The biofilter intended for biological clearing and removal of odours of the industrial air-gas emissions containing organic components of the various nature.
Scopes: chemical, paint and varnish, manufacture of rubber, furniture, tobacco, wood-working, food, etc. manufactures.
The production engineering of clearing of air-gas emissions sets up on decomposition by microorganisms of the harmful organic matters contained in an air-gas mix and being the energy source for biomass. Organic joints decompose on carbonic gas and water. Selection of consortia of microorganisms is carried out depending on composition of cleared mixes.
Total concentration of hydrocarbons in cleared gases should be in limits from 400 up to 7000 mg / m3.
At a dustiness of cleared outtake emissions more than 5 mg / m3 installation of preclearing of a dust is necessary.
Installation is maintained at temperature of air indoors from +18 up to +35 0С, a relative humidity up to 60 %. Temperature of a working zone + 25 … 35 0С, optimum value 28 0С.
