Removal of Microcystis sp. using ceramic powder = 분말세라믹에 의한 Microcystis sp. 제거효과

Abstract

The removal of Microcystis aeruginosa and Chlorella zofingiensis by ceramic powder was investigated on the basis of both the particle size (under 0.05, 0.1, 1 mm) and the dosage (0.1, 1, 10 g L-1) of the ceramic powder. The removal efficiencies of M. aeruginosa and C. zofingiensis were highest with a particle size of 0.05 mm and a dosage of 1 g L-1 of the ceramic powder in laboratory experiment. Chlorophyll-a concentrations decreased in both field and enclosure samples with a particle size of 0.05 mm and a dosage of 1 g L-1 of ceramic powder, resulting in the removal efficiencies of 67 and 69%, respectively. Consequently, it was concluded that the ceramic powder could be used to control algal bloom by removing chlorophyll-a in eutrophic waters.
