Fluid purification system

A filter for use in a purification system, said filter comprising a substrate having a plurality of cells and an oxidation catalyst suspended on said substrate so that the catalyst coats the walls of said cells, said oxidation catalyst comprising a mixture of nanophase metal oxide and microphase metal oxide, wherein said mixture contains at least 30% of said nanophase metal oxide, said oxidation catalyst electrostatically sprayed onto said substrate without the use of adhesives, said catalyst having properties so as to be able to decompose organic contaminants within a fluid by exposing said fluid to the oxidation catalyst in the presence of ultra violet light.

A filter for decomposing organic contaminants within a fluid, said filter comprising a substrate having a plurality of cells and an oxidation catalyst coated onto the walls of said cells, said oxidation catalyst comprising a mixture of first and second metal oxide solutions, said first metal oxide solution having substantially nanophase metal oxide particle size, said second metal oxide solution being substantially formed from a metal oxide having a particle size at least one order of magnitude larger than nanophase, wherein said mixture contains at least 30% of said nanophase metal oxide, said oxidation catalyst having the property of accelerating the oxidation of said organic contaminants when said oxidation catalyst is exposed to electromagnetic radiation, said substrate configured to support the nanophase metal oxide so as to maintain a high level of contact between the contaminants and the catalyst during fluid flow without substantially impeding the flow.

A filter for decomposing organic contaminants within a fluid, said filter comprising a pleated substrate having a plurality of cells and an oxidation catalyst electrostatically sprayed onto said substrate so that the catalyst coats the walls of said cells, said oxidation catalyst comprising a mixture of nanophase metal oxide and microphase metal oxide, said mixture formed by adding together a substantially nanophase component of metal oxide and a substantially microphase component of metal oxide, wherein said mixture contains at least 30% of said nanophase metal oxide, said oxidation catalyst having the property of accelerating the oxidation of said organic contaminants when said oxidation catalyst is exposed to electromagnetic radiation, said substrate configured to support the nanophase metal oxide so as to maintain a high level of contact between the contaminants and the catalyst during fluid flow without substantially impeding the flow.

A filter for use in a purification system, said filter comprising a pleated, wire mesh screen formed from a transition metal and an oxidation catalyst electrostatically sprayed onto said screen, said catalyst comprising a mixture of nanophase metal oxide and a metal oxide having an average particle size larger than nanophase, wherein said mixture contains at least 30% of said nanophase metal oxide, said catalyst having properties so as to decompose organic contaminants within a fluid by exposing said fluid to said catalyst in the presence of ultra violet light.
