Effects of Heavy Metals on the Characteristics of Microorganisms in Activated Sludge: A Review

Abstract:

Nickel (Ni (II)), cobalt (Co (II)) and manganese (Mn (II)) are often encountered in wastewaters. These metals have been identified as micronutrients, at trace concentrations; however, they are microbial growth inhibitors, at relatively high concentrations. The present review discusses, in a systematic way, the individual effects of the above heavy metals to the growth of microorganisms grown under aerobic conditions, with focus on the growth of activated sludge.
