Integrated Biotrickling Filter and Biofilter Systems

Envirogen integrated biotrickling filter and biofilter systems provide some of the most technically advanced solutions for mid-range air flow odor and volatile organic compounds (VOC) control applications. Integrated biotrickling/biofilter systems consistently remove hydrogen sulfide (H₂S) to above 99% levels and can remove other compounds in the over 95% range.

The result of 25 years of research, design and operating experience, these systems combine the high performance of a biotrickling filter design in removing H₂S with the VOC; and reduced sulfur compound efficiencies of a biofilter. Both are housed in a single, prefabricated fiberglass system that offers ease of installation and small system footprint.

Key advantage – multi-zone treatment for odor and VOC Control

Envirogen biotrickling filter and biofilter technology systems can be configured to offer multiple zones of treatment – for efficient and cost-effective management of complex air streams. Biofilter trickling design is integrated with biofilter system configuration that can feature up to three different ‘ecozones’ – employing different media, pH, humidity and flow design.

Our advanced odor and VOC control system design allows the growth of micro-organisms that target specific contaminants in the air stream more effectively and efficiently than a single media system can allow. Furthermore, it also allows for optimisation of media life and leads to lower long-term operating costs for both energy and media.
