Abstract
A filter system for removing contaminants from oil based industrial liquids and the like includes a support tube with a permeable sidewall through which the industrial liquid flows in an inside out direction. A multilayer coalescence media surrounds the support tube, and includes at least one layer of a non-woven fibrous material that is partially wettable by the dispersed water in the industrial liquid, and commences coalescence of the same to form small primary water droplets, and at least one sheet of a precisely woven monofilament fabric stacked on the downstream side of the non-woven material. The woven fabric is substantially wettable by the dispersed water, and has a fixed open mesh with uniformly sized and spaced apart pore openings which continue to coalesce the primary water droplets into large water drops which fall from the filter for collection along the bottom of the apparatus.
