Tri-Functional Synergy Under Extreme Stresses

Carboxylic acid groups offer strong calcium complexing; sulfonic acid groups deliver steric and electrostatic dispersion for iron/phosphate colloids; and non-ionic monomers resist salinity collapse even above 5,000 ppm TDS.

Ideal for zero-liquid discharge (ZLD) cooling tower operations running at 8 to 12 cycles of concentration and high skin temperatures.

Frequently Asked Questions: Acrylic Terpolymer

Expert technical answers on dosing, chemistry, handling, and application performance.

Q1. What is Acrylic Terpolymer (ZEELCHEM™ 7000) and what makes it tri-functional?

ZEELCHEM™ 7000 is a specialty tri-functional polymer incorporating carboxylic acid (for scale inhibition), sulfonic acid (for phosphate & iron dispersion), and non-ionic monomer groups (for steric stabilization) under extreme thermal, pH, and salinity stress.

Q2. What industrial systems require Acrylic Terpolymer treatment?

Zero Liquid Discharge (ZLD) cooling towers, all-organic corrosion/scale programs, geothermal steam reinjection, and high-recovery RO units with high silica and hardness.

Q3. What is the recommended dosage of Acrylic Terpolymer?

Continuous dosing of 10.0 to 25.0 ppm active in high-stress cooling towers, and 15.0 to 40.0 ppm in geothermal / heavy oil steam flood reinjection.
