TECHNOLOGY INFORMATION

About the eXeno™

Conventional wastewater treatment plants are not designed to specifically remove micropollutants from wastewater. Additional treatment is required which typically uses strong oxidizing agents such as ozone or adsorption through activated carbon. But there is a more sustainable way to tackle this challenge.

Biological treatment of micropollutants 

Our patented eXeno™ technology uses specialized microorganisms to biologically degrade micropollutants with less or no chemical dosing and low energy consumption.

eXeno™ is an MBBR (moving bed biofilm reactor) technology that typically consists of multiple bioreactors in series. Each reactor contains a moving bed of specialized bacteria growing on carriers that target a wide-variety of complex compounds. In the first stages, more easily degradable compounds are removed while the more difficult compounds are removed in the succeeding reactors.

High-Performance Wastewater Technology to Protect the Environment

This advanced biological wastewater/micropollutant treatment technology enables the development of biomass with significantly longer sludge retention times compared to conventional systems. This encourages the development of slower-growing organisms capable of removing difficult pharmaceuticals and other micropollutants. 

eXeno™ solutions range from complete treatment including carbon and nitrogen removal of pharmaceutical/industrial wastewater and hospital wastewater to tertiary solutions for municipal applications.
