Introduction: the conceptual regulations of the theory of sustainable socio-economic development provide the creation of resource-saving environmental friendly production, the basis of which are the effectively operating resource-saving water-use chemical processes (WUCP) of industrial plants. So, the objective of this investigation was the development of the designing methodology for scientific-reasonable resource-saving chemical processes of water management system for textile enterprises, which use the basic dyeing-finishing technology of cloth. Methods and materials: the thermodynamic exergy and thermodynamic water pinch methods of synthesis of resource-saving WUCP of industrial plants have been used and refined upon by us. The efficiency of proposed wastewater purification techniqueselectrocatalytic destruction, photocatalytic destruction, catalytic destruction by hydrogen peroxide, coagulation, clarification filtration, magnetic treatment was studied on model and real effluents. The metal oxides were used as catalysts. The special eperimental technique for development of technology of heavy metals ions utilization as useful products, such as mineral pigments, has been proposed. Results: a seven-steps scheme was investigated for project design: 1) the source data gathering: environmental-oriented analysis (inventory) of industrial enterprise's technology; 2) the design of integrated resource-saving water management system of industrial enterprise; 3) the design of repeatedly-serial water integrated chemical process system of industrial enterprise's shops (process lines); 4) the development of wastewater purification techniques; 5) the development of intelligence (computer) system of resource-saving water management system of industrial enterprise; 6) the technological risk assessment and safety management system; 7) the estimation of ecologic and economic efficiency of the project. Conclusion: the methodology of designing of resource-saving WUCP of textile enterprises has been developed. The functional diagram of resource-saving WUCP of dyeing-finishing production of textile plant has been proposed. The structure of intelligence system application and software of resource-saving WUCP designing and operation has been developed. Wastewater purification techniques have been investigated. The electrocatalytic plus photocatalytic destruction and coagulation methods are proved to be most perspective in practice of sewage treatment. The basic technical-economic parameters of the project were estimated.Keywords: methodology of designing water management systems, water-use technological processes, thermodynamic exergy method, thermodynamic water pinch method, wastewater purification techniques, electrocatalytic metod, technological risk, ecologic-economic effectiveness.
