Abstract: A liquid purification system is provided which is capable of separating a first liquid, that is wholly or partly immiscible in and forms a discontinuous phase with a second, continuous phase-forming liquid, from the second liquid, which includes at least one coalescing element or assembly for coalescing the first liquid having at least one fluid inlet at the top thereof; and at least one separating element or assembly for separating droplets of the first liquid from the second liquid, the at least one coalescing element or assembly being arranged in superposed and fluid communicable relationship above the at least one separating element or assembly

Abstract: The invention disclosed is an improved scrim means for use in a breathing gas filter assembly which includes a pleated web filter medium. The improved scrim means is of a non-woven microorganism resistant synthetic polymeric material of sufficient rigidity to provide substantially continuous support to maintain the pleats of the filter medium in substantially uniformly spaced relationship, to expedite fluid flow in the plane of the web and to minimize nesting of the filter medium.
