Biofilters are innovative and sustainable solutions for effective odor removal in industrial and environmental applications. These advanced systems use biological processes to efficiently reduce odors and help improve air quality. Discover with us the advantages of biofilter technology for your needs in air purification and environmental protection!

Discover the highly efficient solution for odour removal: Activated carbon filters. This technology uses the unique adsorptive properties of activated carbon to remove unwanted odours from the air. Due to its large inner surface area, the activated carbon effectively attracts odour molecules and binds them safely without the use of chemicals. Ideal for a wide range of applications, from wastewater treatment to food production, our activated carbon filter system offers a reliable solution that meets the highest standards in air quality. Rely on proven technology for clean and fresh air in any environment – with our activated carbon filters, unpleasant odours are no longer a problem.

When it comes to exhaust air purification, compounds that are particularly harmful to the environment and health pose a major challenge and must be purified to very low clean gas values. Our counter-current scrubber offers a cost-effective and efficient solution here. Choose our innovative and reliable solutions for a clean environment and a healthy future.

Our cross-flow scrubber achieves optimum flexibility. By arranging several scrubbing stages one after the other, dust, acidic or alkaline components of your exhaust air are removed in just one system.

With horizontal scrubbers, the exhaust air flows horizontally through the packing bed and comes into contact with the scrubbing liquid in a “cross-flow”. This transfers the pollutants from the air into the scrubbing water. Depending on the application, a chemical-oxidative or biological mode of operation is possible. Since each scrubbing stage has its own, self-sufficient scrubbing water system, different environments can be set through which the exhaust air must flow. This ensures optimal and targeted removal of the most diverse pollutants in one system.

Discover the symbiosis of biofilter and counter-current scrubber in a state-of-the-art system! With a compact design and high specific surface area of the packing, we offer a solution that efficiently treats even high concentrations of pollutants such as H2S. Our technology is based on proven biological exhaust air purification, but with a decisive advantage: the sorption of pollutants takes place in a trickle bed instead of a conventional filter bed. This innovative design is similar to a packed-bed scrubber, but works with a significantly lower sprinkling density, which considerably increases efficiency and cost-effectiveness. Decide for quality and innovation – choose our system!

More and more dusty emissions from humid processes are ending up in exhaust air streams that need to be treated before being released into the atmosphere. This is not only due to the particulate emissions themselves, but also to the odours they contain. The adhesion of strong-smelling compounds to particles in humid and often hot exhaust air leads to an increased odour perception in the environment.

Tholander has developed a compact system specifically for this exhaust air problem, based on a technology that has been used successfully for years in similar cases. Put your trust in our proven solution for a clean and odour-free environment!
