The following bacteriia types are identified in the water and/or deposit test. An approximate population for each is included in the report.
Acid Producing Bacteria
Chemical corrosion is a major player in the MIC corrosion Process.
APB Are capable of producing inorganic & organic acids (which corrode the iron) as well as providing nutrients for sulfate reducing bacteria (SRB). They contribute to pitting & pin-hole leaks.
Sulfate Reducing Bacteria
SRB are probably the most destructive group of the MIC bacteria as they are a primary cause of pitting & pin-hole leaks.
They mine iron from the pipe, take sulfur from the water & produce iron sulfide (black solids) & hydrogen sulfide gas (rotten egg smell).
Iron Related Bacteria
IRB are iron utilizing. They build tubercles & are responsible for the destructive corrosive process in iron & steel. They cause pitting & pin-hole leaks.
IRBs are known to have a symbiotic relationship with other groups of MIC bacteria.
Slime Forming Bacteria
Slime forming bacteria live in conjunction with APB, SRB & IRB.
They are an important part of the MIC process, often acting as the transient from aerobic to anaerobic conditions & as a support system for the corrosion process.
