Beschreibung
Zusammenfassung:	PURPOSE:To effectively separate red tide plankton, by adding fine ferromagnetic particles to water containing red tide plankton to adsorb said plankton by said fine ferromagnetic particles. CONSTITUTION:Fine ferromagnetic particles are added to water containing red tide plankton to adsorb said red tide plankton and, if necessary, a flocculant is added to said water while thus treated water is passed through a first magnetic filter to collect said ferromagnetic particles. After a definite time, the first magnetic filter is washed and washing water containing red tide plankton and the fine ferromagnetic particles is passed through a second magnetic filter to separate the fine ferromagnetic particles and the red tide plankton. The separated fine ferromagnetic particles are re-utilized while the red tide plankton receives dehydration and concn. treatment.
