Traditional odour treatment systems use a trickling filter with an additional biofilter (bio-bed), which entails first passing the air to be treated through the trickling filter and subsequently through the bio-filter. The BTC tower® is a biofilter and a trickling filter in one. A combination which is filled with a biological filter media suitable for biological odour treatment.
Advantage: Using this tower requires approx. 25% of the working area and approx. 35% of the filter media compared with the working area and filter media used for a traditional (flat) biofilter.
Gases to be treated: NH3 (ammonia), H2S (hydrogen sulphide), VOC (volatile organic compounds), hydrocarbons, etc. The tower can also be used as an organic biological biofilter. No chemicals are used at all, which means it is an extremely environmentally friendly solution for odour control.
The filter media used is heather. Heather is a natural product that contains natural bacteria, which make it ideal for odour control, and contrary to other commonly used filter media, is naturally scented.Heather has a specific surface area (1000-1500 m2/m3) which is significantly higher than other filter media (e.g. root wood and bark, which have a specific surface area of 250-500 m2/m3). The start-up time for heather is therefore much shorter (approx. 1 week) than e.g. root wood or bark (2-3 months). There is consequently no odour nuisance during the start-up of the biofilter.
