Phosphonates are multi-functional metal ion control agents. The unique combination of properties found in phosphonates makes them well suited to address many of the problems encountered in the use of water. Thus, they have become a widely used component in water treatment formulations. In recent years they have also found their way into numerous other applications where metal ion control is crucial to a product or process, such as detergents, cleaners, peroxide stabilization, oil field, swimming pools and spas, and many others.
Industries and applications using phosphonates for scale control include Cooling water, Boiler water, Detergents and cleaners, Oil field, Pulp and paper, Reverse osmosis, and Swimming pools.
