What Advantages can Potable Corrosion Inhibitors Offer Over a Calcium Carbonate Stability (Langalier) Program?

• Sequesters Calcium and Magnesium; inhibits scale formation both through sequestering and crystal modification.

• Sequesters iron and manganese, eliminates “red” and “black” water and the stains and complaints associated with them.

• Provides better passivation of all metallurgies, reducing corrosion rates on iron, copper, and brass.

• Passivates lead and copper; promotes the formation of a stable lead compound, hydroxypyromorphite – one of the most stable forms of lead.

• Provides cleaner distribution systems - helps remove bio-films and old corrosion products that have accumulated.

• Can reduce chlorine demand if applied correctly by removing the metals as part of the chlorine demand.

• Can be very cost effective to use if all the benefits are included in the analysis.
