Mircrobiologically Induced Corrosion (MIC) is a biochemical process through which sulpher compunds present in wasterwater are transformed, through a complicated, multiple-step process, into sulphuric acid. This acid generation tales place directly over the surface, about the waterwater level, and can quickly lead to serious structural damage.
MIC takes place naturally over any waterwater facility where hydrogen sulphide is released from the wastewater. If the amount of hydrogen sulphide is small, the effects can be negligible throughout the entire designed lifespan of the sewer system, but under certain circumstances, MIC can also lead to critical structal damage in periods as short as four years.
