Tri-Mer Corp introduces the MultiPhase BioSystem, for VOC control. The MultiPhase incorporates both air phase and liquid phase approaches, taking advantage of the natural tendency of VOCs to partition into both phases. It uses proprietary media, and enhanced bioremediation techniques to treat high inlet concentrations of VOC with efficiencies up to 98%. MultiPhase uses permanent, synthetic ceramic biomedia, which is surface-modified to allow accelerated attachment and growth, has a very high biologically-active surface area and will not clog due to biomass growth or particulate accumulation. The media bed is self-cleaning, and never needs to be replaced, and being a single-vessel system that can be sited close to the emission source, minimizing long duct runs, the MultiPhase has a small, manageable footprint, the company adds.
