Case Study: Sappi achieves higher productivity and improved washing efficiency with Valmet wash press upgrades

Sappi boosts wash press productivity with Valmet, cutting COD by 19%

Sappi's Gratkorn mill faced challenges with plugging and reliability in its fiberline wash press. To address this, the customer partnered with vendor Valmet for a tailored upgrade, selecting Valmet ProNip and Valmet Inlet ProFlow solutions to improve performance.

Valmet implemented a mechanical upgrade that allowed for operational nip adjustment and a new inlet system to minimize plugging. The results were highly successful, with Valmet's solution increasing inlet consistency by two percentage points, reducing Chemical Oxygen Demand by 19%, and significantly boosting washing efficiency and production reliability for the mill.
