Filtration

Smart filtration ensures lower fresh water consumption and reduces chemical consumption
OptiDewater Disc – New technology and design improves performance, capacity and reliability
Valmet’s OptiDewater Disc improves efficiency and reliability while simplifying maintenance and service procedures. Several design features secure the disc filter’s increased capacity. Good flow characteristics – the result of shaft design, optimum internal volumes and filtrate valve selection – give the OptiDewater Disc better cake formation and filtrate quality while offering increased capacity compared to other similarly sized disc filters.
Ultrafiltration – A modular process for paper machine white water treatment
Valmet’s Ultrafiltration process is a solution for paper, board and tissue mills in producing colloidal, bacteria-free, ultrapure water from white water. The main objectives are to reduce fresh water consumption, improve paper machine runnability and production efficiency, and control energy balance.
