The future generation of paper machines will be characterized by increased operating speeds and at the same time higher product quality demands, including machine directional (MD) and cross machine directional (CD) profile stability. To meet these new requirements, the wet end process (WEP) around the wet end of the paper machine needs to be redesigned. New machines and tools are presented here for mixing the stock and filler components, for whitewater dilution, deaeration, adding of retention agents and for the entire whitewater handling. The overall goal is to optimize the entire WEP for more profitable operation.
