Abstract

In this work, nanocomposite ultrafiltration (UF) membranes were synthesized through addition of different quantities of amino-functionalized nanocrystalline cellulose (NCs) in order to improve membrane anti-fouling resistance against oil depositions. The characterization results demonstrated that the overall porosity and hydrophilicity of the membranes were improved significantly upon addition of NCs despite a decrease in the pore size of nanocomposite membranes. The UF performance results showed that the nanocomposite membrane incorporated with 1 wt% NCs achieved an optimal water flux improvement, i.e., approximately 43% higher than the pristine membrane. Such nanocomposite membrane also exhibited promising oil rejection (>98.2%) and excellent water flux recovery rate of ˜98% and ˜85% after one and four cycles of treating 250-ppm oil-in-water emulsion solution, respectively. The desirable anti-fouling properties of nanocomposite membrane can be attributed to the existence of hydrophilic functional groups (−OH) on the surface of membrane stemming from addition of NCs that renders the membrane less vulnerable to fouling during oil-in-water emulsion treatment.
