Abstract
A method and device for the filtration and/or purification of fluids water or other solutions containing microbiological contaminants, such as fluids containing including bacteria and/or viruses, where the fluid water is passed through a purification material composed of apatite and absorption media in a fixed binder matrix.
Claims32
A purification material for fluids, wherein the material comprises apatite and a polymer material binder therefor, is in the form of a block or a sheet, and is sufficiently porous that fluids can flow through the purification material and separate microorganisms from the fluid or maintain the separation of microorganisms from the fluid.
A purification material for fluids, in the form of a block or sheet, comprising bone char, activated charcoal, and a polymeric binder material, that is sufficiently porous that fluids can flow through the purification material and separate microorganisms from the fluid or maintain the separation of microorganisms from the fluid, wherein said bone char and said activated charcoal are each present in amounts of about 42.5 wt %, and said binder is present in an amount of about 15 wt %, based upon the total weight of said purification material.
