Bio Scrubber System for H₂S Removal in Industrial Facilities

Bio Scrubber System for H₂S Removal in Industrial Facilities
Hydrogen sulfide gas (H₂S) is commonly found in various industrial processes, especially in industries related to the decomposition of waste or organic matter—such as wastewater treatment plants, sugar factories, food processing plants, refineries, and the petrochemical industry. H₂S does not only emit a strong rotten egg odor, but it also poses serious health risks to workers and causes rapid corrosion of equipment within the system.

One of the most effective and environmentally friendly treatment methods is the Bio Scrubber System, which has become an increasingly popular solution for H₂S removal.

What is a Bio Scrubber System?
A bio scrubber is an air treatment system that uses microorganisms to biologically degrade air pollutants such as H₂S without the use of chemicals. The system consists of a tank filled with bio packing media, where microorganisms live that can efficiently break down toxic gases. As the contaminated air passes through, the microorganisms perform biochemical reactions to convert harmful gases into harmless substances such as water, sulfate (S), or sulfur compounds like SO₄.

Working Principle of the Bio Scrubber System

1. Air Intake: H₂S gas from production processes is drawn into the bio scrubber tank.
2. Condition Adjustment: The system maintains optimal conditions for microbial growth.
3. Contact with Bio Media: The scrubber tank contains bio packing media colonized by specific strains of microorganisms that target H₂S.
4. Biodegradation Process: The microbes biologically degrade the H₂S gas into non-toxic substances.

Advantages of the Bio Scrubber System

• No chemicals needed — Safe for workers and environment.
• Lower operating costs compared to chemical scrubber systems.
• Suitable for treating air with high concentrations of H₂S.
• High H₂S removal efficiency — Can be custom-designed to meet specific performance requirements (e.g., reduce H₂S from 200 ppm to <10 ppm).
• No advanced technology required — easy to operate and maintain.

Design and Operational Considerations for using the Bio Scrubber System

• The system requires more installation space than chemical scrubbers due to the biological treatment process, resulting in a higher initial investment.
• Not suitable for systems with highly fluctuating airflow rates or H₂S concentrations.

Industries Best Suited for Bio Scrubbers
Bio scrubber system is ideal for industries such as sugar factories, starch plants, feed mill production, liquor and beer factories, or biogas plants. These industries generate high levels of organic waste, which leads to the emission of strong odors—especially H₂S gas—at concentrations higher than in many other industries. Therefore, a bio scrubber system is a cost-effective and efficient solution for odor control in these applications.
