<p>Gas-liquid contacting media treated with an aqueous-based cationic or non-anionic resin prevents scale build-up from forming on the surface of the media. The contact media is constructed from a fibrous web of materials, for example glass, impregnated with an aqueous-based cationic or non-anionic resin, preferably a polyamide-imide resin.</p> |
