PULP & PAPER

There are three general groups of odor producing compounds that come from pulp and paper industries: Reduced sulfides, ammonia, and other organic compounds. While the EPA had determined that Total Reduced Sulfur (TRS) odors are not a health concern, they are classified as a nuisance odor due to their low “odor threshold” meaning they are easy to smell in extremely low concentrations. According to the EPA, the odor threshold of TRS gases is approximately one part per billion i.e., one particle of TRS is gas is detectable in the human nose in one billion parts of air.

 

For those fugitive airborne malodors that may nonetheless escape into the air stream, our waterless vapor-phase system can be highly effective in reducing and eliminating malodors before they reach inhabited areas. For a detailed description of our waterless vapor-phase system, please click here.
