Method and system for separating lipophilic substances.

摘要

System and method for separating lipophilic substances which may be either contaminants or useful substances contained in a liquid medium by means of a floating filter layer consisting of particles or flakes of irregular shapes. Oil matters covering the surfaces of such particles or flakes catch lipophilic substances contained in a liquid medium, and the oil matters are eventually removed from the floating filter layer either spontaneously through a supply of fresh oil matters from the liquid medium or intentionally by supplying fresh oil matters to the floating filter layer. The removed oil matters are either discarded along with the undesirable substances with which they are impregnated or further processed to obtain useful substances contained therein. Optionally, the oil matters may be recycled.
