AQUALIC™ Scale Inhibitor Offers Alternative to Conventional Phosphate Chemicals

Phosphate-based scale inhibitors are effective at reducing mineral deposits and scale buildup in water treatment systems, but they are increasingly facing regulations due to their environmental impact. To align with increasingly stringent sustainability requirements, several water treatment operations need environmentally friendly alternatives that don’t compromise performance. Although polyacrylate-acid inhibitors offer an alternative to phosphate inhibitors, they struggle to effectively reduce calcium phosphate buildup and require higher concentrations for impactful treatment.

Fortunately, most of Nippon Shokubai’s AQUALIC™ series of acrylic acid-based anionic polymers can be an alternative to phosphate inhibitors. Successful inhibitors to calcium phosphate, calcium carbonate and silicates, the AQUALIC series delivers excellent performance and is nonhazardous.

The AQUALIC Mechanism

These polymers, such as those made by Nippon Shokubai, disperse and stabilize scale via electrostatic repulsion.

Calcium Carbonate

As effective inhibitors of calcium carbonate, our YS-100 and TX-172 sodium polyacrylate products are versatile chemicals that achieve excellent performance as dispersants and chelators.

Magnesium Silicate and Calcium Phosphate

For calcium phosphate, GL-366 and GH-234 poly(carboxylate-sulfonate) are effective at reducing calcium phosphate buildup. The GB-65 polymer is good for magnesium silicate. GL-366, GH-234 and GB-65 even work under high salt level conditions.

Designed to meet the growing need for chemicals that match the performance of legacy scale inhibitors, the AQUALIC product line is stable and easy to handle. We offer AQUALIC as a non-hazardous aqueous solution with excellent storage stability. And we have a wide range of products with varying structures according to the usage purpose.
