Objectives of the study
High-frequency algal blooms in Taihu Lake(East China) poses signif icant challenges to water resource management in basin. Coagulation based water processes have demonstrated great potential as in-lake measures to mitigate eutrophication and control algal blooms. However, the classical colloidal models and flocculation theories are not suitable for Microcystis Aeruginosa-dominated algae suspension. Therefore, the combination of a coagulant with a ballast to precipitate cyanobacteria from the water column was a new technology for surface scum blooms management in eutrophic lakes, which was known as “flock and sink”.
