| Abstract |
With increasing the insolation in summer, the blue-green algal blooms occurred periodically in the stagnant reservoirs and rivers in tropical and temperate regions. For mitigation, we employed the loess suspension techniques which have been used for the red tide control of Cochlodinium polykrikoides in the industrial scale in southern coast of Korea. Before applying this technique in situ, we tested the elimination effect of causing organisms, Microcystis sp., by loess suspension in 1 ℓ mass cylinder column test with different grain sizes and concentrations. As the grain sizes, the finer, the better; indifferent according to its origin but the applicable concentration was above 2,000ppm. |
