  • Biofiltration: An Innovative Technology for The Future

    Biofiltration refers to the biological transformation or treatment of contaminants present in the gas phase, usually air. The fact that air contaminants can be biodegraded by active bacteria has been known for quite some time. However, it is only in the last 10 years, that biofiltration has begun to emerge as an economically viable treatment process. Initially, biofiltration involved the use of ...

  • Effects of Operational Conditions on the Performance of Triethylamine Biofiltration

    ABSTRACT Nitrogen compounds such as triethylamine are odorants generally found in chemical plants and foundries in which cold-box cores are made. In this study, the efficiency of biofiltration of triethylamine (TEA) vapor was evaluated. Experiments were conducted in two 6-L biofilters arranged in three stages and packed with inoculated compost - wood chips (40:60v/v) as the filter medium. The ...

  • 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 ...


  • 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 ...


  • Biological Removal of Ammonia from Contaminated Air Streams Using Biofiltration System

    ABSTRACT Ammonia is a colorless, toxic, reactive and corrosive gas with a sharp odor. It is irritating to the skin, eyes, nose, throat, and lungs. Ammonia gas occurs in the environment naturally and is emitted by many industries and, therefore, its control is essential. Biofiltration is a new emerging technology that is being used as a control procedure. This study evaluates the use of a ...

  • Biofiltration systems for the treatment of waste gas from industrial plants

    Bord na Móna Environmental Ltd have considerable experience in the field of biological air filtration (600 installations). Initially, the majority of installations were on Municipal and Industrial Wastewater applications. This was quickly followed by Municipal Solid Waste, an application Bord na Móna jointly developed with its Italian partners Air Clean srl. Since 2000, Bord na Móna have ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • Selection of Bioreactor Media for Odor Control

    The support media is one of the most critical elements of a biofiltration system. In this chapter, biofilters and biotrickling filters will be referred to as “biofilter”, and this distinction will be discussed later in this chapter. The support media’s main function is to provide contact between the gas-phase contaminants and active microbial cultures either immobilized within and/or attached as ...

  • Nature’s Own - Biofiltration Process Offers Promise of (near) Energy-free Pollution Abatement

    A filter could be described as any substance through which liquid is passed to remove suspended impurities. Although a “biofilter” is actually not a filter, “biofiltration” is on the threshold of finding a market as a compliance solution for air pollution regulations after a number of false starts. Biofilters have long been used as a means for reducing objectionable odors in Germany, the ...

  • An odor predictive model for Rendering applications

    Abstract The rendering process consists of crushing and heating animal remains to produce by-products. The U.S. produces approximately 30 billion pounds of inedible animal by-products annually, exporting a market value of US$ 1.5 billion. Benefits of the rendering process include reducing total waste material, and helping the livestock industry stay competitive over vegetable protein ...

  • Case study - Meat processing odor control

    Overview For its first two years of production, a food manufacturer based in South Wales, England, focused its production on potatoes. Neighborhood residents voiced no complaints about odors during this time period. However, as new production lines (including barbequed meats and curried chicken) were added, the complaints began, and it became clear that odor abatement equipment was needed ...

  • Biofilter array ends odor complaints from sewage transfer line - Case Study

    Management at Jefferson County (AL) Environmental Services reports it has solved a long-running odor problem by tapping a 30,000 din-capacity biotilter array into a 14 mgd average, 55 mgd maximum sewage, transfer line. The 6-unit BASYS array was manufactured by Biorem Technologies Inc. of Guclph, Ontario. The array handles hydrogen sulfide at average concentration of 5 ppm, and maximum of 25 ...
