Biorem’s Biotrickling Filters are designed for demanding applications of high concentrations of H2S or other water soluble compounds. We offer a range of structures and random packed medias to suit the specifics of your particular application.Simple to operate, these systems are robust and effective for a variety of applications:


  • High H2S
  • Methanol, MEK, Acetates, Formaldehyde
  • Ammonia (NH3) removal
  • Wastewater Treatment Plants
    • Head Works
    • Grit Removal, Bar Screens
    • Pumping Stations


Complex odors associated with various municipal wastewater treatment processes can be difficult to treat.  That is why Biorem offers a robust and cost effective approach by combining our biotrickling filters and biofilter technologies.  The first stage consists of a customizable biotrickling filter that is used as a roughing scrubber to remove elevated hydrogen sulfide concentrations, allowing the second stage biofilter to concentrate on the more difficult organic sulfides and VOCs.

  • Headworks
  • Bar screens
  • Biosolids management
  • Grit removal
  • Pumping stations
  • Industrial applications for VOC removal

Biogas Solutions

Untreated, contaminants found in biogas can cause significant, costly and irreversible damage to downstream equipment, resulting in an increase in costs due to repair, replacement and downtime. Biorem offers a proven, cost effective line of biogas conditioning systems designed to protect your equipment from the damaging effects caused by H2S, siloxanes and VOCs typically found in sewage, digesters or landfill gas. With increased knowledge of the need for energy independence and for the development of sustainable energy sources, biogas emissions can be converted to a valuable source of alternate energy.

Biorem is the leader in developing high performance, permanent filter media products. Biosorbens®, was brought to market 10 years ago as the first permanent biofilter media in North America and with it, Biorem has achieved recognized leadership in biofilter installations.

Today, Biorem continues to develop and commercialize top performing, proprietary filter media to provide the treatment of an ever widening array of air emissions. Biorem has expanded its product offering to include two new filter medias: XLD and LWE, which have higher performance efficiency, are more light-weight than Biosorbens® and are demonstrating strong customer acceptance.

The medias are engineered to exacting specifications, ensuring predictable and consistent performance in every application. Specifically designed for maximum removal efficiencies of odorous compounds, Biorem’s medias are all backed by a performance warranty.

A top performing, engineered inorganic permanent biofilter media which delivers consistent performance over the life of the media. BIOSORBENS® is ideal for applications where total odor removal is required. It is guaranteed to perform and carries a 10 year warranty.

The uniform and homogenous nature of this non-biodegradable media ensures even water distribution and superior predictable performance. The fluid nature of this media allows for easy installation and assumes the shape of the container. This property minimizes un-wanted voids and allows for uniform media distribution throughout the vessel.

A high performance engineered biofiltration media specifically designed for biosolids applications where the removal of high odor, low H2S and reduced sulfur compounds are critical. Total odor removal efficiencies of up to 99% can be achieved in 30 seconds and greater than 95% in 20 seconds or less, allowing XLD to achieve higher total odor removal in less than half the time of conventional inorganic biofiltration  medias. XLD’s short retention times and lightweight design allows for small footprints and unique bed configurations to meet specific site requirements.
