TiO2 coated membrane surface characterisation with contact angle measurements

In this work a neat polyacrilonitrile ultrafiltration membrane performance was compared to a same but TiO2 coated membrane during oily water filtration. The fouling mechanisms of the two membranes and the resistances were determined and calculated.It was found that in case of the neat membrane initi...

The fouling mechanisms of the two membranes and the resistances were determined and calculated.It was found that in case of the neat membrane initially intermediate pore blocking occurs that is followed by cake layer formation. The TiO2 coating proved to be beneficial due to its fouling mitigating effect. With contact angle measurements the membrane wettability changes were monitored,whichoccurred as a result of the TiO2 coating, oily water filtration and cleaning of the membrane surface by UV irradiation. After 3 hours of UV irradiationthe water flux reached the neat membrane flux, but the residual oil layer on the surface still had a significant effect on the surface wettability.
