Winning case of 56,000m3/hr of air treatment

In a challenging wet and muddy site at Blaise Farm in Offham, Kent, we were able to complete the assembly of two of our ColdOx systems, which combined will treat over 56,000m3/hr of air from the new waste reception and depacking building for this new Bioconstruct Biogas plant.

 

An amazing effort from the team of just an average of three people over four days. Again indicating how little site time our systems require for assembly, coming flat pack from Sweden. The system just awaits the finishing touches of ducting and power leading to it.

Growing Interest Over the Years

 

This year it is the 3rd time Centriair had been exhibiting at Pol-Eco systems. Besides all the interesting contacts we had made and positive feedback we had received from the visitors, one fact had made us very happy. The number of visitors to our stand had almost doubled compared to last year. The reason behind such success is not only the marketing and sales works that had been done over the years, but also the overall interest in the Polish market towards a better smell free environment. We are truly happy to witness a transformation in the society where odour free community is no longer a luxury, but rather a must.

Centriair exhibits in Japan for the first time

 

It has been a great honor to exhibit in Green Energy Week Osaka, Japan. Various industries such as Biogas, Waste Recycling, Waste-Water Treatment and even Food production had demonstrated a great interest towards our ColdOxTM system.

 

With recent tragedy in Fukushima, the country is rapidly transitioning to green energy. Considering the density of the population, the local authorities are very well aware of the smell problems and all the inconvenience they can lead to. At Centriair, we feel ready to take on a new market such as Japan since it shows tremendous commitment to removing odour and view us as “the modern innovation” company.

Challenging Odours within Biogas

In a modern world, Biogas has the potential to replace a large part of fossil fuel consumption. The possibility to generate energy from a wide variety of sources, environmental impact and profitability create an attractive ground for more and more companies to invest in the renewables industry. A good example of such a biogas plant is in Alvesta, Sweden. This plant specializes in turning slaughterhouse waste into an effective source of energy which powers up local houses and businesses in the surrounding area. While being one of the most strategically active plants in the municipality, Alvesta Biogas started appearing in the news, however not in the light they wanted to.

 

The process of generating slaughterhouse energy starts with the storage of the biomass in hygienization tanks. During this process the biomass is heated up in order to remove the liquid elements from the material as a pre-processing stage. As a result of that heat, a strong and irritating smell started to escape the tanks and the facility and spreading around the neighbourhood communities. This has caused a mass outrage with continuous complaints and threats from the municipality. The Biogas plant is now threatened to be shut down which could leave the area without energy supply and the workers unemployed.

When Scandinavian Centriair AB had received the request to help Alvesta Biogas solve their odour problem, nobody knew what was going to come. With extensive experience in the field of waste and biogas, Centriair experts assumed that the presence of H2S, Ammonia and other Volatile Organic Compounds (VOCs) would be the main elements causing the unpleasant smell. Since the customer has not done its odour measurements, Centriair team together with ÅF consultants had gathered samples which were later analysed in the lab. The results were shocking as the VOC concentration has showed 8 000 000 OU and 8 000 ppm H2S in the gas stream. To get an idea of how unpleasant that smell can get, we can say that at 0,000047 ppm of H2S a human nose can already detect the odour. According to the statement of ÅF consultants, this had been the highest VOC concentration that they have witnessed in Sweden.

The task was not easy since there are very few technologies in the market that can handle such extreme concentrations. For Centriair there was only one solution: DEO™ – catalytic conversion technology. DEO-100™ is a regenerative catalyst system for elimination of VOC and odour emissions from industrial processes. VOC and odour compounds are eliminated through patented mesh catalyst technology allowing for optimized and compact reactor geometry, large catalyst area and heat capacity. After the installation the smell seemed to disappear, and it became more bearable to stand around the plant. Knowing all the challenges of this application, Centriair team has done another round of sampling at the outlet of the DEO-100™ system. The test results indicated 99,6% reduction rate on VOCs and H2S compounds with less than 1 OU/M3 in the distance of 200 meters from the plant. This was a win-win situation for everyone.

In conclusion it is important to point out the necessity of odour treatment within Biogas plants. Alvesta Biogas is a good example of how ignorance of the problem could lead to sever consequences. It does not matter what a plant decides to use as a feedstock: it could be manure from animals, green waste from farms, sewage from the waste water treatment plants, it will all generate unpleasant smell for the staff and for the unlucky people living around biogas sites.

Installation works at Wardley Biogas

Our installation works at Wardley customer site will be finalize this week. We are proud to be a part of such an amazing project where once again we have accomplished our mission of creating an odour free environment for the employees and the surrounding communities near the biogas site.

New Project Engineer at Centriair

Tobias has studied product development with specialization in mechanical engineering at Blekinge Technical College (BTH). He has a wide work experience that includes a variety of practical jobs such as technician, but also as an entrepreneur and engineer.

 

His role at Centriair is as a project engineer and his job is to strengthen our projects department in various strategic ways.

New Order Received

Centriair has received an order to treat odour from the waste and water company in Norrköping, 8th largest town in Sweden. The project includes odour treatment from a sludge storage tank and the main intake pumping station.

 

The long term reason is that new housing will be built in the attractive land next to the WWTP right by the river in Norrköping. For more information please contact us at

WARDLEY SELECTS CENTRIAIR AB AS CONTRACTOR TO SUPPLY DEODORIZATION SYSTEM

 

We are happy and proud to have been selected as odour treatment suppliers to the new Biogas plant project by Bioconstruct from Melle, Germany. The site is Wardley, a considerably larger plant than the previous project together treating in total a 64 000 m3/h air flow. Our team of highly skilled engineers have already started the design and production of 3 ColdOx TM systems as well as a smaller DEO TM catalytic solution for extreme H2S concentrations.

Marodour TM as a successful innovation from Centriair AB

 

On March 17th Centriair has installed yet another Marodour unit at a local pumping station in Portugal. The unit is running at 300 m3/h with an estimated odour reduction rate of 95%. It is is important to mention that this is the 4th Marodour installation within the last quarter where in all cases customers have responded positively on the performance of the unit.

 

Marodour is the latest addition of odour treatment products from Centriair AB.
Thanks to its relatively small size, it is easy to install in waste rooms, pumphouses
and other facilities with limited space. The equipment treats odour with a
combination of Cold OxTM and Active Carbon. The technological innovations
from Centriair allows the carbon filters to be recharged through the ColdOx
treatment increasing performance and the lifetime of carbon compared to other products in the market. Read more about MarodourTM here.
