Method of Precipitating Copper

During the last few years we have been doing considerable experimenting on methods of precipitating copper. The first patent on precipitating from sulphate solutions by heating with SO2 under pressure was taken out by us (U. S. Pat. 723,949). This reaction, CuSO4 + SO2 + 2H2O = Cu + 2H2SO4, is interesting, but there are a number of practical difficulties which will be met with in carrying it

Copper Removal at the Gardner Wastewater Treatment

The final clarifier had higher dissolved copper levels in 5 of the 6 trials conducted. These higher values can be explained by the reactions taking place in the activated sludge tanks. The results show that dissolved copper is less of a problem and harder to filter than total copper, so total copper is the primary target for removal in the WWTF.
