A slatted floor is mounted on a concrete floor with a plastic mesh on top, with 15 cm of Leca laid on top of this and finally 1 m3 BBK biofilter material per m2 on top. The biofilter material is inoculated with selected microorganisms. Sprinkler systems are installed to moisten the filter. The airflow with odorants is fed in at the bottom and pressed upwards and out as completely fresh air.
The temperature in the biofilter is maintained at an optimal 15-35 degree Celsius, which provides maximum purification effect and ensures that the active microorganisms effectively break down odorants.
Unlike many other biofilters, a BBK filter cannot be degraded and become inactive. Before the filter is inoculated with the specific microorganisms, we carry out a heat treatment that completely eliminates unwanted seeds, germs and other microorganisms. This ensures optimum odour elimination.
