ATMP is widely used in applications including boiler water treatment, cooling water treatment, industrial and institutional cleaning, oilfield water treatment and general-purpose metal ion control.
ATMP is mostly used with organophosphoric acid, polycarboxylic acid and salt to form all organic water treatment formulation for various circulating cooling water systems with different water quality conditions. The amount of 1-20mg/L is preferred; in an amount of 20-60mg/L when used as corrosion inhibitor.
