Treating dewatering water during construction works is complex: in addition to PFOS, substances such as sand, iron, and other natural contaminants are present. Without pre-treatment, the activated carbon filters would quickly become clogged and lose their effectiveness. Moreover, the installation had to be flexible and modular, allowing it to scale up or be adapted to the needs of the construction site. The ability to enable remote monitoring was also crucial, so that technicians would not always need to be present on site.
The treatment concept was built using container units, with each container performing a separate process step. Infrasoft ensured that each container was equipped with a Siemens PLC and its own HMI touchscreen, allowing the containers to operate fully autonomously.
All PLCs were connected via a redundant ring network, ensuring that the installation remained operational even in the event of a failure. For remote monitoring, Infrasoft implemented a VPN connection via Sinema RC, enabling the client to remotely monitor and manage the installation status.
In addition, a WinCC OA SCADA system was developed to provide operators with a clear overview of the installation’s performance, filter statuses, and any alarm notifications. This not only ensured transparency but also enabled proactive maintenance.
Thanks to Infrasoft’s solution, the pumped groundwater was effectively treated, with PFOS and other contaminants reliably removed from the water. The modular container-based setup provided maximum flexibility and allowed for easy expansion or adaptation during the works.
The combination of PLC programming, SCADA development, and network architecture ensured a safe, robust, and remotely manageable installation. As a result, the client maintained full control with minimal on-site presence.
This project demonstrates how Infrasoft leverages its expertise in process automation, SCADA, and remote monitoring to support complex challenges in infrastructure and environmental projects.
