Abstract： In the context of the escalating global energy crisis and climate change，addressing the crisis of freshwater scarcity，a hybrid thermal-membrane desalination system was proposed.Mathematical and economic modeling of reverse osmosis （RO）and multi-effct distilation（MED）seawater desalination was established，and fourdifferent coupling process schemes were presented based on energy and material flows. The various coupling process schemes were optimized under winter and summer operating conditions.Comprehensive analysis of thecoupling process schemes revealed that under winter conditions，scheme three with an RO to MED water production ratio of 8：2 was the most economically viable，with a water production cost of O.81USD ⋅m-3 ，leading to reductions of 26.3% and 13.8% in water production costs compared to standalone RO and MED processes，respectively. Additionally，the process exhibited a high freshwater recovery rate，reaching 65.4% . The hybrid thermal-membrane desalination system process studied can be further integrated with renewable energy sources to achieve improved economic and societal benefits.
