Cooling Water Chemistry – Open Loop Scale Prevention – CaCO3

Scale and corrosion prevention are at the heart of all cooling programs.
Sustainable Water Solutions believes in open communication and full data transparency. SWS LLC uses the following base building blocks in many of our open cooling formulations. The specific formulation is dependent on your unique application.

For Calcium Carbonate Control SWS LLC uses base building blocks in formulations:

HEDP
HEDP is an organophosphoric acid corrosion / scale inhibitor.
HEDP can chelate with Fe, Cu, and Zn ions to form stable chelating compounds.
HEDP shows excellent scale and corrosion inhibition effects under temperature 250℃.
HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions.
HEDP acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt).
HEDP can react with metal ions in water systems to form hexa-element chelating complex, with calcium ion in particular. HEDP is an aqueous solution of Hydroxyethylidene-diphosphonic acid (HEDP). It provides control of calcium and other metal salts including iron and manganese by acting as a strong crystal modifying agent and threshold inhibitor. HEDP is known to be a sequestrant and excellent deposit control agent.

AMP / ATMP
AMP is an aqueous solution of aminotris (methylene phosphonic acid), AMP.
AMP provides control of calcium and other metal salts including iron and manganese by acting as a crystal modifying agent and threshold inhibition.
AMP is know to be a sequestrant and deposit control agent due to its dispersing and deflocculating characteristics.
AMP is widely used as a scale and corrosion inhibitor in treating cooling water systems. Many water treatment chemical formulations contain ATMP as an important ingredient due to its multifunctional performance from a single raw material, superior cost/performance in scale inhibition and synergistic performance in formulated mixtures

PBTC
PBTC acts as a crystal modifying agent and threshold inhibitor for calcium and other metal salts.
PBTC is an active aqueous solution of 2-phosphonobutane-1, 2, 4-tricarboxylic acid.
PBTC acts as a crystal modifying agent and threshold inhibitor for calcium and other metal salts.
PBTC is widely used in industry as a sequestering agent and calcium carbonate scale inhibitor.
In systems that utilize oxidizing microbiocides, such as chlorine and bromine, PBTC exhibits superior stability under oxidizing conditions compared to other organophosphonate compounds.
PBTC is widely used in industry as a sequestering agent and calcium carbonate scale inhibitor.

Process Design Review. Before any recommendation is made for product a full process design review is conducted to assure the current operation is optimal.

Optimization of Current Process. Current process chemistry, recovery, rejection, pressure, and cleaning practices are reviewed.
