The new white liquor filter will replace an existing filter delivered by Valmet in 1990. A larger filter is needed to handle a capacity increase at the mill. Start-up of the new filter is scheduled for autumn 2016.
The Valmet delivery includes a new PDW-type white liquor filter, erection, start-up services, basic engineering for piping, for instrument and for electrical and process control.
The investment is part of Rottneros AB’s larger Agenda 500 rebuild project which aims to increase availability and the total production volume at its Rottneros and Vallvik pulp mills.
