Cyanobacterial bloom has become a serious environmental threal throughout the world. In par-ticular, the presence of microcystes (MCs), has become a severe problem. Thus, it is essential to develop technologies for removing cyanobacterial cells and cyanotoxins simultaneously. In the present study, a calcium-hydroxide-modified, autoclaved fly-ash brick powder flocculant was developed. The factors influencing the removal of Microcystis aeruginosa by the modified flocculant, including the calcium hydroxide concentration, the particle size of the a...
