Also known as Biotowers, Biotricklers, Bioscrubbing Systems, Bioscrubbers, and Biological Oxidation Systems
KCH designs and manufactures a Biotrickling Filter System to remove high levels of hydrogen sulfide (H2S) gas and other odors from municipal and industrial processes. Our Biotrickling Filter Systems will effectively remove 99% of H2S without the use of dangerous chemicals. Instead of chemicals, a simple non-proprietary nutrient is used to promote biological growth on a synthetic media.
The standard KCH Biotrickling Filter System incorporates an integral sump box and pump circulation system built into the vessel. KCH Biotricklers can also be designed for a rectangular low-profile configuration, utilizing a structured high-density media.
These systems are constructed of POLYLAST®or POLYSTRONG® material, providing the structural integrity, UV protection, and corrosion resistance required for outdoor installations.

Biotrickling Filters use a synthetic media to support the growth of natural occurring micro-organisms to convert H2S into a dilute acid solution, part of which is discharged via a continuous water make-up or overflow. The Biotrickling Filter uses continues recirculation of a nutrient-rich solution to promote the biological growth. KCH offers a non-proprietary nutrient supplement to feed the micro-organisms and water to maintain the optimum pH.
