Microbial corrosion is a type of corrosion caused by living organisms such as bacteria, algae, or fungi. This type of corrosion is often associated with tubercles or slimy organic materials.

In industries such as oil, gas and petrochemical, there is always an attempt to prevent the formation of deposits using different methods in equipment such as heat exchangers and boilers. In this field, a lot of money is spent on chemical materials and additives. But most industrial heat exchangers are exposed to sedimentation due to various reasons such as the low quality of water in different areas. These deposits are mostly formed in the pipes of the converters. In order to reduce the losses caused by sedimentation, the converter must be continuously monitored and cleaned.
