Current Project
My research project focuses on the nanostructuring of surfaces in order to reduce adhesion of mineral surface crystals. The direct application of my work is in the design of improved NF and RO membranes to enable more efficient desalination where scaling may be a problem (e.g., high recovery desalination and operation with source water of high scaling propensity).
My research involves the use of a quartz crystal microbalance (QCM) onto which a polyamide membrane is created by interfacial polymerization. The QCM is utilized to quantify the kinetics of surface crystallization for native and chemically nanostructured RO membrane surfaces. IN my research the polyamide surface is modified by an atmospheric-plasma induced graft polymerization, whereby tethered layer of polymer chains of the desired properties is created.
Based on the above study a set of appropriate surface modification conditions will be identified and in-house synthesized and commercial RO membranes will be surface st5ructured using our unique atmospheric plasma-induced surface graft polymerization. RO/NF studies in a laboratory desalination system will be carried out to evaluate the performance of the surface structured membranes.
