Customer case:

Polymer saving by Valmet Total Solids Measurement

Marusumi Paper is a Japanese newsprint company producing 1460 tons per day. Until now, their wastewater treatment section had no online measurement of screw press dewatering machine fed sludge.

Marusumi Paper saves polymer dosage with Valmet TS
Previously, the amount of chemicals added had to be changed based on the results of regular sampling and manual analysis, but the online measurement enables a rapid response to changes in operating conditions. This has eliminated over or under-addition of chemicals and contributed to the stable operation of the equipment.
