The HUBER Active Carbon Filter is that it has no influence on existing process-engineering systems on the sewage treatment plant and can be optimised further by adding a "classic" CONTIFLOW® Sandfilter or an upstream ozonisation plant.

HUBER Active Carbon Filter CONTIFLOW® GAK

It is used as a quaternary treatment stage on sewage treatment plants and removes micropollutants from the wastewater flow. The system uses granulated active carbon and is installed downstream of the secondary clarifier.
