Microbiologically influenced corrosion (MIC) activity in wastewater treatment plants is discussed. Three case histories are presented showing through-wall pitting from MIC in return activated sludge (RAS) process piping systems. Field and laboratory investigation activities are reported. Alternatives are reviewed for initial corrosion prevention and mitigation following identification. A brief discussion of wastewater treatment and specifically, the activated sludge process is also provided. The applicability of common MIC prevention and mitigation practices to wastewater treatment facilities or processes is also reviewed.
