Abstract:
1. A filtration system comprising: a filter medium that removes particulate contaminants from a fluid by diffusion, said filter medium including membranes, nanofibers, or small particles and powder immobilized in a solid structure including an interception enhancing agent comprising a cationic material having a counter ion associated therewith, wherein a biologically active metal is precipitated with the counter ion in direct proximity to the cationic material; means for providing sufficient contact time for an influent to contact said filter medium such that said filtration system operates at an average flow rate sufficient to achieve a particulate reduction target performance and below a flow rate required by a downstream requirement for a purified fluid; and a storage buffer, downstream from said filter medium, that allows the purified fluid to be supplied at the flow rate required by the downstream requirement for a purified fluid.
