Scale Inhibition

The ability to prevent and control inorganic salts deposition is well understood. Specialty polymer technology provided by companies such as Noveon, Alco, Biolabs and Rohm and Haas provide hardness salts, iron, copper, phosphate, zinc and silica deposition control. This technology finds application in cooling water, boiler water , reverse osmosis and remediation systems.

Additionally inhibitors such as phosphonates, polyphosphates, and polymaleic anhydride provide additional inhibition of many divalent metal salts.

The control of LSI (Langelier Saturation Index) with pH adjustment is a traditional approach to prevent scale inhibition.
