Corrosion Protection, Maintenance and Economic Considerations for Wastewater Treatment Plant Equipment
Wastewater treatment plants process and handle some of the most corrosive solids and liquids in process engineering, often suffering damage after prolonged operation to pipes, tanks, pumps and electrical conduit systems, among others. Even instrumentation panels or meters that measure flow, level, pressure, temperature and other parameters conducive to proper facilitation are subjected to corrosion and gas exposures, causing substantial, expensive damage.
Structure owners and users are becoming increasingly aware of the liabilities and the costs of corrosion. Carrying out remedial work—particularly on highway structures, bridges and tunnels—has led to a renewed interest in the use of stainless steel reinforcement to minimize the risk of corrosion to structures exposed to marine/coastal environments, road deicing salts, chlorides and other harsh elements.
