One of them is the adsorption method. Today the adsorption method is widely used in the water treatment industry. The aim of the research is to create an effective multifunctional filtering composition suitable for complex physical and chemical water purification. For this, a cation exchanger developed on the basis of local raw materials, activated alumina and other local materials was used. The adsorption properties of the cation exchanger and aluminum oxide in the composition of this filter have been studied. Also, the parameters of the filter for water purification are determined.6292021629202195101https://www.naun.org/main/NAUN/mechanics/2021/a202003-010(2021).pdf10.46300/9104.2021.15.10https://www.naun.org/main/NAUN/mechanics/2021/a202003-010(2021).pdfB.N.Frog, A.P.
