Membrane production processes are very complex and require the availability of the right data at the right time. This has a direct impact on product quality and production efficiency. The main challenges are the storage of process data at a high resolution and integration of data from different process steps. One more challenge is the need to meet the growing customer requirements with regard to product quality and consistency. The benefits of PI System for process data aggregation, analysis and use in continuous real-time process monitoring and process optimization in combination with Sartorius Data Analytics Solutions will be shown.
