Metso to supply pulp washing technology to Rosenthal, Germany

JYVASKYLA, Finland, Aug. 25, 2008 (Press Release) - Metso Paper has received an order to supply technology for improving pulp washing at the Zellstoff- und Papierfabrik Rosenthal GmbH mill in the province of Thuringia, in central Germany. The modernized fiber line will be taken into operation during the second half of 2009. The order value is not disclosed according to an agreement between the two partners.

The order includes two TwinRoll wash presses. One TwinRoll press will be installed to improve the brown stock washing. The other TwinRoll press, with improved washing efficiency while retaining higher consistency, will be installed in the ozone bleaching stage. This enables continuous efficiency of ozone utilization.
