Study process treatment of Syrdarya and Keles rivers water of the Turkestan region

Over the past decade, all Central Asian countries have experienced a sharp increase in agricultural production, not only due to a reduction in investment in irrigated agriculture, but also due to a sharp deterioration in the condition of the water resources of irrigated lands. The purpose of this work is an environmental assessment of the state of the Syrdarya and Keles Rivers, as well as the development of methods for surface water purification. The results show that the water in the studied region, based on the main polar indicators, shows that irrigation water for irrigation was determined by the following chemical compounds: in Syrdarya HCO3, SO4, Cl, Ca, Mg, of . Cl -52.2 and Na - 73.5 in Keles rivers Cl -101.2 mg/l. A new membrane device design has been tested, which is suitable for continuous processes and solute separation, as well as for extending the life of the membrane. The relationships between water composition, operating pressure, and low velocity were established, and their effect on membrane permeability and selectivity was analyzed. With a selectivity coefficient of 0.8, the membrane system provides a capacity of 92 liters per square meter per hour. By the fifth regeneration cycle, the permeability was maintained at 70 l/m2·h, an acceptable level for long-term operation. The ratio between the regeneration efficiency and the drying rate has shown that 99% recovery is possible within one hour. This study is characterized by optimal conditions and operating modes for effective water dissolution, which contribute to improving the efficiency of membranes in practice.
