Leveraging nanotechnology for next generation seawater desalination

NanoH2O advanced membranes for reverse osmosis (RO) desalination represent a new material that enhances current polymer-based membranes with the benefits of nanotechnology. These nanocomposite RO membranes represent a step-change in productivity through improved permeability while maintaining requisite salt and contaminant rejection. Since the original publication of this concept, further development and optimization of this membrane technology for seawater reverse osmosis (SWRO) has resulted in an enhanced flux of more than double that of a 22.7 m /d (6,000 gpd) commercial baseline with 99.7% salt rejection. Recent seawater field testing of an industry-standard spiral-wound element module including the TFN material combined with a fabric support base topped with a microporous polysulfone layer has supported current laboratory research findings.
