Sulfur-reducing bacteria in the effluent degrades the organic matter, forming hydrogen sulfide (H2S) as a waste product. The hydrogen sulfide gas is oxidized by sulfur-oxidizing bacteria to form biogenic sulfuric acid. This lowers the pH level on the surface of the concrete, enhancing the spread of sulfur-oxidizing, acid-producing bacteria.
