PT Retention
Optimized Retention – Increased Productivity
1. Optimum usage of raw materials
2. Few material losses to the clarified water
3. Reduced waste water load
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.
Too high usage of retention aids may cause bad formation and runnability issues. Ideal retention allows water to drain through the sheet while retaining the paper machine chemicals and producing a consistent product. This reduces the steam required to dry the sheet in the dryer section and allows the machine to run faster.
Reliable in- and online instrumentation combined with our market leading wet end expertise help our customers to run their machines in optimum operation window, producing more in spec tons 24/7.
