Discontinued product


The BTF-Bioscrubber​ bio-trickling filter (BTF) is an advanced, non-hazardous biological air treatment system which integrates equipment, media, and the NUCIRC process for optimal performance and flexibility. The NUCIRC process skid allows operation in either recirculation or once through modes to deliver accelerated acclimation that is ideal for odor control and removal.

The BTF-Bioscrubber system is designed to perform at efficiencies of greater than 99 percent of H2S removal and 95% odor without the need to add chemicals.
