  • What is a corrosion inhibitor?
  • As a countermeasure, corrosion inhibitors are added to prolong the service life of piping throughout a water distribution system. Corrosion is a complex series of reactions between the water and metal surfaces (metal piping) and materials in which the water is stored or transported.
  • What are the different types of corrosion inhibitors?
  • They are normally classified as: anodic, cathodic, film-forming and oxygen-absorbing agents depending on their mode of action. The effectiveness of most corrosion inhibitors is significantly affected by the water’s chemical properties and by physical conditions such as temperature and flow velocity.
  • What are corrosion inhibitors & anodic inhibitors?
  • Corrosion inhibitors are often the most cost-effective way to prevent or control corrosion because they allow one to use less expensive metals for a corrosive environment. Anodic Inhibitors - They react with oxygen to form a thin film on the surface of the metal.
  • How to reduce corrosiveness of water?
  • Calcium-based compounds, soda and sodium polyphosphates can be added to reduce the water’s corrosiveness. The choice depends on the chemical analysis of the finished water. The corrosion inhibitor is added after filtration to avoid fouling.
