BIOLOGICAL WASTE-GAS TREATMENT in TRICKLE-BED REACTORS using LEVAPOR

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.
