Abstract
A filtration apparatus includes at least one tangential filtration module ving at least one filtration element defining a conduit arranged in a spiral configuration within an enclosure in the form of a body of revolution. The element defines a helicoidal slope for liquid to be filtered and causes such liquid to pass through the module along a helicoidal path. The liquid is tangentially filtered, and filtrate is delivered to the exterior of the module.
