Mirror Plating Wastewater Treatment
In the manufacturing of certain mirrors, a strong copper solution at low ph is used to apply a thin coating to the glass surface. After adhesion, the excess is washed off and collected as wastewater. The wastewater at this facility is treated using 4 chemicals: caustic to raise the pH to 8.5, DTC (dithiocarbamate) as a metal precipitant, an organic based coagulant, and an anionic flocculant. The ...
