AbstractLarge differences occur between the removal efficiencies (RE) of polyaluminum chloride modified clay (PAC-MC) suspensions prepared using deionized water (DW) and seawater (SW). This showed that physicochemical properties of PAC-MC suspension influenced its ability to remove algal cells. The efficiency at which a PAC-MC suspension removed Aureococcus anophagefferens (CCMP 1984) and Phaeocystis globosa from water was determined using diluted seawater (DSW), dissolved ion species, ion concentrations, pH, temperatures, and suspension aging times. The RE decreased generally as the percentage of seawater increased, and the RE was higher for PAC-MC prepared using DW than that using SW. The ion species present and the ion concentrations in the suspension influenced the RE, with sulfate negatively affecting the RE more than the other ions tested. Sulfate in the PAC-MC suspension showed a "V"-shaped effect which can be partially explained by charge neutralization and "patch coagulation" that played different parts in the flocculation process. The effects of pH of PAC-MC suspension on the RE were greatly influenced by the dispersion medium. The RE of the PAC-MC suspended in DW decreased gradually, whereas RE of the PAC-MC suspended in SW followed a V-shaped trend, as the pH was increased. Surface charge is an important aspect in the removal mechanism of PAC-MC, but the flocculation behavior at low suspension pH conditions is less clear. Temperature and suspension aging time had no obvious effects on the RE. Appropriate explanation and mechanism is also proposed in the discussion. These studies showed that the RE could be further improved given proper attention to the properties of PAC-MC suspension.
