METHOD AND APPARATUS FOR HANDLING WHITE WATER IN A TWIN-WIRE MACHINE Abstract of the Disclosure In order to produce a reduction in the content of suspended matter in the surplus white water in a twin-wire machine with a curved forming zone, an outer saveall for collecting white water thrown outwardly from the curved forming zone is divided up into at least two separate saveall compartments arranged after each other in the direc- tion of travel of the wires. The white water that is caught in the first saveall compartment in the direction of travel is returned to the twin-wire machine as diluting water by a short circulation, while white water from a succeeding saveall compartment has a lower content of suspended matter and is removed from the actual papermaking process as surplus white water, and can be conducted, for example, to a grinder room for use there as shower water.
