ABSTRACT:
An apparatus and method for treating dirty water or other liquids containing particles of varying size includes a magnetic treatment unit and a centrifugal separator through which the liquid flows as a stream in sequence. The magnetic treatment unit causes very small sized particles to agglomerate, nucleate or otherwise to be amassed into larger particles which are then more easily separated by the centrifugal separator.
