摘要： Provided are an anti-microbial matrix and filtration systems containing the same. The matrix comprises a surface-modified inorganic component and a polymeric binder comprising particles having an irregular, convoluted surface. The surface-modified inorganic component comprises a reaction product of an anti-microbial component and an inorganic component. The anti-microbial component comprises a quaternary ammonium salt containing an epoxide group. A covalent bond is, for example, between the quaternary ammonium cation and a hydroxyl group of the inorganic component. The quaternary ammonium salt can be poly(methyldiallylamine epichlorohydrin). Further, the quaternary ammonium salt can have the formula according to I: (Formula I), wherein n is in the range of 5 to 24. The inorganic component can be diatomaceous earth. The polymeric binder can comprise ultra high molecular weight polyethylene (UHMW PE). Methods of making and using the same are also provided.

摘要： In one embodiment, the present disclosure provides fail-safe mechanisms for final filters. The fail-safe mechanisms of the present disclosure include a prefilter that is essentially transparent or translucent to TOC contaminants and a microporous filter downstream from the prefilter that filters contaminants by means of size-exclusion, mechanical interception, coagulation, or a combination thereof, the filter being adapted to significantly reduce fluid flow and undergo blockage under a challenge by TOC contaminants. In another embodiment, the present disclosure provides a method of filtration that includes the steps of providing a microporous filter disposed upstream from a final filter, the microporous filter capable of filtering contaminants from a fluid by means of size-exclusion, mechanical interception, coagulation, or a combination thereof, and said filter being adapted to significantly reduce fluid flow and undergo blockage under a challenge by TOC contaminants, and filtering the fluid through the microporous filter
