Abstract

Un método para remover una parte esencial de los patógenos portados en el agua de un líquido acuoso contaminado con tales patógenos portados en el agua.El método incluye los pasos de pasar el líquido acuoso contaminado a través de un filtro mofidicado con carga químicamente compuesto de: 1) una hoja de filtroteniendo una pluralidad de materiales de filtro a base de sílice y fibras de celulosa expuestas individuales seleccionadas de particulados de sílice yfibras silíceas; y 2) modificadores de carga química catiónicos recubiertos sobre la superficie de la hoja de filtro. Cuando el líquido acuoso es pasado através del filtro modificado con carga químicamente, una parte esencial de los patógenos portados en el agua mayores de alrededor de 0.1 micras en tamano seadsorben sobre el filtro modificado con carga químicamente. El filtro es efectivo para remover el vibrión de cólera.A method of removing an essential part of the 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 charged modified filter composed of: 1) a filter sheet having a plurality of silica-based filter materials and individual exposed cellulose fibers selected from silica particulates and siliceous fibers; and 2) cationic chemical charge modifiers coated on the surface of the filter sheet. When the aqueous liquid is passed through the chemically loaded modified filter, an essential part of the waterborne pathogens greater than about 0.1 microns in size are adsorbed onto the chemically loaded modified filter. The filter is effective in removing the cholera vibrio.
