The problem of provision of the population with high-quality drinking water is currently one of the most topical in connection with the unsatisfactory technical condition of the existing water supply systems and pollution of the water sources. Natural zeolites, which have a sufficiently high sorption capacity, cation-exchange properties, relatively low cost and availability, are increasingly being used in recent times for water purification. The mineralogical properties of natural zeolites of the Tayzhuzgen and Shankanai deposits have been investigated. A comparative study of the sorption properties of the natural and modified zeolites of the Kazakhstan deposits has been carried out on model solutions, containing iron ions (Fe2+). The exchange mechanism and the degree of extraction of ions from the solutions have been established. The efficiency of the municipal water purification in the Auezovskiy district of Almaty with zeolites of the Shankanai field has been equal to 85.94%. This suggests a possibility of using these zeolites to purify water from iron ions with the purpose of water treatment in the dairy industry.

In the modern world, there are practically no sources of clean water suitable for human consumption. As a result, at any enterprise in the food industry a number of sequential operations are carried out related to the purification of water necessary for the production of products. In all processes of processing dairy raw materials, water supply to enterprises is carried out from a public water supply network and / or from an artesian well. The article discusses the feasibility of using natural zeolites to ensure water safety. Research data of Kazakhstan zeolites of various deposits and their application in practice were studied.. As shown by the results of experimental studies, zeolites of the Taizhuzgen deposit significantly improve water quality. As a result of activation, the sorption ability of zeolite rises to 85-90%. Production tests of zeolites indicate the significant potential of this mineral raw material. Natural zeolites are cheap, resistant to mechanical wear and can be reused after regeneration. Studies have shown that Taizuzgen zeolite is a good sorption material and can be recommended in further studies with the aim of developing filters for water purification used in water treatment processes in the dairy industry.
