摘要

WaterWater usage in industry constitutes the largest share of water usage in industrialized countries. This water usage overpass agricultureAgriculture by far. A large part of water is consumed for process cooling but a non negligible part is used within the process as steam or pure water. More recently, green hydrogen expected production will contribute to highly increase the demand. Waste water can be barely reused in these processes which lead to poor recovery ratios even with a comprehensive mass integration effort. Recently, methodologies coupling mass and energyEnergy integration allowed showing that coupling waste heat with waste water allows upgrading waste water into distilled water thanks to thermal membrane distillationThermal water distillation. This novel technology has proven it ability to handle water with different concentration in minerals making it preferable to reverse osmosis when it comes to highly concentrated waste water.
