Biofilter

A biofilter is used to decontaminate an environment by filtering impurities, which are sources of pollution.

Biofilters are currently used to treat polluted water. In this case, water is passed through a system composed of micro-organisms that capture and decompose the pollutant particles.

Biofilters to clean the air are also being developed (Phytair programme). The system should actively move air towards a plant wall. Plants would be selected for their depolluting capacities.
