Harnessing Clean Water from Power Plant Emissions

2020-1-13 · Power plants consume a major fraction of water to generate electricity, typically in the range between 30–50% of all fresh water sources. Most of the water from plants are lost with heat through stack and cooling towers. It has been reported that if 20% of this water can be recycled, power plants can be self-sustainable, allowing them to be located with higher flexibility. Membrane contactor
