Thickening, clarification and washing
In challenging recycled fiber processes, reliable liquid clarification and thickening is critical for maintaining continuous and cost-effective operation. The aim of an efficient thickening and clarification system is to cost-effectively sustain a high production rate.
Washing improves paper machine runnability, when recycled fibers are cleaned of sticky material, non-usable fines and ash. Valmet washing process features high unit capacity and washing efficiency.
Disc filtering
Valmet’s disc filter improves efficiency and reliability while simplifying maintenance and service procedures.
Screw pressing
Screw presses are suitable for thickening a wide range of pulps. The design of the press is based on extensive experience of multiple applications in pulp and paper production and other industries.
Ultrafiltration
Valmet’s Ultrafiltration process is a solution for paper, board and tissue mills in producing colloidal, bacteria-free, ultrapure water from white water.
Washing
he effective ash and fines removal provides many advantages compared with existing conventional washing technologies.
