Safe and effective odor removal

Vegger Biogas is Denmark’s oldest biogas plant, built in 1986 as part of the Danish Village Energy Plan. They completed a major expansion in 2014 and needed to replace the old bark filter system with a safe and efficient biofilter that could match a much larger odor generation and meet the authorities’ stricter requirements for odor removal.

In the tender phase, BBK was the only biofilter manufacturer that could guarantee odor-free systems without complaints from neighbors. During the design process, there was a close collaboration on the design of air ventilation, where BBK used smoke fogs to specify point extraction and piping, among other things. Therefore, the new facility was fully upgraded from day one.

The biofilter is built in 2 sections in concrete elements. BBK supplied the extraction system/piping, buildings and filter solution.

Capacity

150,000 tons of biomass/year

Production

7.1 million m³ biogas/year

Filter capacity

30,000 m³ /hour

Dimensions

Pre-filter 45 m²
Biofilter 230 m²

Lifespan

8 – 15 years depending on concentrations in the air fed to the biofilter.

“Our ambition was to provide cheap energy to the village and not expose the neighbors to odors. We have fully achieved this. After a smooth BBK delivery, we now have a service contract with quarterly visits and technical service. BBK is often at the forefront of improvements and the Environmental Inspectorate has never had a critical remark during inspections. I don’t remember a single point of criticism in our collaboration where we talk straight. It just works”.

Sustainable biogas production

Vegger Biogas converts sludge, manure and biological waste into biogas. Built for 60 t/day biomass, it has now been expanded to 400 t/day. The much larger volumes handled in a small urban community place high demands on process containment and a tight piping system to extract odors from tanks, warehouses, etc. so that all odorants are removed in the filtration system and nothing escapes.
