PureAirFiltration System

SHARE

Our filter system is available in single-layer and double-layer versions, both designed for effective exhaust air treatment. The main difference is that in the double-layer variant, a second, independent filter system is installed above the first bioactive layer. Each filter layer is monitored and controlled separately. If necessary, each filter layer can be re-impregnated with special bacteria through the irrigation system. Our proprietary control system allows us to record all relevant data in the filter, including pressure, current and target humidity, temperature, and water consumption, and to regulate them automatically according to predefined parameters.

Depending on your preferences, we can offer the filters as containers, surface filters, or customized with a roof and chimney, ideal for exhaust air treatment applications. There are also virtually no limits to the positioning of the filter. From ground level to hall roofs or covered parking areas, we have already implemented a wide range of solutions.

Moisture control and  irrigation system

The following sectors are among our customers:

  • Sludge drying
  • Wastewater treatment plants
  • Waste treatment facilities
  • Automotive suppliers
  • Automotive manufacturers
  • Wood processing industry
  • Food processing industry
  • Agricultural enterprises
  • Manufacturing industrial sector

The moisture in the biofilter is continuously monitored and controlled in each bioactive layer, ensuring efficient exhaust air treatment. If the predefined parameters in a bioactive layer are exceeded, the control system automatically sends a signal to the corresponding solenoid valve, which then opens. The irrigation system moisturizes the bioactive layer until the predefined parameters are slightly exceeded again. This ensures that the Hartmann Biofilter consistently achieves the optimal moisture level in the bioactive layers. Consequently, a previously installed exhaust gas washer is no longer necessary for effective exhaust air treatment.

The irrigation system consists of numerous small nozzles embedded in the bioactive layer and supplied with water through microtubes. Since both the nozzles and microtubes are placed within the bioactive layer, the irrigation system remains active even at low temperatures and does not need to be shut down, providing continuous and reliable exhaust air treatment.

CO2 Reduction and the Carbon Footprint: Why Our Biofilter is the Ideal Solution

In a world increasingly aware of the urgent need to reduce greenhouse gases, minimizing the carbon footprint has become a central focus of discussions. The carbon footprint refers to the total amount of carbon emissions, both direct and indirect, caused by human activities. Every effort to reduce these emissions contributes to the global fight against climate change.

One of the key technologies for air purification in industrial processes is the use of filtration systems. These systems aim to remove harmful emissions, such as volatile organic compounds (VOCs), before they are released into the atmosphere. Choosing the right technology is crucial for the efficiency of pollutant reduction and minimizing the carbon footprint.

Biofilters: An Environmentally Friendly Alternative

Our biofilter offers an outstanding solution for exhaust air purification that is both ecologically and economically advantageous. Biofilters operate naturally by utilizing microorganisms to convert harmful substances into less harmful compounds. This technology has several advantages over conventional methods such as Regenerative Thermal Oxidation (RTO) and activated carbon filters.

Reduced Energy Consumption and CO2 Emissions**

Compared to Regenerative Thermal Oxidation (RTO), our biofilter significantly reduces energy consumption. RTO systems burn organic pollutants at high temperatures, which requires substantial amounts of energy and results in high CO2 emissions. In contrast, biofilters operate at ambient temperatures and use biological processes to eliminate pollutants, thereby minimizing energy requirements. This leads to a significant reduction in the carbon footprint.

Avoidance of Secondary Emissions**

While activated carbon filters provide efficient adsorption of pollutants, they require regular regeneration or replacement of the filter media. This process can also involve high energy consumption and additional CO2 emissions. Moreover, there is a risk that the adsorbed pollutants may be released during regeneration, leading to secondary emissions. Biofilters avoid this issue as they operate continuously without the need for regeneration.

Durability and Sustainability**

Our biofilter system offers a long-term solution with minimal maintenance requirements and high durability. Unlike activated carbon filters that need to be replaced regularly and RTO systems that experience significant wear and tear, biofilters require less intervention and produce less waste and emissions over time.

Additional Advantages of Our Biofilter Over Conventional Biofilters**

Another crucial advantage of our biofilter is that, unlike conventional biofilters, it does not compost. This means that the filter material does not need to be replaced, significantly reducing maintenance costs and increasing efficiency. Our system is patented and unique worldwide. This innovation and exclusivity have led leading companies in the automotive, food processing, and wood-based materials industries to successfully adopt our biofilter.

Cost-Efficiency**

Not only is our biofilter superior in environmental terms, but it is also economically advantageous. Operating costs are significantly lower due to its low energy consumption and minimal maintenance requirements. This makes the biofilter a sustainable and cost-effective solution for companies aiming to reduce their carbon footprint.

Conclusion

In today`s world, where the pressure on companies to adopt sustainable and environmentally friendly technologies is increasing, our biofilter presents an ideal solution. By utilizing natural processes for pollutant removal, the biofilter not only contributes to reducing the carbon footprint but also surpasses traditional methods such as Regenerative Thermal Oxidation (RTO) and activated carbon filters in terms of efficiency, sustainability, and cost-effectiveness. Additionally, our patented and globally unique system offers significant advantages over conventional biofilters, making it the preferred choice of leading companies across various industries. Choosing our biofilter is not only a decision for the environment but also a wise business investment.
