Delta-pH-Measurement for decarbonisation control

Water treatment plant Hofheim

The problem

The drinking water sources of Hochheim in the German Taunus region contain high amounts of aggressive carbon dioxide that have to be removed by means of a stripping process. Since the water is a mixture from various wells, the carbon dioxide content varies, and the deacidification has to be adapted to the changing requirements.

Our solution

The stripping process is controlled with a measuring system K400 delta-pH by Dr. A. Kuntze GmbH. This ready-to-use Automatic Analyser measures the carbon acidity via delta-pH measurement according to DIN 38404-C10. Due to a periodic and automatic alignment of the two pH sensors the Analyser requires very little maintenance.

Customer´s feedback

"Measurement and control work efficiently. Maintenance is carried out twice per year by Dr. A. Kuntze. We have made positive experience with both the product and the company."
