The evaporation is a thermal process that, starting from a solution, allows separating two liquid phases: a distillate and a concentrate.
The running principle consists in the evaporation of the waste water. The distilled water can be put again into the production cycle, while the concentrated pollutant can be disposed with remarkably reduced costs, considering the significant reduction of the volume.
- a strong reduction in disposal costs and sometimes the recovery of basic products
- get rid of the need to have an open circuit purification system allowing the almost total recovery of the washing water
- the recycled water, condensation, has a salinity lower than that of the raw water; this implies an improvement of some particular washings
