Process and plant for washing without waste water discharges. The washing is done with recycling wash water, which is continuously purified and regenerated between each use. The rinsing is done in at least two stages. The wash water and the rinse water are recycled in two separate circuits balanced against each other in such a way that the water additions to the system may be limited to correspond to the losses through withdraw. In this way the plant can operate without generating surplus of wash water that must be discharged to the sewage system. |
