Bleaching and bleached stock screening modernization at Modo Hallein, Austria
Published June 28, 2000 00.00.00 +2 GMT
Modo Paper Hallein mill, located in Austria, produces Mg-bisulphite pulp from spruce as the raw material. Some time ago the mill prepared a plan to enhance their bleaching and bleached stock screening processes. In December 1999 Valmet carried out full-scale trials at the mill with DeltaScreens to prove that re-screening can effectively operate at over 2.5% consistency. After successful trials, the DeltaScreen installation was adopted as part of the second modernization step, called "Kreislaufschliessung – Teil 2". The main objectives for the overall modernization are:
· to improve pulp cleanliness · to reduce carry-over · to close the bleaching process
The second investment step, ordered in April this year, includes DeltaScreens, Valmet TwinRollTM DPA wash presses and tower equipment for final bleaching.
The line is designed for 460/ADT/d capacity and the start-up is going to take place in April 2001.
