• Current research and development of standalone and hybrid desalination technologies. • Mathematical models were developed for hybrid MED-RO desalination system. • The key parameters influences on RO process in hybrid system were analyzed. • The optimal design and operational parameters of hybrid system were achieved through simulations and sensitivity analysis. • Engineering application and analysis of hybrid MED-RO desalination system based on actual operation data. Based on the current research, the hybridization of desalination technologies has proven to be an effective method of enhancing system performance, minimizing energy consumption, and reducing product water cost. This study focuses on a hybrid MED-RO desalination plant in a large coastal steel enterprise situated in Northeast Asia, China. A comparative analysis of distinct hybrid systems was undertaken, followed by the selection of an optimal process route that aligns with the site-specific conditions and the requirements of downstream freshwater users. To investigate the influences of feed and operational factors on RO process performance, mathematical models were developed for water balance, RO module performance, energy consumption, and economic indicators. Furthermore, according to actual plant conditions, the software simulation and cost benefit analysis were performed for the hybrid desalination system sensitivity analysis and optimization. The outcomes including permeate qualities, concentrate salinity, s...
