What is demineralised water? Demineralised water is purified water from which most salts (minerals) have been removed. As a result, demineralised water does lose its buffering capacity, so the pH of demineralised water drops when it comes into contact with air, among other things. The advantage is that the conductivity of demineralised water and alkalinity decreases, and there is no longer any hardness (limescale) present. The main difference between osmosis water and demineralised water is that the conductivity of demineralised water is lower than that of osmosis water. Demineralised water is produced utilising a demineralised water system. Demineralised water is so pure that minerals such as salt and lime do not enter the techniques and settle. Grünbeck supplies demineralised water installations from a very small 125l/hour up to installations of >400m3/hour. Grünbeck’s installation is very compact; 140x40x50 cm and the conductivity of the demineralised water <9 mS/cm is perfe

Groundwater naturally contains iron. Once groundwater has been de-ironised, it is better suited for your product and installations. Iron in the water can have an unpleasant odour and/or taste, and it also increases the chance of rust formation in the installations through which the water flows. Water de-ironing is, therefore, an important form of water treatment. The most common techniques for de-ionising water are aeration (oxidation) and/or dosing an oxidising agent. Both methods ensure that both iron and manganese are removed from the water. At Grünbeck, we have developed a deferrization plant that uses the best technologies for deferring groundwater: the fermaliQ. This model combines oxidation with filtration, thus removing odours caused by hydrogen sulphide or ammonium.
