APPLICATION:
Double-effect vacuum evaporation of chemical-physical water treatment plant effluent.
DESCRIPTION:
A vacuum evaporation test is performed, divided into two stages with different vacuum degrees and temperatures, simulating a double-effect system. The test is performed to improve the characteristics of previously treated water to facilitate its direct recycling.
TECNICHAL DATA:
| PARAMETERS | PRE-TEST | CONDENSATE 1st Stage | CONDENSATE 2nd Stage |
| pH | 7,6 | 9,4 | 6,8 |
| EC [µS/cm] | 3969 | 134 | 20 |
| COD [mg/l O₂] | 208 | 127 | 173 |
HIGHLIGHTS:
- Recovery of 95% of the volume as clear, colorless water with low salt content;
- Formation of 5% liquid concentrate by volume, which is a pumpable;
- Treatment of large volumes of water with a single evaporator.
