FO could reject combined and single tannic acid and alginate foulants effectively.
- class="label">•
Greater tannic acid in the mixture deteriorated FO fouling flux and retention.

Higher initial flux and calcium ion strength promoted combined organic fouling.

The tannic acid foulants penetrate into porous membrane layer and thus enhanced ICP.
