MónaFil®

“Air Clean offers proven, proprietary clean air bio-technologies, which provide best-in-class process performance with the lowest utility and life cycle costs”

MónaFil® is an engineered organic biofilter media which is used almost exclusively on high volume airflows with low to moderate levels of VOC, H2S, Organic Sulphur, Ammonia and Organic Nitrogen compounds.
Control of hydrogen sulphide and VOCs is a concern in many wastewater treatment, composting and industrial plants: hydrogen sulphide, and many VOC’s, create odours, are corrosive, cause air pollution and can be detrimental to health.
The combination of excellent mechanical properties, longevity, uniformity and high airfilled porosity results in a long media life and allows for an installation depth of up 3m with a corresponding reduction in footprint. The resulting benefits from this technology are low footprint, high odor removal performance combined with low system pressure. Monafil delivers a low initial capital cost which in turn combined with the properties of the media yields low life cycle costs, particularly on large volume airstreams, due primarily to the low energy requirement and long media life.
