Industrial & Commercial Applications
Water Treatment
Acts as scale inhibitor in cooling towers (dosage: 2-10 ppm), prevents CaCO₃/CaSO₄ deposition. Compatible with chlorine up to 5 mg/L.
Oilfield Applications
Used in hydraulic fracturing fluids at 0.1-0.5% concentration to control iron sulfide scaling.
Pulp & Paper
Chelates metal ions in bleaching processes (0.05-0.2% addition), improves H₂O₂ efficiency by 15-20%.
Implementation Case Studies
Case 1: Power Plant Cooling System
Challenge: 40% efficiency loss from scaling in 500MW coal plant
