Mónafil is a patented biofiltration system that uses special media as a capture and support medium offering excellent removal efficiencies for odors, VOC’s, sulfur and nitrogen-based compounds.

The properties of the manufactured granular high-density peat media have proven to be a key factor in achieving high performance removal and media life up to 10 years. 

Mónafil has been successfully used in odour control applications for more than 20 years.

CrumRubber™ is an ideal media with the capability to catalytically remove and convert H2S to sulphate. Typical removal efficiencies for levels from 10 to 200 ppm of H2S ranged from 30 to 70%.


Treatment efficiencies in excess of 98% was achieved on high H2S levels after years of R&D carried out on Landfill gas, treatment levels in excess of 2000 ppm were successfully treated with this technology.

The Mónashell biofiltration system is a proven and cost-effective alternative to chemical scrubbing or carbon adsorption, designed like a biotrickling system yet incorporating many benefits of traditional biofilters.

The shell-based media is sustainable and renewable with the ability to maintain a neutral pH within the biofilter. This ensures optimal odor performance across a broad range of odor producing compounds while simplifying operation and enhancing system reliability.
