Dewatering Problems (Troubleshooting Guide)

Dewatering (Too Slow, Too Fast) The most common problems related to dewatering involve slow or variable drainage and response to vacuum. Slow dewatering may involve "slow initial drainage" on the forming table, low solids after vacuum application, low solids after wet-pressing, or just a consequent lower operating speed of the paper machine.
