A fluid treatment system is provided having a low affinity for amide group-containing materials comprising a porous structure, fluid-contacting components, including means to retain the porous structure, and a surface-modifying polymeric material having a low affinity for amide group-containing mate

A fluid treatment system is provided having a low affinity for amide group-containing materials comprising a porous structure, fluid-contacting components, including means to retain the porous structure, and a surface-modifying polymeric material having a low affinity for amide group-containing materials, formed in situ and bonded directly to the surfaces of the porous structure and the fluid contacting components. A method of producing a fluid treatment system having a low affinity for amide group-containing materials is also provided, comprising contacting the components of a filtration system including a porous structure and fluid contacting components, the fluid contacting components including means to retain the porous structure, with a solution of a monofunctional monomer having at least one hydroxyl group, which monomer is capable of forming a polymer having a low affinity for amide group-containing materials, and exposing the components and the monomer to ionizing radiation to effect polymerization of the monomer at the surface of the components.
