CHEMICAL-FREE ODOR CONTROL WITH BIOTRICKLING FILTRATION
KCH Engineered Systems designs and manufactures a Biotrickling Filter System to remove high levels of hydrogen sulfide (H2S) gas and other odors from municipal and industrial processes. The system effectively and efficiently removes 99 percent of H2S without the use of dangerous chemicals. Instead, a simple non-proprietary nutrient is used to promote biological growth on a synthetic media.
The standard KCH Biotrickling Filter System, also sometimes called a bioscrubbing system, is a vertical, countercurrent vessel designed for continuous operation. 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.

CALIFORNIA PROVIDES LIMITED APPROVAL OF NON PFOS BASED FUME SUPPRESSANTS:
California limits the use of NON PFOS Based fume suppressants to only those approved by the State of California. Furthermore, certain OEM and DOD specifications will not allow process changes to NON PFOS based fume suppressants, requiring chromium electroplaters and anodizers to install control equipment like the Spectra U Chrome Mist eliminator.
