Bord na Móna Environmental Products U.S., Inc. recently announced that the first U.S. installation of its new generation MÓNASHELL biological odor control treatment system has been completed at the T.Z. Osborne Water Reclamation Facility in Greensboro, N.C. The facility is part of the greater Greensboro Water Resources Department.

“The MÓNASHELL system was installed at T.Z. Osborne in early March,” said Bord na Mona Environmental Products U.S., Inc. President Shane Keaney, “and it is achieving the expected high performance results across the range of odor compounds in line with our experience on more than 500 Bord na Mona odor control systems installed throughout the world.”

According to Brendan Naples, odor product manager at Bord na Mona, odor emitted from wastewater treatment processes is increasingly a concern as populations grow and housing encroaches upon once-remote treatment facilities.

“Odor is more than unpleasant. It derives from sulfurous compounds that can raise acidity and cause corrosion,” Naples said. “The MÓNASHELL biofiltration system is a sustainable, low-maintenance and low-operating-cost alternative to traditional carbon or chemical scrubbing. 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.”

According to Naples, the system installed at the T.Z Osborne Water Reclamation Facility is treating 500 cfm of air containing very high concentrations of organic sulfides and H2S.

“The MÓNASHELL system is eliminating in excess of 99% of H2S, up to 99% of organic sulphides and in excess of 96% reduction on odor analysis using both ASTM E679 & EN13725 standards and it is doing so without chemical or nutrient additives, which is both better for the environment and keeps the operating costs lower,” Naples said.

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 requiring odor and VOC removal.

The waste airstream is treated biologically in the liquid phase through re-circulating water within the MÓNASHELL 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 physical, structural and chemical properties of the media allow for smaller filters and higher efficiencies. The byproducts of the system are harmless, clean and odor-free.
