ANDRITZ SelectaFlot flotation unit Metsä Tissue opted for installation of an ANDRITZ SelectaFlot flotation unit (pictured above) to improve brightness and remove ink particles at low fiber loss and energy consumption.

Feb. 12, 2018 - ANDRITZ has received an order from Metsä Tissue to modernize and upgrade the existing deinked pulp (DIP) line at the Metsä Tissue mill in Mänttä, Finland.

The new DIP line is to supply the furnish for all three tissue machines at the Mänttä mill and will process medium- to high-quality recycled paper grades to be used as raw material for production of various tissue products.

ANDRITZ will upgrade the pulping process with a new detrashing system — comprising a FibreGuard Detrasher, a FibreWash Drum, and a Detrashing Pump — to increase pulp quality through early removal of non-disintegrated reject materials.

In the three-stage coarse screening process, three new screens — type ModuScreen F and TC — with the latest slotted screen baskets and an AhlCleaner RB will be installed to ensure efficient removal of coarse contaminants at minimum fiber loss.

An ANDRITZ SpeedWasher will separate inorganic material, such as filler and coating pigments, from the fiber suspension to enable low ash content at the end of the line. An ANDRITZ Pulp Screw Press further dewaters pulp that is suitable for subsequent dispersing.

In order to meet the high quality requirements of certain tissue products, Metsä Tissue opted for installation of an ANDRITZ SelectaFlot flotation unit to improve brightness and remove ink particles at low fiber loss and energy consumption.

Basic engineering, dismantling of the existing equipment, erection, commissioning, start-up, and training will likewise be supplied by ANDRITZ to minimize the shutdown period.
