most wastewater facilities include acidic wastewater, hydrogen sulfide, and sulfuric acid. The most severe deterioration from these corrosives occurs on the exposed wall and slab underside surfaces at and above the flow line in enclosed or covered spaces. In these spaces, dissolved sulfides are released from turbulent wastewater as hydrogen sulfide.
