Mόnashell Odor Control Biofilter
Overview
The Mónashell® odor control 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 a media maintains neutral pH in the biofilter, allowing for highly effective biological treatment of odorous 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 system, allowing contact between selected micro-organisms and odorous compounds. Harmless bacteria reside on the shell media, which contains high levels of CaCO3 and neutralizes acid byproducts of sulfide oxidation.
Mónashell is designed to deliver significant, environmentally responsible benefits for wastewater pumping stations, wastewater treatment works, sludge-handling facilities, municipal solid waste and composting centers as well as various industrial facilities needing VOC reduction.
Mónashell is very effective for treating a broad range of odor compounds, and high or variable levels of H2S and Organic Sulfides.
In addition to superior odor removal performance, additional advantages include
- low whole life costs
- a smaller footprint than conventional biofilters
- low water usage
- modular construction for ease of installation
How it works
-
Containment
Odors are emitted from waste streams with high concentrations of sulfur and other odorous compounds that undergo turbulence through pumping, filling and transfers. Odor sources in the treatment process must be located and contained using covers or other structures. The odorous gases can then be ventilated from the source to treatment.
-
Ventilation
Depending on the concentration of odorous compounds and the volume of air to be extracted from each source, ventilation is achieved via ducting and extraction fans under low negative pressure conditions. The airstream is pulled through the system, rather than pushed, decreasing the risk of escaping odors.

Mónashell® Biofiltration
The waste airstream is directed through the shell bed of the Mónashell® unit, allowing contact between the shell media, water, selected micro-organisms and odorous compounds. Harmless bacteria reside on the shell media, which contain high levels of CaCO3 and neutralize acid byproducts of sulfide oxidation. The physical, structural and chemical properties of the media allow for smaller filters and higher efficiencies than conventional biofilters. End-products of Mónashell® are harmless, clean and odor free.
