Research of filtration properties of clinoptilolite

The paper deals with the research of chemical resistance, mechanical strength, sorption and filtration properties of clinoptilolite, resulting in showing optimal parameters of clinoptilolite filtration process. It has been revealed that alkaline treatment of zeolite is more efficient than acid or salt treatment. Analyzing the results obtained, one can draw a conclusion that due to adsorption process on the basis of natural zeolite, salt hardness content has decreased, sulphate content has decreased, iron (III) content has declined, the concentration of chlorides and nitrates has declined, and organoleptic properties, clarity and taste of water have improved. As shown by the research performed in terms of the main physical and chemical adsorption characteristics, clinoptilolite conforms to the requirements applied to sorption filtration materials, which proves the possibility to use the zeolite, being researched, in the systems of water and wastewater treatment. The application of clinoptilolite can become a quite simple and inexpensive method to solve the problem of impurity removal, in particular, removal of ammonium compounds in the circuits of purification
