What is Scale Inhibitor?
A chemical that prevents mineral scale deposition such as calcium carbonate, sulphate and silica on equipment surfaces in water systems.
View Chemical Dosing SystemsScale Inhibitor Explained
Scale inhibitors work by threshold inhibition, crystal modification and dispersion at dose rates of 2-15 mg/L. Selection depends on scale-forming ions present, operating temperature and system pH.
Common Applications
- Cooling tower scale control
- RO membrane antiscaling
- Boiler water treatment
- Heat exchanger protection
Important For
- Heat transfer efficiency
- Equipment life extension
- Reduced cleaning costs
Selection Factors
Correct selection depends on the process objective and site conditions. For Scale Inhibitor, Premix usually reviews these points before recommending equipment:
- Water analysis hardness sulphate silica
- Langelier Saturation Index
- System temperature
- Dose rate by calculation
Why It Matters In Plant Operation
Scale Inhibitor affects process stability, chemical usage, equipment life and final output quality. A correctly selected solution helps reduce trial-and-error at site and supports more predictable daily operation.
