A biofiltration odor control system that uses waste sea shells to strip out odors will be featured at WEFTEC. The Mónashell® system from Bord na Móna Environmental Products is billed as a sustainable, low operating cost alternative to traditional carbon adsorption or chemical scrubbing.

The shell-based system is designed to for use at wastewater pumping stations, treatment works, sludge-handling and treatment processors, municipal solid waste and composting centers, as well as various industrial facilities.

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

The system is effective for treating a broad range of compounds and high levels of H2S and organic sulfides. It uses a smaller footprint than conventional biofilters and its offsite or onsite modular construction simplifies installation.

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 physical, structural and chemical properties of the media allow for smaller filters and higher efficiencies. By-products of the biofiltration process are harmless, clean and odor-free.
