FILTRATION PRODUCTS
Valmet Disc Filter CDI
Valmet Disc Filter CDI recovers fiber from white water while thickening broke or recycled pulp from medium to large flows. Its unique open rotor design enables the filter to seamlessly handle changes in feed consistency, flow and freeness.
Valmet Disc Filter CDP
Valmet Disc Filter CDP recovers fiber from white water while thickening broke or recycled pulp from low flows. Its unique open rotor design handles high feed consistency and freeness.
Valmet Disc Filter VDF
Valmet Disc Filter VDF can recover fiber from white water or thicken low-to-medium freeness pulp while producing high quality filtrate. When used as a thickener, it discharges at high consistency.
Valmet Ultrafiltration
Valmet’s Ultrafiltration process is a solution for paper, board and tissue mills to produce colloid-free, bacteria-free, ultrapure water from white water. The main objectives are to reduce fresh water consumption, improve paper machine runnability, efficiency, and manage energy.
Pressure-fed Bow Screen and Gravity-fed Bow Screen
Valmet Pressure-fed and Gravity-fed Bow Screens are curved inclined screens that separate liquids and solids. Valmet's industry-leading portfolio provides effective fiber recovery from tissue machine white water, efficient polishing of filtrate for shower water use and flexible thickening of low consistency stock streams, discharging at two (2) to five (5) percent consistency.
