Description: The book outlines the principles of the formation of energy infrastructure equipment for water purification and regeneration systems in the complexes of technological lines and residential buildings belonging to the category of smart industries and smart homes. In these innovative complexes, in the water supply systems of which an integrative method of regeneration and subsequent recycling is used. It is only with electrochemical processing methods that technologies using elements of artificial intelligence and artificial neural networks are formed, as well as effective composite materials are used, including carbon-carbon compositions, from which categories of volumetric porous electrodes for electrochemical reactors are produced.
