  • Biofilter Removal of VOCs and Toxics from Airborne Emissions

    Abstract Sewage treatment plants can emit significant quantities of volatile organic compounds (VOCs) and toxic air contaminants, but emission control by conventional methods has been difficult to achieve. The biofilter technology developed in a previous contract can satisfactorily control emissions from these plants and possibly from other sources of high-volume, low-concentration emissions ...


  • High VOC Loadings in Biofilters - Petroleum and Industrial Applications

    ABSTRACTMore cost effective alternate technologies are needed to meet the demands of existing and upcoming Federal air regulations. Bio-Reaction Industries, Inc. (BRI) has developed a patented, modular, high-rate, vapor-phase biofilter that has provided such a solution for a major oil company for the past four years. This compact system has adsorbed and digested high VOC surge concentrations ...


  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • Biofilter Applications in the Coatings Industry.

    Soaring energy costs and the high cost of ‘end-of-pipe’ pollution control equipment has caused companies and regulatory agencies to re-evaluate ‘unconventional’ means of achieving VOC and HAP emissions control. The coatings industry is an excellent candidate for alternative, unconventional controls, as VOC and HAP reductions have not been as strident as has been the case in many other industries. ...

  • Significant Improvements in Biofilter Performance for H2S and VOC Removal Using Biotrickling/Bioscrubber Technology in the Aeration Distribution Plenum System

    ABSTRACT Biofilters can handle the removal challenge of a diverse mix of complex odors and VOCs. However, there are significant limitations in handling levels of hydrogen sulfide (H2S) loadings above 10 ppm. High levels of H2S loading in biofilters will create an increase in the acidithiobacillus colony causing an overproduction of acid. This will destroy all other biodegrading ...

  • Report claims biofilters provide operating costs advantages

    As much as several million dollars over a 10-year period When determining the optimum HAP (hazardous air pollutant) and/or VOC (volatile organic compound) controls, it is imperative to assess all available options with respect to the existing and future operations at each mill. The correct choice for one application may not be best for all; and as operating conditions, raw materials, resins, ...


  • Results of Full-Scale Installation and Comparison of Biofilter Operation (PDF)

    ABSTRACTBio·Reaction Industries LLC. (BRI) has completed a two-phase project for the design, testing and installation of a biofiltration unit to degrade volatile organic compounds (VOCs) including benzene, toluene, xylenes, ethyl benzene, hexanes, MEK, MIBK, acetone and certain alcohols to reduce emissions from a paint manufacturing facility in Eugene, Oregon. The initial biofilter installed was ...


  • Biofiltration of hydrophobic VOCs pretreated with UV photolysis and photocatalysis

    The effects of pretreatments on the biofiltration of gas phase α-pinene, a poorly water soluble Volatile Organic Compound (VOC), was evaluated in a controlled and long-term experimental investigation. Ultraviolet (UV) photolysis and photocatalysis were used and compared as pretreatment techniques. A control experiment involving biofiltration alone allowed for the direct evaluation of the coupled ...

  • Biofiltration of VOCs for Paint Manufacturing and Coatings Applications

    Biofilters, long used in Europe for odour control because of low maintenance, energy and operating costs have had a difficult time penetrating the US. The energy crisis and the cry for sustainable technologies have created interest in pollution control devices that reduce emissions and are energy efficient. This paper will discuss technical performance, design factors and economics of a ...


  • Synthetic Media Biofilter Eliminates Hydrogen Sulphide and Other Reduced Sulphur Compound Odours

    Abstract Innovative synthetic biofilter media has revolutionized biofilter technology for removal of hydrogen sulphide (H:S) odours from several wastewater treatment facilities across North America. The major drawback of biofilter technology in the past was use of organic wood-based media, which had several problems including high-pressure drop, frequent media replacement, lack of ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

  • Biofiltration - A Disruptive Technology for Sustainable Air Pollution Control

    ABSTRACTAir Pollution Control has emerged over the past 40 years as a significant industrial sector helping industrial facilities reduce emissions to comply with environmental regulations, reduce costs, and improve their public image. A variety of technologies have been developed to meet the needs of both the industries and the regulatory agencies.  Engineered biofiltration is a sustainable ...


  • Clearing the air: the use of bio-oxidation for industrial air emissions control

    The wood products industry began rather ardous road to emissions control in the early 1990s with the first installation of a thermal oxidizer (an RTO) at a California MDF facility, for volatile organic compound (VOC) control. During the ensuing years, virtually every panel board facility has had to control emissions of VOCs, and up until the last few years, always with some sort of thermal ...


  • The next generation biological odour control systems

    Odour is usually caused by the presence of hydrogen sulphide, mercaptans (Organic sulphur components) and ammonia, but also multiple other VOC’s (volatile organic compounds) bringing numerous odour complaints at e.g. WWTP’s, pumping stations and composting plants. An odour control system therefore will have to treat not only hydrogen sulphide, but also other pollutants to reduce the total ...

  • Bio-oxidation control of air emissions from panel board production – A new direction

    Biofilters or bio-oxidation systems have been used for control of air emissions, primarily odors, since the 1960’s. Those early uses in the U.S. were largely relegated to odor control, primarily H2S, mercaptans and skatols, from wastewater treatment facilities. The Europeans were more aggressive in applying biofilter systems to various industrial air emissions, again primarily for odor control in ...


  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Air Emissions from the automobile manufacturing industry: a bio-oxidation pilot study of paint emissions control

    Bio•Reaction Industries (BRI) was contacted by Toyota to assess the abatement potential of an engineered bio-oxidation system (biofilter). The proposed intent of the pilot was to evaluate the effectiveness of biofiltration as available alternative to traditional VOC removal technology on an existing 3 stage wheel paint booth. A pilot unit consisting of a biotrickling filter and a separate ...
