Bioscrubbers Odor Control

BASIIA ENGINEERING offers advanced bioscrubber systems that provide reliable, automated, and sustainable solutions for treating odorous air emissions. Ideal for industries requiring continuous and high-capacity odor control, bioscrubbers combine chemical absorption with biological degradation in a closed-loop system.

A bioscrubber is a two-stage odor control unit that first absorbs odorous gases in a liquid phase (scrubbing liquid) and then biologically treats them in a bioreactor. The system uses specialized microorganisms to break down contaminants like hydrogen sulfide (H₂S), ammonia (NH₃), and VOCs into harmless compounds—without generating hazardous waste.

Bioscrubbers are highly effective in odor-intensive environments, such as:

• Municipal wastewater treatment plants
• Sludge handling and dewatering facilities
• Food and beverage processing plants
• Chemical and pharmaceutical manufacturing
• Organic waste transfer stations
• Rendering and composting facilities

1. Air Intake: Contaminated air enters the absorption column, where it contacts a recirculating scrubber solution.
2. Absorption Phase: Odorous compounds dissolve into the liquid medium.
3. Biological Reactor: The absorbed pollutants are biologically degraded by aerobic microbes in the bioreactor.
4. Clean Air Outlet: The treated air exits the system with >95% odor removal efficiency.

1. Pre-treatment: Air is humidified to create optimal conditions for microbial activity.
2. Biological bed: The air is passed through a structured media bed where odor molecules are absorbed and degraded by biofilms.
3. Clean air outlet: The treated air exits with dramatically reduced odor levels—often over 95% removal efficiency.
