- the temperature of the water flowing downwards in the evaporator 10 drops from head to toe as heat is removed from the water by evaporation and heat transfer to the countercurrent air. Accordingly, the temperature of the countercurrent air from the foot to the head of the evaporation device 10 increases. The temperature of the air remains in stable operation with stationary conditions but always below the water temperature at the same height of the Verduns- device 10. In the evaporation device 10 thus takes place a heat transfer from the falling water to the rising air. Due to its rising temperature, the air can absorb more water vapor. So water and air form a countercurrent heat exchanger.
- the concentrated water is cooled after passage of the Verduns ⁇ processing device 9 and fed to a template tank, not shown. Cooling is possible even after such a storage tank. In such a storage tank, a pH adjustment could be made. To prevent too high concentration, some of the concentrated water can be replaced by fresh raw water.
- the heat output to be dissipated by cooling is equal to the heat output minus the power required for demixing (entropy change). It is a particularly efficient process in terms of energy.
