Stora Enso Heinola: Continued investment in the best technology

The Heinola Fluting Mill is part of the Stora Enso Renewable Packaging business unit. Continuous investment in best available technologies has been a key factor in maintaining the mill’s reputation as one of the world’s best and most productive semi-chemical fluting manufacturers.

Polymer dosage is now under accurate control and overdosage is avoided. Similarly, the centrifuge filtrate purity is better than before."
Timo Riuttanen, Heinola mill operations manager
Location Heinola, Finland
Customer challenge Increasing the effectiveness of process control and minimizing negative environmental effects.
Solution Valmet Total Solids Measurement (Valmet TS) and Valmet Low Solids Measurement (Valmet LS)
Results Polymer dosage is controlled in relation to suspended solids load based on the solids content of the centrifuge reject water. It is thus possible to obtain a better degree of separation and minimize the internal circulation of suspended solids.
Keywords Wastewater, Automation, Europe

Product and company names changed from Metso to Valmet. Valmet acquired Metso’s Process Automation System business and products on April 1st 2015.

Total Solids Measurement

Valmet Total Solids Measurement (Valmet TS) is a reliable and accurate microwave real time measurement used to control and optimize the solids treatment process, giving operators information on the total solids 24/7.

Low Solids Measurement

Valmet LS, a low solids measurement, is the only meter that works for centrate suspended solids, saving polymers while optimizing the wastewater treatment.
