Biofiltration: a sustainable approach to reducing emissions

Written by Cindy Vargas | Oct 15, 2024 6:30:00 AM

In the context of increasing global concern for the environment, reducing emissions has become a top priority, and biofilters can help companies achieve important sustainability goals.

Indeed, more and more companies are committed to complying with environmental regulations and adopting innovative technologies to minimize their ecological impact by reducing emissions. It is in this scenario that industrial biofilters represent a sustainable and effective solution for reducing emissions of gaseous pollutants.

How do industrial biofilters work?

Biofilters are purification systems that use the biological activity of microorganisms to treat polluted gas emissions. Their operation is based on a simple yet effective principle: the air to be treated is passed through a porous organic material, called a filter bed, which serves both as a physical support and, partially, as a nutrient source for the microorganisms. This bed can be made of natural materials such as bark, shredded wood, compost, or peat.

As the gas flow passes through the biofilter, pollutants such as Volatile Organic Compounds (VOCs) and odors come into contact with the microorganisms present in the filtering medium. These microorganisms, particularly aerobic ones that require oxygen to live, "digest" the pollutants, transforming them into carbon dioxide (CO₂), water, and biomass. This biological process not only eliminates harmful substances and reduces odors, but also produces non-hazardous by-products, such as water and CO₂, making the treatment both sustainable and environmentally friendly.

In summary, biofilters reduce polluted gas emissions by using natural processes, leveraging the metabolic capabilities of microorganisms to convert harmful compounds into non-odorous and harmless substances, thereby improving air quality in an ecological and sustainable way.

What are the main pollutants treated by biofilters?

Industrial biofilters are capable of treating a wide range of gaseous pollutants. The main ones include:

  • Volatile organic compounds (VOCs): result from industrial processes such as chemical and pharmaceutical manufacturing and can cause smog and respiratory problems.
  • Odors: foul-smelling emissions are common in industries such as waste treatment and agribusiness, and industrial biofilters offer an effective solution to abate odors.
  • Toxic gases: such as ammonia, which can be present in emissions from some agribusiness industries.

What are the environmental and operational benefits of industrial biofilters? 

One of the main advantages of biofilters is their environmental sustainability. Unlike other emission reduction technologies, biofilters use no chemicals and produce no toxic waste. In addition, they offer the following benefits:

  • Reduced environmental impact: by using biological processes, industrial biofilters help reduce greenhouse gas emissions.
  • Energy efficiency: compared to other technologies such as activated carbon filters or incinerators, they require less energy to operate, reducing operating costs.
  • Long life: with proper maintenance, they can operate effectively for many years, making them a cost-effective long-term solution.
