AEC Biofilters
A biofilter is an eco-friendly and highly effective solution for controlling odours in various applications. It utilizes biologically active materials, known as biomass, to support odor-degrading microorganisms such as bacteria, fungi, and yeasts. These microorganisms naturally break down odour-causing compounds, making biofilters a sustainable alternative to chemical or mechanical odour control systems.
How does a biofilter work?
A biofilter consists of organic materials that serve as a habitat for beneficial microorganisms. The composition may include root wood, bark, peat, coconut fibers, compost, or a mixture of these elements. As air passes through the biofilter, the microorganisms absorb and degrade odour molecules, neutralizing unpleasant smells efficiently.
The key to a biofilter's success lies in its permeable structure. This allows air to flow through the filter, even when the system supplying the air stream is not operational. The filter bed must remain consistently moist to ensure the survival of the microorganisms. To achieve this, a humidifier or wet scrubber is usually placed before the biofilter.
Biofilter technology: A sustainable solution for clean air
Biofilters are a proven and eco-friendly method for odour removal and the treatment of airflows with low or undefined concentrations of contaminants. Through integrated biological regeneration, microorganisms in the biofilter naturally break down harmful substances.
This environmentally friendly technology operates under optimal conditions:
- Ambient temperature: No additional energy required for heating.
- Neutral pH levels: Ideal balance for microbial activity.
- Normal pressure: Simplified installation without complex pressure systems.
Applications of biofilter technology by AEC Systems
We have successfully implemented biofilter solutions in various industries:
- Wastewater treatment: Managing airflows containing hydrogen sulphide and other odorous compounds.
- Composting: Addressing odour issues during organic material processing.
- Waste management: Eliminating odours in waste storage and processing facilities.
- Food production: Removing organic odours and volatile compounds.
