 Tri-Mer Corporation announces
a major advance in VOC control technology.
It is a more practical alternative to regenerative
thermal oxidizers or traditional biofilters.
The MulitPhase combines both a biofilter
and bioscrubber for total VOC control.
There is now a cost-effective, reliable,
and proven technology for controlling
formaldehyde emissions, also methanol,
turpenes, and other VOC emission types
generated by board plants, as well as the
manufacturing of fiberglass, adhesives,
paints, resins and other VOC sources. Major Advantages of the MultiPhase Bio-filter:
- MultiPhase Biofilters are engineered to handle higher gas temperatures
and high particulate loading in the inlet gas.
- Compact footprint; single-vessel design for total VOC control
- Uses ceramic media instead of plastic or compost
- Tri-Mer MultiPhase Biofilters handle tars, waxes, heavy VOC compounds
- Meet MACT standard for VOC control, including formaldehyde, methanol, turpenes
- MultiPhase Biofilters will not clog due to biomass growth,
so no replacement of media is required, even after 10 years of continuous
operation; automatically self-cleaning
- Minimizes water consumption through extensive water recycling
- MultiPhase Biofilters have very low system pressure drop and operating costs.
- Minimal waste generation; creates no NOx compounds
- MultiPhase Biofilters have a proven track record with large and
small full-scale operating installations in the US.
This MultiPhase Biofilter System for VOC control combines the best of biofilter and bioscrubber
technology. It treats high inlet concentrations of VOC in a tank configuration with a manageable
footprint. Unlike the large, in-bed biofilter approach of the past, this proven new technology can
be sited close to the emission source, minimizing long duct runs. MultiPhase Biofilters can also
accept much hotter sources, dryers for example. This unique Biofilter system is much less expensive to install and operate over time than older
combustion approaches used for VOC emission control. It provides high removal rates on high
particulate concentrations and heavy loadings of biological treatment products, without clogging the
biofilter media beds. By contrast, even small concentrations of particulate in the gas stream pose
serious challenges for regenerative thermal oxidizers, specifically, bed fouling and degradation.
The presence of particulate can also cause fires in regenerative thermal oxidizers. Often, the cause
of the fire is media bed plugging caused by the accumulation of coarse particles from mechanical
sources. Fine particles, in the form of condensable organic compounds, also cause problems for
regenerative thermal oxidizers. If they are chemically inert, they can plug the heat exchange media.
Chemically reactive fine particulate are also prone to plug the media of regenerative thermal oxidizers –
and they create another hazard as well, in that they can attack the heat exchange media in the
oxidizer. Tri-Mer Biofilters avoid these difficulties.
Tri-Mer Biofilters uses permanent media – no replacement of media or packing is necessary.
Initial costs are generally comparable to older biological approaches, and the MultiPhase system
is highly reliable, with lower maintenance and operating costs, plus providing superior performance.
MultiPhase Biofilters have a fraction of the life-cycle cost of regenerative thermal oxidizers,
given the large perpetual operating expense in natural gas. The new MultiPhase BioSystem for VOC control generates minimal waste and does not create
NOx by-products because there is no combustion. NOx regulation is increasing, and poses a
problem for regenerative thermal oxidizers. It also produces much lower CO2 over the life-cycle because the biofilter media does not degrade,
unlike old-style biofilter media. The Tri-Mer system addresses a broad spectrum of VOC control challenges. Alcohols,
including methanol and other high vapor pressure VOCs, are simultaneously treated along
with more challenging VOC control issues, such as turpenes and pinenes. Formaldehyde
emissions, perhaps the most problematical from a regulatory perspective, are readily removed.
The system is highly flexible, with options for treatment of numerous volatile organic compounds
such as styrene, xylenes, PAHs, ethanol, glycols, solvents, sulfur compounds and others.
The underlying design philosophy focuses on MACT compliance.
Time is critical in complying with air emissions regulations found in the VOC MACT standards.
The Tri-Mer MultiPhase BioSystem is a cost effective, reliable and proven solution.
When considering a system for VOC emission control, don't let the old approach
blind your evaluation and lock you in to high energy costs.

Tri-Mer’s MultiPhase Biofilter meets the regulatory standards
applicable to manufacturers of engineered lumber, LVL, PSL, LSL, OSL,
and other MACT standards for VOC control. A Growing List of Companies from Diverse Industries
Have Chosen the MultiPhase Biofilter Over
Regenerative Thermal Oxidizers 
The U.S. Court of Appeals for the District of Columbia has invalidated the
“low risk” subcategory provisions of U.S. EPA MACT emissions rules for
plywood and other engineered wood product facilities. The ruling means
that sources previously exempted from VOC control limits will now have
to install VOC control technology such as regenerative thermal oxidizers,
biofilters or a MultiPhase Biofilter system.
