Blind drilled, grooved, and suction drilled rolls are commonly used on presses in the papermaking process. The open areas in these rolls are designed to accept water from the fabric. It is important all the water in these rolls be evacuated before the nip to prevent re-wetting the sheet and to ensure optimum press nip performance. In some cases these rolls rely solely on centrifugal force to evacuate water, but this is often not sufficient, especially when the fabric becomes filled and cannot accept as much water.

Can Filtration Equipment Cost-effectively Reclaim White Water in Systems With a Variability in Solids?

Selecting filtration equipment that performs efficiently under the dynamic process conditions of paper machine white water loops can be a challenge for many papermakers. Variability in furnish, paper grades and the operating conditions of the machine, can lead to large swings in the type and amount of solids that must be removed from the white water before it can be reused in the process.
