Retention influenced by Stock Flocculation

Retention – an important parameter for wet end chemistry

Retention aids are commonly used in the paper industry to influence the chemistry of pulp and final product quality. They are used to retain small particles and chemicals in the sheet rather than draining through the wire. Depending on paper grade, it is important to have the correct level of retention. Too low retention lets small particles and chemicals to drain through the sheet and accumulate in the white-water system. This causes several issues, such as deposits, poor runnability, increased usage of functional chemicals and sheet two sidedness.
