Cast Iron/Steel Corrosion

Corrosion can be prevented by allowing a thin phosphate film to form on metal surfaces to act as a protective barrier coating. This minimizes the amount of corrosive oxygen at the metal surface. The film formed must be maintained by feeding the inhibitor at low treatment levels on a continuous basis. A blend of polyphosphates and orthophosphates maximize the anodic and cathodic corrosion protection.

Lead Corrosion

Lead in drinking water is generally caused by the corrosion of distribution materials in the system. Generally, the lead is leached into the system, as opposed to being produced by the well or surface water source. The United States EPA is developing MCL's (Maximum Contaminant Levels) at the 5 to 20 ppb level and requiring samples to be taken on a "first draw" basis. A great majority of the public water systems in the United States will be required to take preventative treatment measures.

Water Solutions Unlimited has inhibitors designed to form a protective film to minimize the leaching of soluble and insoluble lead by-products.

WSU will be continually developing and testing new inhibitor formulations to assist its customers in meeting EPA requirements. Look for Water Solutions Unlimited to be a leader in this technology.

Copper Corrosion

Copper in drinking water is usually the result of aggressive water conditions of low pH and high chlorination levels in the distribution system. Water Solutions Unlimited personnel can test water at the point of entry, measure water quality and test the distribution water. From this data, a treatment recommendation can be made including the use of WSU inhibitors. Most importantly, a recommendation can be made to measure the results.
