Effective treatment of industrial air emissions is a challenging task 

Each process is unique and so are the emissions coming out of the stack. Meticulous in-house pilot tests are needed to find the optimal air treatment solution.

H₂S and odor removal at biogas plants

One of the challenges of biogas plants is the strict requirement of H₂S removal after the anaerobic digestion stage, before upgrading. Another constant source of concern is the odors emitted from the biogas plant. Today, both can be solved effectively, and green. Let us help you.

Innovative modular system for effective odor removal

Nodora is our latest innovation for air treatment. It is a modular and flexible system for all types of odor problems and can handle both large airflows and high loads. Nodora is a complement to our family of RENA ozone systems and offers tailored solutions for both industry and commercial real estate. Download the brochure and read about the opportunities that Nodora creates.

Odor reduction for biogas plants

A biogas plant produces a lot of smells in its operations. For example, at the reception, sorting, hygienization, digestion, discharge, etc. These smells often disturb the adjacent areas and may also be harmful to those in the plant. The RENA Pro system offers an effective solution. Download the brochure to read more.

Case Studies

Description

Elimination of black mold at dairy facility

Located in the small town of Dovre is the TINE dairy company where soft white cheese is produced. The facilities exhibited extensive black mold growth in various locations, especially in the storage warehouse. The whole production process was sub-optimal, with difficulties in predicting the annual production.

No more H₂S emissions from the pump station at the harbor in central Stockholm

In Masthamnen in central Stockholm, passenger ferries dock after cruising in the Baltic sea. The problem was related to their wastewater, discharged in the nearby pump station, prior being transferred to the wastewater treatment plant. The pit of the pump station was not completely sealed which led to the discharge of H₂S from the water.

Odors from H₂S brought down to zero by combined catalysis and ozone treatment

Our Rubicat™ catalyst was used in this version of the Nodora Cat. It is designed to selectively remove H₂S from polluted air streams, even at high concentrations. Ozone was used as final polishing step, ensuring zero odor emissions. The ozonation step included three RENA Pro ozone systems.

When nothing else worked, our solution combining ozone and UV did

A new processing method caused major odor problems for the surroundings. The problem was not only that the compounds were very difficult to remove, the extreme concentration of pollutants (3400 ppm) made the task seem impossible.

Ozonation and Nodora ADS solved the odor problem

The company produces biogas and biodiesel from a combined plant for treatment of organic residues from food industry. Their key industrial stages are a continuous dry anaerobic digestion process and a supercritical esterification process. The treatment capacity is about 20,000 tons per year of residues, producing 200 m³/h of biogas raw gas.

Case with detailed graphs comparing H₂S concentrations before and after we were called in 

This case from a wastewater treatment plant includes interesting treatment results. The concentrations of hydrogen sulfide were measured at three occasions: with no air treatment, with the former suppliers’ ozone treatment and with our ozone treatment. The RENA Pro system solved the task, the H₂S concentration dropped 87% - have a look.
