Valmet Oxygen Delignification system removes lignin with excellent efficiency. It is the ideal oxygen delignification stage and a great asset for pulp mills. Up to 65-70% of the remaining lignin after cooking is removed. This result remains unchallenged. The secret lies in the carefully optimized conditions.

Screening
Valmet’s pulp screening systems are characterized by high capacity, high shive removal efficiency and excellent runability. Screening pulp at the highest consistency possible is the basic idea behind our unique screening concept. This results in a substantial reduction of the amount of water that has to be handled. Less water makes it possible to build more compact machines, which also means lower installation costs and energy savings.
