Project Introduction: Open-source and intensive utilization of water resources and energy: By adding a pressure energy recovery device to the thermal membrane coupled seawater desalination system, the pressure energy of concentrated brine is recovered, which not only increases the energy utilization efficiency of the thermal membrane coupling system but also reduces the system's energy consumption while improving the water production rate. Innovation: TVC-RO thermal membrane integrated water production system; Introduction of high-efficiency energy recovery technology; Multi-factor analysis of energy, water volume, and water quality. Prospects: The water production rate can be increased by 5%, and the power consumption ratio can be reduced to 0.66kW·h/m3; The water production unit is modularized, with significant ecological and economic benefits; Technology can be extended to brackish water, wastewater and sewage treatment.
