HUBER Active Carbon Filter CONTIFLOW® GAK
The HUBER Activated Carbon Filter CONTIFLOW® GAK is a continuous activated carbon filter designed for advanced wastewater treatment, with a focus on removing dissolved micropollutants. The filter uses granular activated carbon (GAC), which effectively adsorbs a wide range of organic micropollutants, including pharmaceutical residues and other contaminants of emerging concern.
CONTIFLOW® GAK is designed for continuous operation and is typically applied as a key treatment step within quaternary treatment. The solution delivers high and stable treatment performance and is well suited for both municipal and industrial wastewater treatment plants where stringent effluent quality requirements apply.

Applications
- Quaternary treatment for removal of micropollutants
- Post-treatment of biologically treated wastewater
- Compliance with stringent discharge requirements
- Municipal and industrial wastewater treatment plants
Benefits
The HUBER Activated Carbon Filter CONTIFLOW® GAK is designed for reliable and efficient adsorptive treatment, with a strong focus on the removal of dissolved micropollutants and stable long-term process performance. Continuous operation allows the filter to run without periodic shutdowns, ensuring uniform loading of the activated carbon and a predictable treatment efficiency over time.
The filter can be easily integrated into existing process lines and is typically installed downstream of mechanical and biological treatment – often following particulate filtration – to ensure optimal operating conditions for the activated carbon.
- Effective removal of dissolved micropollutants through adsorption
- Continuous operation without periodic shutdowns
- Stable and consistent treatment performance
- Well suited as a key process step in quaternary treatment
- Robust and reliable solution for long-term operation
- Can be combined with pre-filtration to optimise activated carbon utilisation
