Abstract
An inverted fluid vortex is created by an impeller within an inverted funnel. Heavier than water particles are forced outward and downward by the interplay of centrifugal, centripetal, gravitational forces and the internal downward cant of a funnel. A vortical fluid apex is suctioned from the system as necessary to keep the volume of the vacuum portion of the system constant and therefore the vacuum pressure constant.
