This paper presents a study on the effects of Cu (2+), Zn (2+) and Ni (2+) in activated sludge, focussing on their influence in COD removal efficiency. Experiments have been done at different heavy metals-concentrations varying from 1 to 25 mg/1. Cu (2+) exhibits the higher detrimental effect, followed by - Zn (2+) and Ni (2+). Mixtures of these heavy metals show a less than additive effect.
