What are Dioxins and Furans?

Dioxins and furans are halogenated aromatic hydrocarbons, a class of substances that share a similar chemical structure. Most are created unintentionally as a by-product of chemical manufacturing or incomplete combustion.

Common sources include the bleaching process used in pulp and paper processing, the manufacture of weed and pest control products, also solid waste incineration, power generation and metals smelting and refining.

Dioxins readily attach to dust particles, which is how they circulate in the environment.

How to Remove Dioxins and Furans

Tri-Mer’s UltraCat catalytic filter system is an effective technology for the elimination of these toxic air contaminants at the source. The nano-catalyst technology in Tri-Mer filters destroys these toxic compounds with efficiencies of 97% to 99%.

The low temperature catalyst of the Tri-Mer ceramic filters is ideally suited to high efficiency dioxin removal. It is a superior alternative to activated carbon in that it does not require an injection device AND is a “true solution.”

Activated carbon simply moves dioxin into the fly ash; the dioxin-laden fly ash then requires further treatment. The UltraCat catalytic filter system solves the problem definitively and efficiently.

Optimum dioxin control is limited to an upper temperature of 500°F if there are constituents such as chlorine, fluorine, and other halides that facilitate the re-formation of dioxins. If these have largely been removed upstream through the injection of dry sorbent, permanent dioxin destruction will occur at higher temperatures as well.
