    Turnkey project: biofilter and humidifier

    Product: Biofilter Sector: Waste Management

    Air Extraction and Biofilter for Waste Recycling Logistics Center

    At AEC Systems, we have successfully installed a turnkey air purification system at a Recycling and Logistics Center in North Rhine-Westphalia, Germany. This system, featuring a covered biofilter with a humidifier, offers an efficient solution for odour removal and air purification. Delivered as a turnkey project, the system was completed in just six months, from initial design to full commissioning.

    Odour Removal Techniques
    • System design: We developed an efficient network of air ducts to extract air from two large waste-sorting halls. The contaminated air is channelled through these ducts to a humidifier.
    • Covered biofilter: The purified air is then processed through a covered biofilter housed in a closed concrete structure, topped with a durable tarpaulin cover.
    Key benefits of the covered biofilter
    1. Enhanced performance: The cover ensures controlled airflow, promoting consistent and even humidification of the filter material. This improves the efficiency of microorganisms, boosting the removal rates of odours and ammonia.
    2. Protection against weather: The biofilter cover shields the filter mass from sunlight, rain, snow, and extreme temperatures, extending the material's lifespan and ensuring stable operation.
    3. Improved airflow: Controlled airflow helps capture and remove dust and debris, creating a cleaner and healthier working environment.

    Biofilter Media: The heart of efficient air purification

    The unique properties of biofilter media stimulate microbial activity, ensuring optimal air purification. Key advantages include:

    • Large specific surface area: Its complex structure provides ample surface area for microorganisms to thrive, enhancing the breakdown of airborne contaminants.
    • Low pressure drop: The open structure minimizes airflow resistance, reducing system energy consumption.
    • High water retention capacity: The media retains moisture effectively, creating the ideal environment for microorganisms to function efficiently.
    • Stable pH levels: Naturally maintains a neutral to slightly acidic pH, beneficial for microbial activity.
    • Long lifespan: With proper maintenance, biofilter media can last 3 to 5 years, maintaining its structure even in humid conditions.
    • Sustainability: Biofilter media is biodegradable and environmentally friendly, supporting a greener and more sustainable air purification process.
    Biofilter technology: A sustainable solution for clean air

    Biofilters are a proven and eco-friendly method for odour removal and the treatment of airflows with low or undefined concentrations of contaminants. Through integrated biological regeneration, microorganisms in the biofilter naturally break down harmful substances.

    This environmentally friendly technology operates under optimal conditions:

    • Ambient temperature: No additional energy required for heating.
    • Neutral pH levels: Ideal balance for microbial activity.
    • Normal pressure: Simplified installation without complex pressure systems.
    Applications of biofilter technology by AEC Systems

    We have successfully implemented biofilter solutions in various industries:

    • Wastewater treatment: Managing airflows containing hydrogen sulphide and other odorous compounds.
    • Composting: Addressing odour issues during organic material processing.
    • Waste management: Eliminating odours in waste storage and processing facilities.
    • Food production: Removing organic odours and volatile compounds.

    By choosing our biofilter technology, you opt for a cost-effective and environmentally responsible approach to air purification.

    Together, we can create a cleaner and healthier future 🌍✨
