From cottonseeds grown in Uzbekistan, cottonseed oil is obtained by pressing and extraction. In the adsorption purification of cottonseed oils, percolation clays imported from abroad are used, and the natural minerals of Uzbekistan have not yet found practical application as an adsorbent. The authors tested the adsorption purification of cottonseed oil with an adsorbent obtained from the natural mineral kaolin Sultan-Uvais and obtained positive results. In order to use waste from the production of adsorption purification of cottonseed oil rationally, fatty adsorbents
obtained from Sultan-Uvais kaolin were used in the work to create a nutrient medium for chlorella algae. The technology of growing chlorella algae has been improved. The growth of productivity, pH value, electrical conductivity and organoleptic characteristics of the obtained samples of chlorella algae were studied.
