Corrosion In Wastewater Systems: More Than One Bug

concrete in wastewater systems has been recognized since 1945. Parker1 described the role of an acid producing bacterium that he called Thiobacillus concretivorous, which he had isolated from corroded concrete from a Melbourne, Australia sewage system. Th. concretivorous was described as a sulfate reducing bacterium (SRB)
