2020/4/3Thus this book provides tools for solving air pollution issues in a sustainable manner. These issues can be solved at different levels (e.g., end-of-pipe gaseous streams, indoor/outdoor air, closed environments), which can be approached by the different biotechniques presented in the book, from classical biofiltration techniques (part 1) to phytotreatment and microalgae-based techniques
Biofiltration is a biological air pollution control technology for volatile organic compounds (VOCs). This paper summarizes the fundamentals, design and operation, and application of the process. Biofiltration has been demonstrated to be an effective technology for VOCs from many industries.

White Paper: Biofiltration: An Innovative Technology For The Future. By Dr. Rakesh Govind, Professor of Chemical Engineering, University of Cincinnati. 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
Biofiltration is a relatively new technology for control of air pollutants, in which the air contaminants from off-gas streams are biologically removed in a solid biological reactor. While it is a well established air pollution control technology in European countries, biofiltration as an air pollution control technology has received little attention and application in the United States.
Reduction of hazardous air pollutant emissions using biofiltration
Significant reduction in the emissions of organic hazardous air pollutants (HAP) associated with surface coating operations was demonstrated through the application of an innovative and low cost biofiltration system. A laboratory‐scale biofilter employing yard waste
Mass transfer and degradation dynamics analysis of biofiltration
Ultraviolet photodegradation (UV) was utilized as a pretreatment to enhance the biofiltration process (BF and BTF) for the removal of hydrophobic α-pinene. Based on the experimental data, the mass transfer behavior and microbial activity were analyzed by the

2019/6/6Biofiltration improves IAQ efficiency, research shows. June 6, 2019 - The traditional means of maintaining indoor air quality (IAQ) is to displace the 'dirty' air inside a building with new, 'fresh' air from outside. Since outdoor air quality is generally very good across North America, this method has proven effective at both (a
Multiplexed Biofiltration of Volatile Organic Compounds
2016/8/26DESCRIPTION: Innovative biofiltration capabilities to treat a range of VOCs in a variety of closed environments represent a critical DoD need. Effective management of air quality is essential for the optimal performance and health of those who operate in closed environments, such as underwater vehicles, air and spacecraft, and factories, for long periods of time.
