Bolted Biological Treatment / Aeration Tanks
Aeration tanks are a key component of urban and industrial wastewater treatment systems. They enhance the biological treatment process by injecting air or oxygen into pre-treated effluents.
- High corrosion resistance in highly oxygenated environments
- Fast installation: approximately one week for a 500 m³ tank
- Large-diameter structures (up to 50 m) or tall structures (up to 20 m)
- Compatible with a wide range of wastewater treatment processes
- Numerous reference installations
APRO Industrie Bolted Biological Treatment and Aeration Tanks
APRO Industrie designs, manufactures and installs aeration and biological treatment tanks ranging from 5 to 10,000 m³ for industrial and municipal wastewater treatment plants. Our expertise enables us to deliver tailored solutions designed to meet your specific treatment requirements.
The Role of Aeration tanks in Effluent Treatment
Aeration tanks receive pre-treated wastewater and support the biological treatment process by promoting the growth and activity of microorganisms. The continuous injection of air or oxygen promotes biological oxidation and requires materials capable of withstanding highly corrosive operating conditions.
Technical Characteristics of Our Biological and Aeration Tanks
Our tanks are typically constructed from glass-fused-to-steel with mastic sealing or epoxy-coated steel with mastic or elastomer sealing. These materials provide excellent resistance in highly oxygenated environments. APRO Industrie’s modular tank solutions can be adapted to a wide range of biological treatment processes, including:
-
Moving Bed Biofilm Reactors (MBBR)
-
Trickling filters
-
Membrane Bioreactors (MBR)
Available Equipment for Optimal Performance
Aeration tanks can be equipped with a full range of process equipment, including: including hydro-ejectors, fine-bubble aeration systems, scraper bridges, surface aerators, and biomass supports, ensuring optimal treatment efficiency and operational performance.
