapure water is required. Ultrapure water must meet certain purity requirements.

The quality and purity of demineralised water is determined by its electrical conductivity. The conductivity is usually given in µS/cm.

Production of demineralized water

Alfiltra offers complete water treatment systems for the production of demineralized water. These usually consist of a softening system or Penta filter system for well water, a reverse osmosis system and then a mixed bed filter. This is the most practical way to implement full desalination.

We would be happy to advise you by phone or email about our products for producing demineralised water.

Product: REOS Compact reverse osmosis system

The REOS Compact reverse osmosis system is primarily designed for the treatment of relatively clean, pre-filtered drinking water. While it is excellent at removing impurities, pollutants and microorganisms from water to produce pure drinking water, its suitability for producing drinking water directly from a body of water such as a river depends on various factors.

For the direct treatment of river water into drinking water, preparatory steps are usually necessary to remove coarse impurities and particles before the water is passed through a reverse osmosis system. This includes pre-filtration to remove sediment, suspended solids and possible larger organic materials that could damage or clog the reverse osmosis system membranes.

Furthermore, the process of reverse osmosis can also lead to a reduced pH value, making the water slightly acidic. This is because reverse osmosis systems not only remove impurities, but also minerals that give the water flavor and contribute to pH balance. In some cases, it is therefore necessary to post-treat the osmosis-treated water to increase the pH and add minerals back in so that it meets drinking water standards and preferences.
