Case Study: Södra Cell Mönsterås achieves 75% fiber savings with Valmet screen room rebuild

Södra Cell Mönsterås cuts fiber loss 75% with Valmet

Södra Cell Mönsterås, one of the world's largest producers of TCF bleached kraft pulp, was facing a significant challenge with its screen room, losing approximately four tonnes of accept fiber daily during softwood production. The mill selected Valmet to solve this problem.

Valmet rebuilt the mill's third screen and replaced cyclone cleaners with a fourth screen, adding a screen basket with a dilution belt. They also replaced a number of cyclone cleaners with an OptiScreen Fine screen. This solution from Valmet resulted in a 75% reduction in fiber losses, saving about three tonnes of fiber per day. This dramatically improved the mill's profitability, resulted in a payback time of one year or less, and made production more environmentally friendly through reduced water usage.
