Hydroxy Ethylidene -1,1-Diphosphonic acid is organophosphonate with multifunctional properties like sequestration, deflocculation, threshold inhibition and hydrolytic stability, as a single active ingredient. Because of the combination of these properties Hydroxy Ethylidene -1,1-Diphosphonic acid has a wide range of applications. One of the most important applications is in scale prevention and corrosion inhibition in water treatment.
HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid. It is used as a strong chelating agent for metal ions like Ca, Mg & Fe in water treatment, textile applications. Its efficient inhibition for CaCO3 & CaSO4 alone or in combination with low molecular weight polymers. Very effective in protecting metal corrosion. HEDP also having very strong chlorine stability.

At high temperature of 250 Deg C HEDP also resulting good corrosion and antiscaling effect. <br />
<br />
It's good resistance towards High and Low pH value makes it unique and better than that of other organophosphoric acids (salt). HEDP also resulting high chlorine oxidation tolerance properties.<br />
<br />
HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. </div>
