A NOVEL ZERO-DISCHARGE SUPERCRITICAL WATER-BASED WAVE ENERGY DESALINATION SYSTEM

This paper presents a sustainable and innovative wave-energy-based water desalination system combined with an emerging supercritical water process for a zero-liquid-discharge technology. There is growing demand for producing clean water. Within desalination technologies, reverse osmosis, one of the most popular methods, uses a semipermeable membrane that separates fresh water from pressurized seawater. However, this technology produces brine, which is harmful to the environment. Supercritical water desalination is employed here as a means of using the brine to extract more fresh water and eliminate this environmentally toxic output. Wave energy is integrated with reverse osmosis to provide direct seawater pressurization for the first stage in the process. This wave energy converter converts the motion of waves into pressurized water through a power takeoff unit.
