Abstract
The purpose of this study was to evaluate the toxic effects of Cu(II) on a chemostat containing activated sludge. Different concentrations of Cu(II) (0.5, 1.0, 5.0, and 10.0mgL‐1) were maintained in a laboratory‐scale completely mixed activated sludge unit, without recycle, treating simulated wastewater. The feed solution contained 650 mgL‐1 protein (corresponding to 1300 mgL‐1 COD) as a source of carbon. Experimental results indicated that the treatment efficiency was not adversely effected by the presence of Cu(II) up to the concentration of 10.0 mgL‐1. Moreover, some stimulatory effects of Cu(II) on the biokinetic parameters were observed.Keywords
