Odour control is one of the primary concerns of large-scale waste treatment facilities, especially those located near sensitive areas. While good process management and careful plant cleaning can greatly reduce odours, in many cases some method of odour treatment will still be required. Biofiltration has found to be the most effective and economic treatment option, which has led to its widespread use in the composting industry.
Biofiltration is a biological process that reduces the odours present in the process air using a mixed microbe population, including bacterium, mildews and yeasts that work as a natural cleaning agent.
- it is completely natural process: chemical substances of synthesis are not used. Through its biologic and not chemical processes the biofilter can reduce different types of odorous compounds.
- it is easy to instal and doesn't requires any special utility or civil works.
- low energy cost: the high porosity make the pressure drop very low and consequently makes the energy consumption low.
- low maintenance: only periodical tests are necessary to check the temperature and humidity of the biofilter media.
- long duration: the filtering material has to be subtituted every 4-5 years. At the end of its working life, the disposal of the biofilter media has no environmental consequence
- high reliability: the Entsorga's biofilter is proven by a relevant number of installations and by the related of data available.
