Efficient elimination of algal cells with simultaneous inhibition of algal organic matters release is vital for the safety of drinking water. TiCl3 as a coagulant was first applied for Microcystis aeruginosa removal in the present study. At the same dosage of 130μM, higher removal efficiency of 98.1% for algae cells was obtained in TiCl3 coagulation than 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 a crucial role in the TiCl3 coagulation, the reduction capacity of TiCl3 appears to be decisive for improving the algae removal efficiency. This study suggests that TiCl3 could be a promising coagulant for efficient removal of algae and inhibition of algal organic matter release.
