Study of Humic acid adsorption on Nanofiltration membranes by contact angle measurements

摘要

Membrane fouling is a major problem, which extent depends on the respective natures of the solute and membrane material. Membrane surface characterization under different fouling conditions may help in understanding the fouling mechanism. Such characterization was performed for the case of humic substances filtered on two nanofiltration mem- branes, using special contact angles measurements.
