Abstract
Reverse Osmosis (RO) desalination is widely employed for freshwater production from seawater or brackish water. However, the process is energy-intensive, posing significant operational costs. The integration of Energy Recovery Devices (ERDs) has become a pivotal technique to optimize the energy consumption of RO systems. This manuscript explores the performance improvement of RO desalination systems by incorporating various ERDs, focusing on their operational principles, efficiencies, and impacts on system optimization. The study presents a comparative analysis of conventional RO systems against those integrated with ERDs, employing thermodynamic modeling and experimental data from literature till 2020. Results indicate energy savings up to 40% can be achieved, significantly reducing the specific energy consumption (SEC) while maintaining permeate quality. The research highlights key design considerations, limitations, and potential future enhancements for ERD integration in RO desalination plants.
