Overview
The HYDROZON® drinking water compact units are suitable for almost all areas of use relating to drinking water treatment with filtration. Problem-oriented, fully-automatic systems can be implemented utilizing modular design. A rough distinction can be made between the following treatment processes:

Drinking water treatment with compact units
