Abstract: The textile industry is one of the most water-intensive sectors of the economy. A large amount of water is consumed in the technological processes of washing, dyeing, printing and finishing fabrics. As a result of the implementation of these processes, wastewater of complex composition is formed, containing mainly dyes, surface-active substances (surfactants), mineral salts and other impurities. The discharge of effluents into water bodies without bringing their composition to the accepted sanitary standards is unacceptable. The cleaning methods that currently exist in the textile industry, such as adsorption, flotation, coagulation, zonation, etc., require large capital and operating costs and do not always provide the desired effect. Most of the methods practically do not allow preserving or trapping useful components from wastewater for reuse, therefore, recently both in Uzbekistan and abroad extensive research is being carried out and new physicochemical methods for treating wastewater are being developed, among which reverse osmosis occupies a special place and ultrafiltration.
