The single module pipes of the plant are equipped with a large number of membranes which do the separation of the water and the reconcentrating of the sizing agent.
A number of serial ultrafiltration modules form a module stage or a stage of the plant.
The flow schematic below shows the circuit of size and water during recycling.
The picture shows the processes of sizing, weaving and desizing in a schematical way.
The washing liquor from desizing is brought to the recovery plant instead of going into the drain.
In the recovery system the size liquor is reconcentrated by separating water through membranes.
The separated water goes back to the washing process and the reconcentrated size liquor is brought back to the sizing machine for reuse.
