MÓNASHELL® Biofiltration Odor Control System


Source: Anua - Bord na Móna Limited

With over 600 references the MÓNASHELL Biofiltration System is a sustainable, low maintenance and low operating cost alternative to traditional carbon or chemical scrubbing systems and exhibits many advantages over other biofilters.

The reuse of waste shells as media maintains a neutral pH, allowing for highly effective biological treatment of odorous sulfur compounds in wastewater and industrial airstreams without the use of chemicals or nutrient addition.

The waste airstream is directed into recirculating water within the MÓNASHELL unit, allowing contact between selected micro-organisms and odorous compounds. The harmless bacteria reside on the shell media, which contains high levels of CaCO3 and neutralizes acid byproducts of sulfide oxidation.

The MÓNASHELL system is designed to deliver significant, environmentally responsible benefits for wastewater pumping stations, wastewater treatment works, sludge-handling, municipal solid waste and composting centers, as well as various industrial facilities included VOC reduction.

MÓNASHELL is very effective for treating a broad range of compounds and high levels of H2S and Organic Sulfides. MÓNASHELL provides a very low whole life cost solution, uses a smaller footprint than conventional biofilters and its offsite or onsite modular construction allows ease of installation.
