MIC Information: Bacteria
There are many kinds of bacteria that cause Microbiologically Influenced Corrosion.
Need oxygen to function.
Do not need oxygen to function.
|Aerobic Bacteria |
Thiobacillius Thioxidans: Produce Sulfuric Acid.
Thiobacillis Ferrooxidans: Oxidize Ferrous to Ferric.
Gallionella & Sphaerotilus: Oxidize Ferrous to Ferric. Form Tubercles.
Pseudomonas: Can Reduce Ferric to Ferrous.
Fungi: Some Can Produce Organic Acids.
Desulfovibro: Promotes formation of Sulfide films. Affects Iron & Steel, Stainless Steels, Aluminum, Zinc & Copper Alloys.
Desulfotomaculum: Produces Hydrogen Sulfide Gas. Affects Iron & Steel, and Stainless Steels. Spore Former.
Desulfomonas: Produces Hydrogen Sulfide gas. Affects Iron & Steel.
What does it matter if they are Aerobic or Anaerobic?
Different bacteria can thrive in different parts of your fire sprinkler system and cause damage by the MIC process.
Dry Systems: Mainly aerobic conditions.
Wet Systems: Mainly anaerobic conditions.
Both Systems May Have Micro-Environments where both aerobic & anaerobic conditions exist.
