Reverse Electrodialysis Process in Heat Transfer with Energy

— In recent years, reverse electrodialysis technologies have become a special separation technology in the water and wastewater treatment industry. The main reason for the development of this technology is the absence of the use of chemicals, the simplicity and at the same time the high efficiency of the process compared to the electrodialysis process. In this research, the reverse electrodialysis process in heat or energy transfer is investigated. The purpose of this thesis was to perform reverse electrodialysis process in heat or energy transfer and it will be examined more closely as a suitable option for progress in the field of energy and heat transfer. The method of this study is library. First, data and information are collected through the study of various articles, and then the work is continued using the laboratory method, and the results of the laboratory method are analyzed and evaluated. In this study, using the results of the laboratory pilot test and the Taguchi method, the optimal conditions for performing the reverse electrodialysis process to produce electrical energy were determined according to the main effective parameters, including the difference in concentration, temperature, and flow rate of two solutions with different concentrations. It was found that the factors selected under the analysis affect the production of electric power with 95% confidence, and the concentration parameter is the most effective factor in the studied system. Also, the electric power produced at different temperatures and concentrations varies with the increase in flow rate, but this increase has a slower trend after certain limits. The results show the ability of the studied system to produce electrical energy from the difference in salinity concentration of two solutions and the possibility of using it in systems such as water desalination plants
