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.

The Causes of Flooding in Paper Dryers
The majority of flooding incidents can be attributed to steam and condensate system issues (poor equipment sizing, incorrect system set-points and incorrect system calibration) and mechanical issues (unreliable or incorrectly installed steam joints and syphons). In this discussion, we will focus on the steam system issues that contribute to flooding.
