Development of a Complex Processing Technology for Xujaipok Water Located in Dehqonobod Region, Uzbekistan

Abstract

Water scarcity and quality degradation represent serious challenges for rural communities across Central Asia. The Xujaipok water source located in the Dehqonobod region of Uzbekistan contains elevated concentrations of dissolved salts, iron, manganese, and microbial contamination, making it unsuitable for direct human consumption without treatment. This study presents the development and evaluation of a multi-stage water processing technology specifically designed for Xujaipok groundwater. The integrated system combines coagulation-flocculation, rapid sand filtration, activated carbon adsorption, reverse osmosis, and ultraviolet disinfection into a unified treatment chain. Laboratory and pilot-scale experiments confirmed that the proposed technology successfully reduces total dissolved solids, turbidity, heavy metal concentrations, and coliform bacteria to levels compliant with WHO drinking water guidelines. The results demonstrate that this complex treatment approach is both technically effective and economically feasible for implementation in remote areas of the Dehqonobod region, offering a practical solution to the local drinking water problem.
