APPLICATION:
vibrofinshing wastewater of aluminium parts
DESCRIPTION:
A powder containing coagulating and flocculant agents is added to the waste water, which leads to the precipitation of pollutants in the form of sludge. Subsequently, there is a decantation phase from which a clarified product is obtained, which in turn is subjected to a vacuum evaporation test in order to obtain distilled water.
TECHNICAL DATA:
| PARAMETERS | PRE-TEST | CLARIFIED | DISTILLATE |
| pH | 7.2 | 7.3 | 6 |
| EC [µS/cm] | 516 | 567 | 3 |
| COD [mg/l O₂] | 39.3 | 6.3 |
HIGHLIGHTS:
- Recovery of a clear and colourless clarified product that can be reused in the processing cycle
- Formation of easily sedimentable sludge
- Vacuum evaporation at 30°C
- Recovery of 95% of the volume as distilled water
- Formation of a 5% volume concentrate, which appears as a pumpable liquid without bottom material.
