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.
