Abstract
A method and apparatus for carrying out a method for thermophoretically removing particles from a particulate containing liquid the method including providing a heated turbulent flowing particulate contain liquid through a first conduit; redirecting a portion of the particulate containing liquid through a second conduit to provide laminar flow having a flow direction substantially parallel to the first conduit; forming a thermal gradient in said second conduit substantially perpendicular to the flow direction; concentrating particles in the particulate containing liquid in a portion of the second conduit aided at least in part by thermophoretic forces; and, separating the particulate containing liquid into at least a relatively concentrated particle containing portion and a relatively unconcentrated particle containing portion.
