Biofiltration Odor Control

The MÓNASHELL Biofiltration System uses harmless bacteria that reside on the shell media to treat sulfur compounds without chemical or nutrient addition. The media contains high levels of CaCO3 and neutralizes acid byproducts of sulfide oxidation. The waste airstream is directed into recirculating water, ensuring contact between selected microorganisms and odorous compounds, such as those found in wastewater pumping stations, wastewater treatment works, sludge-handling, municipal solid waste and composting centers
