Abstract

the paper deals with the variant of partial diversification of water supply facilities where the surplus of electrolytically generated hydrogen produced by electrolysis of sodium hypochlorite - water disinfectant -can be used for heating of production facilities and nearby consumers, production of conditioned water for technological needs from atmospheric precipitations, which confirms the possibility of economically expedient participation of the water supply enterprise in forming the regional market.

Highlights

According to the definition of the Organisation for Economic Co-operation and Development (OECD), the environmental goods and services sector includes a set of activities aimed at producing goods and services to prevent, minimise and eliminate harm to the environment and to reduce anthropogenic pollution from natural resources [1]
Russia's lag in this area leads to limited economic growth potential and loss of competitive advantage
The introduction of resource and energy-saving technologies based on the utilization of electrolytic hydrogen, a by-product of the sodium hypochlorite production improves the operating system of water supply facilities, creates an additional source of heat and reduces the cost of the main technological process

Summary

Introduction

According to the definition of the Organisation for Economic Co-operation and Development (OECD), the environmental goods and services sector includes a set of activities aimed at producing goods and services to prevent, minimise and eliminate harm to the environment and to reduce anthropogenic pollution from natural resources [1]. The water sector in many developed countries around the world has long enjoyed the status of an environmental services sector This is due to the fact that its main task is the technological removal of pollutants from natural and waste water, and from gas emissions, bringing them up to standard levels. In the coming years the state of the operating system will become a key factor in the competitiveness of the entire country and of each Russian region separately This is indicated by clearly demonstrated trends in the global market for the "environmental industry", including the sectors of water supply, waste management, energy efficient technologies, energy saving and ecological equipment.
