Cost of wastewater treatment for acid copper plating


(1996)

Hi to all,

I am looking for some information on the cost of wastewater treatment for an acid copper electrolytic plating operation.

Can someone tell me how much % does this represent in the overall cost of a board manufacturing or how much per pounds of plated copper for other applications?

Also, can someone tell me how much of the total treatment costs are driven by the additives in these electrolytic plating solutions.

Thanks!

The SFMRB reports available from AESF or NAMF (www.nasf.org) should have some industry averages on treatment costs, Denis, although all such statistics are partially a fiction.

I am not aware of any special treatment and consequently any extra treatment costs to deal with the additives in a plating bath. But the cost of treating an acid vs. a cyanide vs. a pyrophosphate bath might vary.

Regards,
