APPLICATION:
Waste water from galvanic proccesses with high concentrations of metals in solution.
DESCRIPTION:
The wastewater is first subjected to a pH adjustment and the addition of a coagulating agent. A flocculation agent is then dosed and an alkaline pH is maintained to promote the formation of sludge. The sample is tested to verify the reduction of metals, specifically boron.
TECHNICAL DATA:
| PARAMETERS | PRE-TEST | POST-TEST |
