Method of making a filter media with an enriched binder

摘要

Water filtration media having a charged material affixed directly to binder material used in the fabrication of the filter media. A microbiological interception enhancing agent is added to the binder directly. The media having a charged material and a microbiological interception enhancing agent both affixed directly on or in a binder material is then combined with core filter media and prepared as a filtration media. A filter is prepared from the treated filter media.

1. A method of making filter media comprising:
providing a charged material; providing a binder material; providing an anchoring agent solution for affixing the charged material directly to the binder material; combining together the binder material and the anchoring agent solution thereby infusing said anchoring agent with said binder material to form a binder-anchoring agent combination; heating the binder-anchoring agent combination to dry said binder-anchoring agent combination; crushing the dried binder-anchoring agent combination to form a binder-anchoring agent powder; mixing the binder-anchoring agent powder with the charged material; heating the combined binder-anchoring agent powder and charged material in a second heating step to form a charged binder material, whereby during heating the binder melts to attach the charged material to the binder while the anchoring agent forms insoluble polyelectrolyte complexes with the charged material to enhance the attachment of the charged material to the binder thereby forming said charged binder material; combining a core filter media with the charged binder material; and forming a filter media with the combined core filter media and the charged binder material.
