DEMO D: Printed Circuit Board / AT&S – Fehring, Austria
What‘s it about:
Recovery of fresh water and gold from the PCB production by applying Membrane Distillation.
Key Performance Indicators
Manufacturing capacity: 250.000 m² PCB per year.
Problem definition:
• Variation in bath concentration during the operation
• Loss of precious metals like gold and palladium.
Waste water streams: 100.000 m³ of waste water/a.
Advantages: Circular economy approach – no waste; recovery of valuable resources; Use of waste heat; Reduction of operating costs; Reduction of environmental pollution,
Increase of company profit.
Validated models will be used for future scenarios analysis and planning.
Actual Results: Signifi cant reduction of gold loss
