Corrosion Protection, Maintenance & 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. A wastewater treatment plant is a complex, sophisticated system with a high level of standards for the entire plant, including technical installations. The materials needed to construct a WWTP must be able to withstand a wide range of corrosive conditions.
