The hydrophilicity of the membrane surface plays an essential role in improving membrane filtration performance. Better hydrophilicity could facilitate higher water permeation and prevent fouling phenomena. In this research, a green additive from ginger extract (GE) was employed to improve the polyethersulfone (PES) membrane hydrophilicity. The PES/GE membrane was fabricated via the phase inversion method by dispersing GE powder in PES/NMP solution using sonication followed by mechanical stirred. The influence of ginger extract (GE) on the PES membrane was characterized in terms of hydrophilicity, morphological structure, porosity, water permeation, chemical composition, and mechanical property. Water contact angle measurements showed that PES/GE membrane with 0.1% GE has the highest hydrophilicity. Scanning Electron Microscopy (SEM) indicated a porous finger-like structure on the cross-section membrane after the addition of GE.
