ATMP is a phosphonate widely used in treating cooling or boiler water systems as scale and corrosion inhibitor. Many of water treatment chemical formulations contain ATMP as an important ingredient due to following advantages:Multifunctional performance from a single raw material Superior cost/performance in scale inhibitionSynergistic performance from formulated mixturesReplacement of sequestration levels of other chelants with threshold levels of phosphonateUsed in oil field as Antiscale dispersant.
