Synergistic fouling behaviors and mechanisms of calcium ions and polyaluminum chloride associated with alginate solution in coagulation-ultrafiltration (UF) process

•alginate specific filtration resistance (SFR) had a unimodal trend with Al3+ or Ca2+ addition alone.•Ca2+ and Al3+ had synergistic effects to reduce alginate SFR and fouling.•initial binding Ca2+ and Al3+ ions to alginates formed special geometries, increasing SFR.•Ca2+ and Al3+ sequentially elonga...
