What are the differences between HEDP and ATMP in terms of scale inhibition performance?
Both HEDP (1-Hydroxyethylidene-1,1-diphosphonic acid) and ATMP (Amino trimethylene phosphonic acid) are organophosphonate scale inhibitors commonly used in industrial water treatment, including boilers, cooling towers, and desalination. They work primarily through threshold inhibition (preventing crystal nucleation/growth at sub-stoichiometric doses), lattice distortion (making scale crystals less adherent), and chelation of scale-forming ions like Ca²⁺ and Mg²⁺. Their…
