High-Performance Bioreactor for Aerobe Applications

Benefiting from 20 years of development, TORRENTA is a biotrickling system used in a broad range of industries and applications, including municipal and industrial wastewater treatment, F&B, and petrochemical.

Our number one selling bioreactor

TORRENTA is a counterflow Trickling System for a wide variety of air cleaning solutions that guarantees a stunning removal result year after year, without media replacement. First introduced in 1998, the technology has now been used to benefit almost every industry – consistently bringing each plant’s emission within permit values. In many cases, TORRENTA has replaced conventional chemical scrubbers and carbon filters due to its reliability and cost savings.


Aerobe biotrickling system mainly used to treat odor and toxic sulfur emissions


Removes over 99.5% H2S and other toxic sulfur compounds


Flow rates up to 20,000 cfm and H2S concentrations up to 20,000 ppm


An adaptive and self-regulating process that uses no chemicals and operates at ambient temperature and pressure


Consistent performance, few moving parts, extremely high reliability, and near zero maintenance


Modular design easily configurable for a wide range of applications

Cost Savings

Simple installation, minimal disruptions to operations, and reduced steam consumption allow CAPEX to be recovered in as little as 24 months

The torrenta Process

Patented Technology

Contaminated air enters the bottom of the reactor, passes upward through one or more microbial beds, and exits the top of the unit as clean air.

During this process, an advanced water spraying system maximizes growth of the biomass through humidification. As the contaminated air travels up the TORRENTA tower, microorganisms quickly degrade the foul/odorous air compounds, eliminating the emission problem.

The last stage consists of an ultra-dense biological surface area specially designed to polish the air before emitting it into the atmosphere.
