FennoDose monitors water in paper plants case study

FennoDose, a small-scale automation solution developed in Kemira’s research center, monitors water quality and controls water chemical use in paper plants.

Clean water is critical for processes where paper pulp moves along the web at highway speed. Impurities would pose a serious threat to a system involving large masses, high pressures and extreme temperatures. The system automatically measures how clean the water is, for example, at the end of the process. If the amount of impurities exceeds the default level, FennoDose increases chemical dosage. Without automation of this type, paper plants would need to use chemicals as a precaution, unaware of the real need. After implementing FennoDose, some paper plants have been able to improve the efficiency of chemical use by several dozen percent.
