摘要

Humic acids (HA) didn’t cause obvious reverse osmosis (RO) membrane fouling in 45 h.

Osmotic pressure (NaCl) affected slightly the RO membrane fouling behavior of HA.

Ca2+ promoted aggregation of HA molecules and thus aggravated RO membrane fouling.

Ozonation eliminated the effect of Ca2+ on the RO membrane fouling behavior of HA.

The change of the structure of HA was related to its membrane fouling behavior.
