Definitions
- the collected white water contains relatively much air, which is why it is reduced in a degassing device 15 to a content of free air of less than 1% by volume.
- the high-consistency 1 and the low-consistency stream 2 are passed via at least one pump each.
- the already prediluted high consistency stream 1 is combined with the low consistency stream 2.
- the low-consistency stream 2 is fed into a low-consistency flow cross-distributor and the high-consistency stream 1 into a high-consistency flow cross-distributor of the headbox 12.
