Fighting Corrosion in Wastewater Treatment Plants

摘要

Constant moisture and contaminants at a wastewater treatment plant create highly corrosive conditions that attack metal and concrete structures, causing deterioration and forcing early repair or expensive replacement. Even corrosion resistant metals such as aluminum and galvanized steel become casualties of the harsh elements flowing through a wastewater plant. Conditions are worse still when the treatment plant is located in a humid coastal environment exposed to salt spray. Continued oversight and preventive maintenance is critical to minimizing corrosion and maximizing the longest service life possible for costly plant assets.
