the other hand, the suspended substances that have densities near water are
hard to settle even they form large flocs.
I would like to show the pictures of “magnetic separation of water-bloom green
used in this experiment is the same as the above experiment.
densities of micro-organisms are very close to water and difficult to settle.
flocculated with fine powder of Fe3O4 (magnetic particle) by soy-protein based
and removed by magnet.
