Biological/Aeration Tanks
Aeration tanks are a critical stage in the treatment of urban and industrial wastewater. These structures enhance the biological purification process by injecting air or oxygen into pre-treated effluents.
- High corrosion resistance in highly oxygenated environments
- Fast tank assembly: approximately one week for a 500 m³ unit
- Large-diameter structures (up to 50 m) or tall structures (up to 20 m)
- Highly adaptable to various treatment solutions
- Numerous reference installations
APRO Industrie Aeration/Biological Tanks
APRO Industrie designs and installs aeration and biological tanks ranging from 5 to 10,000 m³ for industrial and municipal wastewater treatment plants. Our expertise ensures tailor-made solutions perfectly adapted to your specific requirements.
Role of Aeration tanks in Effluent Treatment
Aeration tanks receive pre-treated effluents to continue biological treatment. The injection of air or oxygen enhances oxidation processes, requiring materials with high corrosion resistance.
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 durability in highly oxygenated environments. APRO Industrie’s modular metal solutions are versatile and support multiple treatment methods:
-
Fluidized beds (MBBR)
-
Biofilm beds
-
Ultrafiltration blocks (BRM)
Available Equipment for Optimal Performance
Aeration tanks can be equipped with all standard accessories for this type of installation, including hydro-ejectors, fine-bubble aeration systems, scraper bridges, surface aerators, and biomass supports, allowing optimal adaptation to your operational needs.
