MICRO ORGANISMS CORROSION M016
These organisms are commonly used in sewage treatment, oil spills and other cleaning processes.
Although there are many different uses for these “bugs” a common one is for them to eat the carbon you find in waste and other hydrocarbons and convert it to carbon dioxide. The “bugs” fall into three categories:
- Aerobic, the kind that need oxygen.
- Anaerobic, the kind that do not need oxygen.
- Facultative, the type that goes both ways. They operate with or without oxygen
If the protective oxide layer is removed from stainless steel because of rubbing or damage the “bugs” can penetrate through the damaged area and attack the carbon in the metal.
Once in, the attack can continue on in a manner similar to that which happens when rust starts to spread under the paint on an automobile.
