    Abstract:
    In the Centre for Membrane Science and Technology (CMST), diverse research addresses a range of today’s environmental challenges in both water and gas separation. One of the areas of focus is recalcitrant micropollutants which poses a barrier to water reuse and potential for accumulation in the water treatment cycle. Laccase has been immobilized in titania nanoparticle and carbon nanotubes and combined with membrane separation to degrade a range of micropollutants. Biocatalysis has been extended to novel enzymatic fuel cells which offers the potential for generation of electricity from wastewater utilizing a single enzyme approach and configured to use filtration membranes as separators instead of Nafion. A second major challenge is the treatment of brine in which both membrane distillation and pervaporation offer a route to zero liquid discharge. Fouling, wetting, and stability are addressed for these emerging technologies. Both new submerged module designs and nanocomposite membranes are explored to treat brines up to 100 g/L salt concentrations in the presence of humics and divalent ions.
    Nanocomposite membranes for CO2 gas separation have also been extensively explored with the focus on enhancing performance of commodity polymers and inexpensive substrates and use of 1D, 2D, and framework nanofillers. New strategies using PDA-PEI coating to facilitate formation of metal organic framework gas separation membranes and coatings have been recently demonstrated, yielding very high gas permeation and molecular sieving for H2/CO2 and He/CO2. In parallel, immobilization of enzymes for CO2 capture and conversion using bio-inspired and metal organic framework materials offers another vast potential for expanding the scope for membrane contactors for flue gas and biogas treatment.
