"The performance of ceramic membranes surface coated with cysteic acid to improve efficiency and reduce fouling rate was studied under two transmembrane pressure (TMP) and constant crossflow velocity (CFV). The filtration process was done in crossflow mode to allow for extended operation of the membranes. the performance of the membranes were determined in terms of the measured fluxes and on content rejection. Cleaning-in-place (CIP) was done on the membranes to ensure flux recovery after each run. The results showed significant improvement on the performance of the membranes with respect to high permeate fluxes and high oil content rejection (> 99.5%). When compared to other coating materials such TiO2 and graphene, cysteic acid presented exhibited better performance. Also, the effects of ionic strength on membrane performance was tested. Using 1000ppm oil in various ionic concentration solutions, results showed that ionic strength has a significant impact on membrane performance. Droplets sizes were impacted by ionic strength whereby as the ionic strength increased droplets size also increased as well as the permeate fluxes. These observations were explained in terms of viscous, electroviscous and solvation effects and pore size distribution"--Abstract, page iv.
