APPLICATION:
Vacuum evaporation of wastewater containing penetrant liquid.
DESCRIPTION:
The test is performed on wastewater from the washing of parts on which penetrant liquid had been previously applied. The sample was subjected to a vacuum evaporation test in order to verify the percentage of recoverable distilled water and the characteristics of the concentrate.

|
PRE-TEST | DISTILLATE |
| pH | 6,6 | 6 |
| EC | 270 µS/cm (20°C) | < 10 µS/cm (20°C) |
| COD | 11 mg/l O₂ |
HIGHLIGHTS:
- Evaporation under vacuum at 35°C
- Recovery of 90% of the volume as distilled water
- Formation of a concentrate at 10% of the volume, which appears as a pumpable liquid without bottom body and not encrusting
