New biofiltration technology proves efficient solution for VOC emission control
Tri-Mer system has proved to be a practical alternative to thermal oxidizers, in-bed biofiltration, and aerobic digestion for the control of VOC emissions from virtually all sources. This new biofiltration-based VOC control alternative combines the best characteristics of an in-bed bioscrubber and aerobic digestion with the high removal efficiency of micron-scale mist scrubbing. The system treats high inlet concentrations of VOC emissions and is effective against a broad spectrum of VOC emission types. Alcohols, including methanol and other high vapor pressure VOCs, are simultaneously treated along with more difficult VOC compounds such as turpenes, pinenes, methanol and terpenes. Formaldehyde emissions, perhaps the most problematical from a regulatory perspective, are readily removed by the system. The system is highly flexible and is engineered to specific customer requirements; however, its underlying design philosophy always focuses on MACT compliance. Unlike the large, in-bed biofilters approach of the past, this new technology can be sited close to the emission source, minimizing the cost and complexity of long duct runs. Its tower configuration has a small footprint that can be adapted to the space constraints of virtually any facility.
