Odour Handling

Bio Filter

In the rendering industry, a biofilter is used to treat odorous and potentially harmful emissions. Rendering involves processing animal by-products, such as fat, bone, and protein, to produce various products like animal feed, fats, and oils.

During the rendering process, strong odors can be released along with volatile organic compounds (VOCs). A biofilter is designed to capture and treat these emissions by using natural microorganisms to break down the odorous compounds.

Biofilters consist of a bed of organic material, such as compost or wood chips, which acts as a support medium for microorganisms. The exhaust air from the rendering process is passed through the biofilter, allowing the microorganisms to consume and metabolize the odorous compounds. The filtered air is then released into the atmosphere with significantly reduced odor levels.

The effectiveness of a biofilter depends on factors such as temperature, humidity, nutrient availability, and contact time between the air and the organic material. Regular monitoring and maintenance of the biofilter are necessary to ensure its optimal performance.

Biofilters are considered an environmentally friendly and cost-effective solution for odor control in the rendering industry, as they utilize natural processes to treat emissions.
