Air Scrubber

SHARE
Drying digestate, sewage sludge, and animal manure releases gases that impact the surrounding atmosphere. This is true of biogas plants and farms, and it includes upstream and downstream operations. In Germany, the Federal Immission Control Act forms part of the country’s Technical Instructions on Air Quality Control (known as ‘TA Luft’). This act prescribes precise specifications for the levels of toxic gases, such as nitrogen compounds, that are permissible in emissions.

A new TA Luft has been in force since 2021, enforcing stricter immission and emission requirements. The new version implements testing of the surrounding area to show the extent of the impact of exhaust gases. In addition, the emission thresholds for many substances were dramatically reduced. If any exhaust gases exceed these thresholds, the emissions contained must be reduced using an appropriate method such as a flue gas cleaning system.
Flue gas cleaning systems, also known as air scrubbers or multi-stage exhaust air cleaners, deliver an efficient and reliable reduction in certain components of exhaust air like ammonia and/or hydrogen sulfide. NEWeco-tec is your one-stop shop for everything from consulting and tailored system design to installation, commissioning and system maintenance. Our NEWair-scrubber is the ideal solution for clean air.

This flue gas cleaning system facilitates a modular structure that can be adapted to the on-site situation and authorization requirements. A combination of physical, chemical and biological cleaning processes provides a reduction in exhaust air content of ammonia, hydrogen sulfide, particulates and odors to comply with the law. Depending on the legal requirements for system approval, NEWeco-tec will design and build a one, two or three-step flue gas cleaning system.
