Nature’s best cleaners

Meet Acidithiobacillus Thiooxidans.

This bacterium, together with many others, forms an extremely effective natural processor, which 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 process control optimizations allow bacteria to function under extreme conditions

High Performance Bioreactors

In over 20 years that we have been active in biological emission control, we always have found ways to improve our technology and make our products more economical.

A list of patents is proof of our innovative power. The heart of the AZZURO solution are our two high-performance bioreactors, TORRENTA for aerobe applications and SULFATECH for anaerobe applications. However, we have also expanded our product suite to include a hybrid bio-chemical reactor for ammonia treatment (AMOTEK), an activated carbon filter (AZZORBO), and a compact combination system for limited spaces (PURETTA).

Key Benefits

  • Stackable color-coded media creates an optimal void volume to biological area ratio
  • Modular design keeps our bioreactors fast and easily configurable
  • Zero maintenance solution does not degrade performance for years
  • Meets all requirements and regulations easily, improving LEED scores
  • Short ROI period makes for an economically sound investment

The best performing media on the market

Available as part of our High-Performing Bioreactors or a separate item to anyone looking to replace your current media, AZZURO’s Color-Coded Spacious Wire Pac Media is fully synthetic, does not deteriorate or clog, and is not hindered by fouling. Each color layer represents a different material, which can be combined in endless “recipes” depending on your emission needs. This unique approach is only offered by AZZURO.
