Study of a Reverse Electrodialysis Plant Operation on Industrial Liquid Waste

Reverse electrodialysis (RED) technology is one of the development directions in electrochemistry in the field of membrane processes, namely, electrodialysis, which is widely used in industry and has many areas of industrial use, including a well-developed direction of cleaning wastewater with various compositions. RED has expanded this range of applications thanks to the technology of wastewater treatment with simultaneous generation of electricity. Highly concentrated solutions suitable as working solutions for RED can be obtained as liquid waste in a number of industrial activities. In general, this is a promising prospect for RED as a reliable energy source, as soon as the technological problems are solved. The article presents an analysis of literature data on the use of industrial wastewater as feed solutions for reverse electrodialysis, as well as own experimental studies and results on the processing of liquid waste from a chemically desalting ion exchange water treatment plant of a thermal power plant with the generation of electricity by the reverse electrodialysis method.
