Nature’s best cleaners for biological air pollution

Meet Acidithiobacillus Thiooxidans.

This bacterium, together with many others, forms an extremely effective natural processor in our biological air pollution control process. It purifies waste air of odors or hazardous components. Our microbial technology was developed over years of collaboration with major US and European universities. The result is an efficient and rugged biological system that naturally treats a variety of emissions for years without degraded performance

Key Benefits

  • Major developments done in cooperation with world-class universities
  • Extensive process knowledge grants us the best selection of biology
  • Over 20 years of biological development transformed lab and field cultures into “super bugs”
  • Constant biological air pollution control process optimizations allow bacteria to function under extreme conditions

High Performance Bioreactors

For more than 20 years, we have continuously enhanced our technology, making the biological air pollution control process both efficient and cost-effective.

Our list of patents further highlights our innovation. At the heart of AZZURO’s solutions are two high-performance bioreactors: TORRENTA for aerobic applications and SULFATECH for anaerobic systems. In addition, we have expanded our product line to include the hybrid bio-chemical reactor (AMOTEK) for ammonia treatment, the activated carbon filter (AZZORBO), and the compact PURETTA system, ideal for limited spaces.
