Abstract. The expediency setting the electric power consumption the sewage treatment processes is considered. The current world tendencies concerning the practical implementation energy management approaches with technical regulation based on the requirements of ISO 50001:2018 and other international standards are analyzed. The evaluation works the scientific schools in relation to the establishment of the effectiveness existing technical systems, in which it is assumed that energy in the technological process is necessary for action in the substance, which leads to the desired result. The method estimation the electric power consumption of the processes removal from aqueous solutions pollutants, which takes into account the technical complexity real time setting energy transformations in such environment, is substantiated. Only such electric energy indicators are used in this assessment, since they are integral to the assessment resource efficiency of the combined processes for the removal of pollutants: it is difficult (in fact not possible) to take into account the integrated energy characteristics physical (mechanical), biological, chemical, physico-chemical methods water purification, which is connected with their multifactor and constant energy transformations. The requirements of the scientific and technical principles Ukrainian normative documents in the context of the requirements ecological safety and existing technological solutions to their compliance with the water drain are systematized. The key influence electricity use on the production water purification is determined. According to the normative documents and statistical studies, the averaged recommended regime parameters aggregates are taken without analysis of the concentration pollution at the input and output of the corresponding processes. The electric power consumption wastewater treatment is analyzed and its significant values are determined, especially with combination different methods of the removing pollutants in a single system, for various types equipment, based on which the conclusions about the economic prospects creating the appropriate administrative methodological support on the basis of energy, ecological and risk management approaches are made.
Key words: electrotechnical water purification, international standard, energy management, energy efficiency, electric energy capacity
