Abstract
The increasing demand for potable water, coupled with the depletion of freshwater resources and rising energy consumption in conventional desalination systems, has created a need for sustainable and energy-efficient water purification technologies. Conventional desalination methods often require significant electrical power and are unsuitable for remote or off-grid regions. To address these challenges, this study presents the design and performance analysis of a portable solar-assisted hybrid thermal desalination system integrated with Reverse Osmosis (RO) and Ultraviolet (UV) disinfection for the production of safe drinking water. The proposed system combines solar thermal desalination, solar photovoltaic-powered RO purification, and UV disinfection into a compact and portable unit. Solar energy is utilized to heat and partially desalinate the feed water, thereby reducing the salt concentration before RO treatment. The RO unit further removes dissolved salts and impurities, while the UV disinfection unit eliminates pathogenic microorganisms without the use of chemicals. The system was designed, fabricated, and experimentally evaluated under natural summer climatic conditions in Maharashtra, India. The performance of the developed system was assessed by measuring water quality parameters including pH, Total Dissolved Solids (TDS), salinity, electrical conductivity, turbidity, water production rate, thermal efficiency, RO recovery, salt rejection, energy consumption, and UV sterilization efficiency. Experimental results demonstrated a significant improvement in water quality, with TDS reduced from 35,800 mg/L to 47 mg/L, salinity from 35.2 ppt to 0.05 ppt, conductivity from 53,500 µS/cm to 82 µS/cm, and turbidity from 12.4 NTU to 0.3 NTU. The developed system achieved an average thermal efficiency of 36.4%, RO recovery of 48.2%, salt rejection of 99.87%, and UV sterilization efficiency of 99.93%, while producing approximately 0.27 L/h of potable water under the tested operating conditions. The experimental investigation confirms that the proposed hybrid desalination system is an efficient, environmentally friendly, and renewable-energy-based solution for decentralized freshwater production. Owing to its compact design, low energy requirement, and high purification efficiency, the system has significant potential for application in coastal regions, rural communities, disaster relief operations, remote locations, and off-grid areas where access to safe drinking water is limited.
