International technology Group ANDRITZ has received an order from SCA Hygiene Products GmbH to supply equipment for the expansion of the deinking plant for paper machine no. 4 at its Ortmann mill, Austria. Start-up is scheduled for June 2012.
The scope of supply for ANDRITZ is a complete dispersing and high-consistency bleaching stage (screw press, CompaDis disperser, and high-consistency bleach tower including screw conveyor transport system), rebuild of the low-consistency cleaner plant and disc filter, process pumps, installation, start-up, and training.
The deinked pulp will be used to produce toilet tissue. This investment iand the expansion to a two-loop deinking system will give the mil a significant brightness increase in the tissue grades, which are produced entirely from waste paper. In addition, it will be possible to replace bright waste paper grades currently used with raw materials having lower ash content and further improve the water management of the deinking plant.
