Hydrodynamic Web Formation Processes

Hydrodynamic web formation is derived from the simple and very wet paper-production process. In principle, it is a filtration of a fiber suspension by means of a rotating sieve. To reach an even web, the fibers have to be constantly suspended and dispersed in water. The transport of fibers to the web-forming zone must not lead to a disorganized fiber distribution in the suspension. 

The water moves in a cycle to reduce the water consumption of a wet weh plant. Only the water that is carried out of the plant with the web has to be replaced. The water industry has to recognize and satisfy these high demands. Because the web-forming process itself filters the water, filtration is not necessary. 

Further requirements are a perfect distribution of the fibers in the suspension. The mixer speed, the line cross section, and the pump parameters have to be adjusted to it.
