Outline of Final Research Achievements |
MPC (2-Methacryloyloxyethyl Phosphoryl Choline) polymer and PEG (polyethylene glycol) polymer were used to coat MF PVDF membrane to make the surface of membrane hydrophilic and resistant to protein adsorption to the membrane material. A laboratory scale experiment revealed that both of the polymer coatings were effective in mitigating fouling more in the intermittent suction case compared to the continuous suction case. A simulation using a fouling model suggested that the coatings were effective in controling irreversible fouling caused by the accumulation of foulants inside membrane matrix.
