Abstract: The effect of potassium permanganate as preoxidant for algae-laden source water and the mechanism that it causes algae cells aggregation was investigated. Synthetic algae suspensions, prepared from lab-cultured Chodatella sp., were used for batch preoxidation and settling tests. In order to study the effect of water hardness on the function of permanganate, some algae suspensions were spiked with CaCl2 solution. Experiments with preformed MnO2 to look into its effect on algae cell aggregation were also conduct…
