Abstract: A filter media suitable for use in filtering fluids is provided. The filter media comprises a filtration particle, said filtration particle having an Al2O3 content of from 15 wt % to 70 wt % and a SiO2 content of less than 70 wt % based on the weight of the particle.

Abstract: A filter media suitable for use in filtering fluids is provided. The filter media comprises a first component, said first component having a core with an Al2O3 content of at least 10 wt % and a nanoalumina coating that at least partially coats the core.

Abstract: 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.
