Abstract

A method of removing a substantial portion of waterborne pathogens from an aqueous liquid contaminated with such waterborne pathogens. The method includes the steps of passing the contaminated aqueous liquid through a chemically charge-modified filter composed of: (1) a filter sheet having a plurality of individual exposed cellulose fibers and silica based filter materials selected from silica based filter materials selected from silica particulates and siliceous fibers; and (2) cationic chemical charge modifiers coated on surfaces of the filter sheet. When the contaminated aqueous liquid is passed through the chemically charge-modified filter, a substantial portion of the waterborne pathogens greater than about 0.1 micron in size are absorbed onto the chemically charge-modified filter. The filter is effective at removing Vibrio cholerae.
