Our industrial filters are used in a wide range of applications. We carefully select the best-suited highperformance carbon, or catalytic media, for each application. Eg. when H₂S is the cause of the problem, we select specially prepared impregnated activated carbon, while we use our tailor-made catalytic material (RubiCat™) for desulfurization in biogas applications.


Nodora Advanced air filtration

Having delivered tailor-made odor treatment systems for demanding industry applications, we realized the
need of a standard industrial grade modular solution applicable for both industrial and real estate applications. So we designed one. The result: Nodora – a modular, highly efficient and compact system. The perfect solution when space is limited and odor must be minimized.

Nodora CAT solved a delicate case with high H2S emissions in a crucial location

H2S was effectively removed with the Nodora CAT, with emissions well below the limits, since the installation. For many weeks, an H2S sensor was placed at the outlet of the treatment system validating the performance. No significant values of H2S were observed. Even if a tolerance up to 10 ppm was accepted in the process requirements, the Nodora CAT removed 100 % of H2S even during the highest loads.

The synergy between catalysis and ozonation ensures H2S and odor-free emissions

Mellifiq provided a complete H2S removal treatment and filtration system for the wastewater treatment plant of the city of Leksand, Sweden. With the combination of ozone treatment and Nodora CAT, 100% of the H2S was removed together with the remaining odors.

No resident complaints, reduced energy cost and less environmental impact

Final odor treatment and energy recovery in new city center nightclub.
The projected kitchen exhaust air was to be led into a residential area – a courtyard where the apartment balconies are located just above the restaurant. As the exhaust location had been noticed by the residents and being a top-class player in the Swedish entertainment business, Stureplansgruppen was determined to eliminate the risk of complaints and negative publicity. An Ozonetech RENA Kitchen Solutions together with our catalytic mixed-bed filter Nodora was the perfect match for the mission.

The combination of ozonation and selective adsorption removes all gas pollutants

Rebuilt biogas plant with zero disturbing odor emissions

The Finnish biogas plant owned by Biopower OY decided to not risk having complaints because of odor emissions. With the installation of Nodora ADS, this result was achieved flawlessly.

The benefits of highclass odor removal

An innovative solution was presented in the early planning stage: to recover the heat from the kitchen exhaust to heat up both the mall and the underground garage.
