A coalescence media for separation of water-hydrocarbon emulsions comprising an emulsion-contacting sheet formed as single dry layer from a wet-laid process using a homogenously distributed, wet-laid furnish including two or more constituents of the group consisting of: (1) up to about 80% cellulose or cellulosic fibers; (2) up to about 50% synthetic fibers; (3) up to about 60% high-surface-area fibrillated fibers; (4) up to about 70% glass microfiber; (5) up to about 80% of a surface-area-enhancing synthetic material; (6) up to about 5% of a wet-laid-paper, dry strength additive; (7) up to about 5% of a wet-laid-paper, wet strength additive; (8) up to about 30% of a strength-enhancing component; and (9) up to about 30% binder resin for the finished sheet (where percent denotes percent of dry weight of the finished sheet).

Filtration media is comprised of a mixture of glass and synthetic polymeric fibers. Binder fibers are also preferably incorporated into the mixture of glass and synthetic polymeric fibers so as to achieve a structurally coherent mass of such fibers. Most preferably, a combination of thermoplastic and at least partially water soluble binder fibers will be present in the fibrous filtration media of this invention so as to promote structural integrity during processing and end use applications. In this regard, the fibrous filtration media is preferably made by wet-laying an aqueous slurry mixture of glass fibers and synthetic fibers onto a foraminous forming member (e.g., a forming wire) using conventional Fourdrinier or foam-type fiber wet-laying processes. Thereafter, the slurry mixture is dewatered to form a fibrous dewatered sheet of the glass and synthetic fibers. If present, the binder fibers are physically dispersed in the slurry mixture when laid onto the forming member. The sheet or mat or dewatered fibrous filtration media may then be subjected to elevated temperature so as to at least partially plasticize the thermoplastic binder fibers and thereby bind the glass and synthetic fibers at respective crossing points upon subsequent cooling.
