Drinking water system: Modernization during operation

As the water pumped for the Giessen in Hüttingen did not meet the requirements of the drinking water ordinance with regard to the pH value, a deacidification system had to be installed. At the same time, the entire plant was modernized. However, since the drinking water should always be available to residents, the renovation and modernization measures had to take place during operation. The automation solution developed by Public Utilities Gießen consisted of the monitoring and control system TeleMatic with embedded controllers from Beckhoff and the process control system SCADA V10 (HydroDat), both from HST. The production processes are now continuously monitored by control and automation processes. Even a short-term optimization of the promotion is thus immediately possible. The fully automated and unattended operation makes a significant contribution to the reliable supply of consumers with deacidified water and also improves the economic efficiency of the system. After a good six months, the remodelling and modernization work was successfully completed. The implementation was carried out by Passavant & Watec – a solution partner of HST.
