Wirewater

Collecting the wirewaters (water that washes the forming wire) into a separate line for delivery to the treatment plant or to the whitewater tank as needed for makeup water.

Wherever possible, stocks tested were slush pulps (hardwood, softwood, recycled fibre and broke) before and after blending (ex concentrators, blend chest and machine chest), after chemical addition (filler, size, retention aid), thin stock(s) and wirewater(s).

On a multi-ply board machine, either on a multifourdrinier machine or on a multiple former machine, the wire waters are collected separately and the water circuits are usually separated.
