Engineered Applications of Carbon Nanotubes in UF and MF Membranes: Pretreatment in Seawater Desalination

For fouling resistance and high removal LPM technologies to compete with conventional water treatment processes, a new design of LPM is required. Next generation CNT-LPM membrane design will draw on the unique characteristics for high flux, low fouling, and high removal membranes incorporated with CNTs. The overall goal of this research is to apply the unique properties of CNTs toward the design of next generation LPM process for SWRO pretreatment. It is currently unknown how CNT (size, shape, charge, hydrophobicity, functional group) incorporated membrane (pore size, charge, and hydrophobicity) characteristics influence contaminant removal with seawater containing organic species and high ions.
