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.

Mold and odor removal

Mold spores not only cause stale and bad odor, but is also a source of ill health and allergies. In poorly ventilated areas with increased humidity, the mold can easily attach and cause inconvenience a long time before it is visible to the eye. Our ACT 3000 and ACT 5000 ozone generators can handle the problem.  

Odorless garbage rooms and grease traps with ozone

Ozone is an effective and low-cost method to eliminate odors. The purchase and the operating costs are very low – which makes the total cost over time significantly lower than for cleaning solutions based on cooling and bacteria. Ozone is the best choice for garbage rooms and grease traps.

Fresh garbage rooms without odor and cooling

Garbage rooms, garbage sorting rooms and similar spaces naturally suffer from bad odors. But it doesn't have to be that way. Download the folder, it includes a cost comparison for the major solutions available on the market. Not surprisingly, ozone takes care of the odors at much lower cost than the alternatives.

Odorless deaeration from grease trap

Fat and bacterial formation in the grease trap can cause major odor problems. This brochure tells how the problems can be quickly reduced, and how to install the ozone system.

Pump stations and treatment plants

Bacteria growth in wastewater can lead to unpleasant and malignant gases under acid-free conditions. Two examples are hydrogen sulfide in pump stations and treatment plants. The area surrounding a pump house or water treatment plant is also affected. It is not rare that people living nearby are affected by the odors. 

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.

Solved: Hard-to-treat odor emissions from innovative wood processing company

Up to 3400 ppm of compounds including pinenes, limonene, hexanoic and heptanoic acids.

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.

Vasakronan uses ozone to increase energy efficiency

Vasakronan employed Ozonetech to reduce energy consumption and cost in the Skrapan building in central Stockholm. After only three months, the investment was paid and started to generate profit each month.

No more odors from the 1900th century restaurant

Restaurant Godthem, on the Royal Djurgården, opened 1897. They installed a grease trap hundred years later when it became mandatory. Since then grease started to accumulate and cause odor problems. These were easily solved by installing an ozone solution for air purification.

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 three times: with no air treatment, with the former supplier’s ozone treatment and with our ozone treatment. The RENA Pro system solved the task, the H₂S concentration dropped 87% - have a look.
