Activated Carbon
Activated carbon is one of the established methods used in the fourth treatment stage. Depending on the requirements, either powdered activated carbon or granular activated carbon is used.
Both types enable the reliable removal of organic micropollutants and can be adapted to different plant designs.
Powdered Activated Carbon (PAC)
Low capital costs
Flexible application
Compact design
Can be used temporarily
Granular Activated Carbon (GAC)
Can be reactivated
Compensates for concentration fluctuations
Easy to handle
Can be used as a safety stage
