Beschreibung
Zusammenfassung:	Processes for treating a fiber substrate are disclosed. A fiber substrate comprising borosilicate with acidic functional groups. A metal salt solution is introduced to the fiber substrate. The metal salt solution includes cations having an ionic charge of +2 or greater. The pH of the metal salt solution may be adjusted, and the cations are deposited on the glass fibers. The treated fiber substrate may be utilized to form a filter media.
