The AirShield is designed to treat toxic and odorous gases at wastewater treatment plants and other industrial facilities. Target gases include sulfur-containing compounds such as H₂S and dimethyl sulfide (DMS), amines, aldehydes, terpenes, aromatics and other odors and (very) volatile organic compounds (VOCs).
A stand-alone unit can effectively treat peak concentrations of up to several hundreds parts per million (e.g. 750 ppm for H₂S). We offer site assessments to confirm that the AirShield is suitable for your specific airflow.
The AirShield will be configured to suit your site-specific requirements, such as the maximum residual emission and/or required removal rate. In field operations at wastewater treatment plants and pumping stations the AirShield shows removal rates of >99% with residual odor concentration of <75 ouₑ/m³. We offer assessments to determine the expected performance on your airflow.
The AirShield is built to perform reliably across seasons and in outdoor conditions. It’s designed for rapidly varying and condensing environments such as commonly present at wastewater facilities. Typical operating temperatures are -10 to 40 ℃. Appropriate ATEX-aligned configuration can be engineered based on your zone classification and project requirements.
The AirShield has built-in sensor slots for (remote) output and status monitoring. We provide data-enabled services such as emission monitoring and reporting, performance optimization and predictive maintenance. If desired, we offer onsite pilots and demonstrations to validate performance under real operating conditions.
The AirShield cleans air based on our patent pending gas-phase advanced oxidation process (GPAO). The goal of our GPAO process is to neutralize toxic and odorous gases, turn these neutralized gases into particles and then remove the particles from the air. This sequence is completed because particles are easier (and thus more cost effective) to treat than gases.
The AirShield uses sensor-driven power control to automatically adjust treatment intensity to changing inlet conditions. This allows rapid response to peak loads and fast fluctuations that are typical for pumping stations and wastewater treatment plants, reducing the risk of “breakthrough” emissions. The control strategy is configured per site, based on pollutant mix, variability, and operational priorities (energy vs. margin).
The TCO depends primarily on treated airflow (m³/h), pollutant load and variability (e.g., H₂S/DMS peaks), operating hours, and the required outlet target. Operating expenses are typically made up of electricity consumption (Wh/m³), planned maintenance and service, and consumables such as filters and sensors. During a site assessment we provide a TCO estimate for your location, including typical and peak energy use, expected maintenance intervals, and consumables, so you can compare CAPEX and OPEX against alternatives such as activated carbon, biofilters, or scrubbers.
Electricity use depends on airflow rate, inlet concentration, temperature and humidity. Typical ranges are 0.5 – 1.5 Wh/m³ for low concentration airflows at up to 5 Wh/m³ for high concentration airflows (incl. fan). The AirShield minimizes energy consumption by matching operating power to pollutant concentration based on sensor feedback. Using the specifics of your airflow we provide typical and peak energy consumption estimates.
No chemical dosing is required. The AirShield uses electricity and the water and oxygen naturally present in the air to generate reactive species in-situ for oxidation. Any residual reactive species are converted downstream using an integrated catalyst.
Typical requirements include an inlet duct, electrical connection, and sufficient access space for service. Depending on configuration and requirements, additional interfaces such as drainage/condensate handling or instrumentation signals may be required. Installation time depends on site constraints; many projects can be installed and commissioned in a day once the site is prepared.
The yearly maintenance is designed to be straightforward and can be performed by a trained operator, a local service partner, or our team, depending on your preferences. Tasks include inspection, checking sensors, and scheduled replacement of consumable components. We can provide service agreements and planned maintenance to ensure reliable performance. If desired the AirShield can be equipped with sensors for predictive maintenance.
The AirShield has built-in mechanisms to treat oxidation byproducts. The target gases that are converted to particles are treated in particle filters that need to be replaced once a year. Any residual oxidants are converted in an integrated catalyst. The catalyst’s lifetime depends on the specifics of the airflow. These replacements are the main source of secondary waste and are handled within standard industrial maintenance workflows.
