HydroP is developing a material for seawater desalination membranes. The company has created a proprietary material to be added to desalination reverse osmosis membranes during fabrication. The tailored material impacts the water's thermodynamic property, leading to a reduction in the concentration gradient between the two sides of the membrane. The material drives an increase in output water flux without affecting salt rejection, resulting in an improvement to the membrane's energy efficiency and a reduction in the cost of desalination.
