Technical Explanation: Conventional Biofilters Compared to Our Unique Biofilter system

The Worldwide Unique Hartmann Biofilter system: Technical Superiority Over Conventional Biofilter Systems

At PureAir BioTech Inc., we set new standards in biological exhaust air purification ?with our unique biofilter system. Its worldwide unique, patented design overcomes the typical weaknesses of conventional solutions and offers a powerful and cost-effective alternative. Below, we explain why our system is considered a pioneering solution and how it surpasses conventional filters.

Challenges with Conventional Biofilter Systems?

Conventional biofilter systems typically use substrates like peat, brushwood, or shredded root wood, which provide microorganisms with an environment to break down pollutants from exhaust air. However, these systems present several technical challenges:

?

1. Uneven Airflow and Moisture Distribution

Conventional biofilters often utilize plastic honeycomb structures between the pressure chamber and the bioactive layer. While these systems are designed to evenly distribute airflow, they tend to clog over time, leading to blockages and uneven airflow. This inefficiency necessitates regular maintenance and replacement of the entire bioactive layer's substrate.

?

2. Moisture Distribution Problems

Moisture in conventional biofilters is often regulated through exhaust air scrubbers. This method frequently results in uneven moisture distribution in the bioactive layer, leading to density differences and "breakthroughs" in the filter. Air tends to take the path of least resistance, leaving entire filter sections unused and prone to composting. This situation requires regular material replacements and reduces overall efficiency.

?

3. Drawbacks of Exhaust Air Scrubbers?

Exhaust air scrubbers used in many conventional biofilter systems for humidifying and cleaning exhaust air present several drawbacks:

• Increased Maintenance Requirements: These systems require regular maintenance and cleaning to maintain hygienic standards.
• Complex Handling: Operating these systems necessitates trained personnel to adhere to hygiene requirements for water-bearing systems.
• Risk Management: Handling water-bearing systems can pose health risks that need constant monitoring.

?

Impact on Customers of Conventional Systems?

For customers of conventional biofilter systems, this translates into increased maintenance and operational demands. The necessity for regular maintenance and microbiological testing can elevate operational costs and introduce legal risks. High hygiene and maintenance requirements can consume both time and financial resources, thereby compromising efficiency.

?

Conclusion?

The challenges associated with using exhaust air scrubbers pose a significant burden for operators of conventional biofilter systems. By eliminating the need for exhaust air scrubbers, as implemented in the Hartmann Biofilter, operators can avoid these difficulties and opt for a sustainable, cost-effective solution for exhaust air purification that maximizes efficiency.

4. Compaction from the Weight of the Filter Substrate

Conventional biofilters often contain bioactive layers exceeding one meter in height, which become compacted under their own weight. This impairs airflow and increases the risk of blockages, leading to faster material decomposition and composting.

Our unique biofilter system: A Technical Innovation in Detail

Our unique biofilter system addresses these issues through a patented, multilayer structure that provides a reliable and economical alternative to conventional systems.

?

1. Continuous and Uniform Airflow Without Clogging

Our unique biofilter system completely eliminates plastic honeycomb structures, which pose a clogging risk. Instead, we utilize specially enriched wood chips that serve as the bioactive layer, offering a consistently permeable filter surface. Our innovative design ensures that exhaust air flows evenly through the filter. The absence of plastic honeycombs, combined with a clever layer construction, enables stable operation without regular substrate changes—a key advantage in terms of efficiency and cost-effectiveness.

2. Optimal Moisture Distribution Without Exhaust Air Scrubbers

Instead of an exhaust air scrubber, the Hartmann Biofilter employs a spraying system that precisely introduces moisture into the bio-bed. Each bioactive layer has its own water circulation system, equipped with spray nozzles distributed per square meter. Additionally, each layer is equipped with moisture sensors that monitor humidity levels, ensuring that the bioactive layer remains optimally moist. The control unit continuously regulates moisture, providing uniform hydration to the bio-bed and minimizing the risk of clumping and breakthroughs. This even moisture distribution creates an optimal environment for microorganisms and effectively prevents composting and material decomposition.

?

3. A Patented Design to Prevent Compaction and Clogging

The design of the Hartmann Biofilter utilizes a unique, patented layering system that prevents compaction from the weight of the bioactive layer and ensures even aeration. The filter consists of:

?

• First Pressure Chamber: It evenly distributes air pressure across the entire filter area.
• Special Understructure: This design supports the bioactive layer and prevents compaction from its own weight.
• First Bioactive Layer: This layer serves as the primary surface for microorganisms and pollutant degradation.
• Second Pressure Chamber and Understructure: These ensure optimal air pressure distribution across the filter surface.
• Second Bioactive Layer: This additional layer increases the biological filter capacity and provides redundant efficiency.

?

Through this multilayer design with alternating pressure chambers and support structures, compaction and clogging are reliably prevented, ensuring that the filter remains permeable and functional throughout its operational life.

Sustainability and Long-Term Operating Costs: Focus on Economic Efficiency?

Our unique biofilter system is not only an environmentally friendly solution but also a cost-efficient one. Unlike conventional systems that often require frequent maintenance and renewal, our system remains powerful and ready for use over the long term due to its intelligent design. This significantly reduces operating costs, as regular maintenance and material changes are not necessary.
