Abstract
Efficient elimination of algal cells with simultaneous inhibition of algal organic matters release is vital forthe safety of drinking water. TiCl3 as a coagulant was first applied for Microcystis aeruginosa removal in the presentstudy. At the same dosage of 130 M, higher removal efficiency of 98.1% for algae cells was obtained in TiCl3 coagulationthan 64.5% for TiCl4, and the same trend was observed in turbidity and dissolved organic compound removal. Owing to the low reduction capacity of TiCl3, a low damage cell ratio was achieved. While charge neutralization plays acrucial role in the TiCl3 coagulation, the reduction capacity of TiCl3 appears to be decisive for improving the algaeremoval efficiency. This study suggests that TiCl3 could be a promising coagulant for efficient removal of algae andinhibition of algal organic matter release.
