Biothane® - The First High Rate Anaerobic Wastewater Treatment Technology Installed in the USA
Veolia's advanced Biothane anaerobic wastewater systems are a well-established technology in its field. These technologies meet today's ever-increasing demands for low operational cost, small footprint, low sludge production and energy recovery.
Since 1972, almost 700 Biothane installations have been implemented in more than 40 countries worldwide. The dedicated staff at Veolia has extensive experience in designing and engineering anaerobic treatment solutions for industries throughout North and South America.

Stable and Reliable Anaerobic Digestion
Biothane high-rate reactors are the leading technology for anaerobic granular wastewater treatment processes which realizes the potential in wastewater for energy (biogas), nutrient recovery and water reuse. Based on more than 40 years of experience, having more than 550 references, the next generation of high rate anaerobic technologies have been established. Both the Biothane Advanced UASB and Biobed Advanced EGSB proven to have a most reliable, stable and high performance against a high cost-effectiveness.
