How does Azzuro’s
High-Performance
Torrenta Bioreactor
work?
Contaminated air is introduced at
the bottom of the reactor
The air passes upward through
one or more microbial beds and
clean air is discharged at the top
of the unit
Humidification is accomplished by
way of an advanced water
spraying system designed to
maximize growth of the biomass
Foul air/Odorous air compounds
are quickly degraded by the
microorganisms, eliminating the
emission problem
For all Aerobe Applications

Modular Design – the Torrenta Series
• Standard modular design:
• Locally sourced materials
• System is easy to expand for
future growth
• Simple installation
• Constructed of non-corroding
materials
• Size depends on application
We recently introduced the Torrenta TR 42-9
A single reactor capable of treating an unparalleled 41.200 cfm!
An environmentally friendly solution aligned with global initiatives – Integration of green functionality into existing processes

AZZURO’S Sulfatech - Process Description:
The key of this technology is the "Anaerobic-Aerobic Biological Wheel (= Biological Recirc System)". The system uses two
different phases (i.e. anaerobic and aerobic) of biological activity to have H2S removed from Biogas or Flare Gas or other
gases.
