As global environmental awareness continues to rise, air pollution control has become a pressing concern. Among various emission sources, odor pollution from wastewater, organic waste, and industrial processing remains a major challenge. One of the most effective and eco-friendly solutions to tackle this is the biofilter deodorization system.

At Chaori Purification, we provide advanced biological deodorization equipment that leverages microbial metabolism to neutralize odorous gases, offering a sustainable alternative to chemical or thermal treatment methods.

Working Principle of a Biofilter Deodorization System

The core of a biofiltration system lies in using biological media as a carrier for specialized microorganisms. Under suitable temperature and humidity conditions, these microbes utilize organic and inorganic substances in the waste gas as a nutrient source. Through natural metabolic processes, odorous compounds are broken down into harmless byproducts like carbon dioxide (CO?) and water (H?O).

The Three-Stage Process:

1.Absorption Phase

Odorous pollutants in the waste gas come into contact with a moist biofilm on the filter media and dissolve rapidly into the water layer.

2.Diffusion Phase

Once dissolved, these compounds diffuse into the biological membrane where pollutant concentration is lower. This gradient drives efficient mass transfer into microbial zones.

3.Degradation Phase

Microorganisms metabolize the absorbed compounds, converting them into non-toxic and environmentally benign substances via respiration or fermentation, depending on microbial type and process design.

Key Features of Chaori's Biofilter Deodorization Systems

? Eco-Friendly Biological Treatment

Utilizes natural microbial action with no secondary pollution, unlike chemical scrubbers.

? Multi-Compound Treatment Capability

Capable of handling complex waste gases containing multiple odor-causing substances, including ammonia, hydrogen sulfide, and volatile organic compounds (VOCs).

? High Efficiency & Fast Response

Efficient odor removal in short contact time, with typical removal rates exceeding 90% under proper operating conditions.

Typical Application Scenarios

Chaori's biofilter deodorization systems are widely used across multiple industries and urban infrastructures, including:

• Municipal wastewater treatment plants – removal of hydrogen sulfide and ammonia
• Solid waste transfer stations and landfills – control of organic decomposition odors
• Feed and livestock facilities – removal of ammonia and fermentation gases
• Food and beverage processing plants – treatment of flavoring agents and fermentation residues
• Biopharmaceutical and fermentation industries – handling of VOC-laden exhaust

Our modular biofilter units can be customized in size and configuration to suit indoor or outdoor installations and integrate seamlessly into existing exhaust pipelines.
