BIOTON® biofilter

BIOTON® biofilter is Waterleau’s proprietary technology for the treatment of polluted air containing nitrogen or sulphur-based compounds.

This technology was acquired from MECS / CLAIRTECH.


The BIOTON® biofilter utilizes a fixed bed of a well-defined suitable mixture of inorganic / organic media, which contains the micro-organisms used to oxidize the nitrogen and sulphur based compounds contained in a polluted air stream.
