The KERASORB fluorine filter from LTB is a moving bed filter for the sorption of von hydrogen fluoride (HF). As opposed to the other dry sorption processes from Lufttechnik Bayreuth, it features a
robust construction without filter inserts. Sorption takes place on limestone granulate, which comes in contact with the emission in cascades. The calcium fluoride reaction product can be disposed
of without a problem at construction waste sites.
