In wastewater treatment plants, pipes, transfer lines, pumps, holding tanks, sedimentation tanks, aeration tanks, and related equipment are exposed to high concentration of aggressive sewer environments including organic/inorganic chemicals, solids, liquids, gases, and microorganisms. Each of these environments contributes to the corrosion and structural deterioration of concrete and metallic assets of the treatment plant. For example, sulfide is produced by anaerobic sulfur-reducing bacteria (SRB) from sulfates in the slime layer on the submerged sewer structures. It is then consumed by aerobic bacteria to produce sulfuric acid (H2SO4). These microbial metabolic products (H2S and H2SO4) have significant deteriorating effects on the plant assets. Other forms of corrosion, such as erosion and galvanic corrosion are also at work. Expert is familiar with all forms of Corrosion, including:
Uniform or general corrosion;
Localized corrosion (pitting);
Localized corrosion (crevice);
Galvanic corrosion;
Microbiological influenced corrosion (MIC);
Intergranular & transgranular cracking (IGC);
Velocity-related corrosion;
Sour corrosion;
Sulfuric acid corrosion;
Sweet corrosion;
Environmentally assisted cracking (EAC)
• Step wise cracking (SWC)
• Hydrogen-induced cracking (HIC)
• Hydrogen embrittlement (HE)
• Corrosion fatigue
• High pH Stress Corrosion Cracking (SCC)
• Near neutral pH SCC
Expert's engineering and forensic expertise in wastewater treatment facilities normally facillitate the development of comprehensive corrosion management strategy. This, in turn, aids judicious asset preservaton in terms of rehabilitation, retrofitting, and/or replacement based on feasibility of implementation, cost/benefit analysis, permanence/effectiveness of mitigation actions, etc.
