Neutral pH
The Monashell biofiltration odor control system from Bord Na Mona Environmental Products Inc. reuses waste shells as media to maintain a neutral pH, allowing for biological treatment of odorous sulfur compounds without chemicals or nutrient addition.
The waste airstream is directed into re-circulating water in the unit, allowing contact between selected microorganisms and odorous compounds. The bacteria reside on the shell media, which contains high levels of CaCO3 and neutralizes acid byproducts of sulfide oxidation. The system is effective for treating a broad range of compounds and high levels of H2S and organic sulfides. 800/787-2356; www.bnm-us.com.
