Removal of Suspended Substances by Coprecipitation-Floatation method

摘要

Water pollution by aoko (microcystis) is often a problem in lakes and ponds. We aimed at the development of a new method of combining coprecipitation with the hydroxide iron and the floatage separation by the bubble as a removal of aoko (microcystis) and the suspension substances. In this research, a basic condition of the method was examined. The surface-active agent and the protein were examined with the material by which the bubble was put out, therefore the casein was excellent in the combination with the hydroxide iron coprecipitation in pH8. Moreover, when having experimented by using the suhara pond water with the model water tank, it was a removal rate of 66.3%.
