The Tri-Mer system serves as a practical alternative to thermal oxidizers, in-bed biofiltration and aerobic digestion for the control of VOC emissions from a wide range of sources. Tri-Mer says this 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 Tri-Mer system treats high inlet concentrations of VOC emissions and is effective against a broad spectrum of VOC emission types.
