Polluted and odorous waste and exhaust gases can be removed most cost-effectively through biological treatment. High-performance biological waste-gas treatment plants are required to fulfil several tasks:
- Rapid adaptation of the microorganisms to the hazardous organic compounds (chlorinated hydrocarbons, amines, mercaptane, etc.),
- Neutralisation of the biologically formed acids HCl, HNO3 or H2SO4,
- Good () supply of the biomass with nutrients,
- At low energy consumption.
These requirements can be readily met with the support of modern
- TRICKLE-BED REACTORS, through
- ADAPTED, SPECIAL BIOMASS,
- IMMOBILISED with adsorbing, porous LEVAPOR carriers
Adsorbing, porous LEVAPOR-carriers measuring 25 x 25 x2 5 mm
- Weigh dry only approx. 30 bis 40 kg/m³,
- Absorb over 250 wt.% water (very important for bioactivity!),
- Suffer no loss of pressure,
- Rapidly bind special organisms and the substances to be degraded,
- Rapidly achieve maximum performance very quickly,
- Last for over 10 years.
