Abstract
A liquid purification system capable of separating a first liquid from a second liquid, in which the first liquid is a corrosive aqueous liquid that is wholly or partly immiscible in and forms a discontinuous phase with a second, continuous phase-forming organic liquid is provided including a housing, a fluid inlet in the housing, a first liquid outlet in the housing, a second liquid outlet in the housing, at least one coalescing assembly for coalescing the first liquid, and a liquid separating region in the housing. The coalescing assembly has at least one coalescing element which includes a halocarbon polymer packing material having a solid capture efficiency of as high as 20 .mu.m, is substantially chemically inert to corrosive liquids and is adapted to separate liquids differing in interfacial tension of at least about 0.6 dynes/cm. A coalescing element for coalescing a first liquid from a second liquid, in which the first liquid is a corrosive aqueous liquid that is wholly or partly immiscible in and forms a discontinuous phase with the second, continuous phase-forming organic liquid is also provided which includes a halocarbon polymer packing material having at least one porous, fibrous, non-woven web. The web having a solid capture efficiency of as high as about 20 .mu.m, and is adapted to separate liquids differing in interfacial tension of as low as 0.6 dynes/cm.
