SUMMARY
The object of research is the environmental safety of wastewater treatment plants while minimizing resource costs for the implementation of technological processes for the removal of pollutants from effluents. There are factors that comprehensively create the prerequisites for the inefficiency of activities to maintain the environmental safety of wastewater treatment systems, and, accordingly, the complexity of implementing their technical regulation. These factors include:– lack of real –time information on a specific combined process of water treatment, the complexity of its adequate research, even in laboratory conditions;– lack and/or low accuracy and speed of modern technical means of measuring the composition of aqueous solutions, especially in industrial conditions.Elimination of the influence of negative factors is achieved by improving the scientific and theoretical foundations for the creation of technological regulations for wastewater treatment plants while improving the environmental safety of industrial facilities, taking into account the requirements for reducing resource costs according to the concept of synthesis of environmental management systems.The environmental and energy criterion for assessing the functioning of wastewater treatment facilities is substantiated and analytically obtained. An analysis of the results of production implementation allows to state that the environmental and energy criterion, which shows the specific energy consumption for ensuring the environmental safety of water treatment, is acceptable to use when setting up industrial water treatment systems and creating their technological regulations. During the month of production research, the value of the environmental and energy criterion had deviations from the set by ± 3.4 %, which is a technologically acceptable indicator.An improved concept for setting integrated goals for achieving environmentally friendly sanitation in accordance with international systems for assessing the quality of enterprise management on the basis of environmental and energy criteria creates the prerequisites for obtaining an ISO 14001 certificate. Implementation of environmental management systems will provide:– reduction of financial expenses due to saving of natural resources and reduction of penalties;– profit growth due to potential implementation of reuse of water resources.
