In recent years, the amount of water consumed by enterprises has increased dramatically and continues to increase. the pollution of existing water supply sources is continuously increasing, which leads to deterioration of the chemical and microbiological composition of water. Because of this, the composition of the water used by the enterprises is very diverse and, accordingly, it requires some regulation. In this article, modern methods of water preparation, which are use to sprout barley and influence of water parameters on germination of grain, are analyzed. In most malt plants, the quality used for technological needs of the water, especially the content of iron hardness salts and the pH value, is not optimal, which causes the need for various methods of water treatment: reagent ion exchange, electrodialysis and membrane, based on the principle of reverse osmosis. The ion exchange method is most suitable for water preparation in malt production, which involves processing it for the establishment of optimal ionic composition. This method of water preparation involves getting water free from magnesia, and at the same time there are salts of constant rigidity. In this method ion exchangers are used for water treatment. In order to soften the water use H- and Na-cation exchangers in which sodium cations and hydrogen are exchanged for calcium and magnesium cations of hardness salts.
