Biofilter

Biofilters are currently used for various tasks pertaining to exhaust air cleaning. 

The biofilters manufactured by Wallstein distinguish themselves through natural inorganic substrate, which enables, for instance, usage in acidic environment for separation of hydrosulfides without degradation of filter material. This eliminates the need to periodically replace the filter material.

Biofilters made by Wallstein are used for deodorization in purification plants, as well as for desulfurization of biogases.
