A filter material comprising an ultrafiltration ceramic membrane column and a coating. The surface of the ultrafiltration ceramic membrane column comprises a plurality of micropores, each of which has a pore size ranging from 50 to 100 nm. The coating is formed on the surface of the ultrafiltration ceramic membrane column by vacuum plasma sputtering, and comprises a catalytic layer composed of a plurality of nano catalytic particles selected from titanium dioxide particles. Zirconium dioxide particles, alumina particles or a combination of the foregoing. The filter material of the present invention can enhance the effects of filtering algae and microorganisms and is less prone to bio-clogging. |
