FAQ About Scale Inhibitors
What are the main types of scale that scale inhibitors prevent?
Scale inhibitors primarily prevent calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate scales. These are the most common scales that form in industrial water systems, oilfield operations, and cooling towers.
How do scale inhibitors work at the molecular level?
Scale inhibitors function through three main mechanisms: threshold inhibition (preventing crystal growth at sub-stoichiometric concentrations), crystal distortion (changing crystal morphology), and dispersion (keeping particles suspended). Phosphonate-based scale inhibitors work by binding to active crystal growth sites.
What factors affect the performance of scale inhibitors?
Key factors include water chemistry (pH, hardness ions), temperature, pressure, system flow rates, and the presence of other treatment chemicals. Proper dosage is critical and should be determined through water analysis and system evaluation.
Application Guidelines
Our scale inhibitors can be applied in various systems:
- Cooling water systems: 2-10 ppm continuous feed
- Boiler water treatment: 1-5 ppm
- RO systems: 3-15 ppm
- Oilfield applications: 5-50 ppm depending on scaling potential
For optimal performance, scale inhibitors should be fed continuously where possible. Batch treatments may be used in some applications but require careful monitoring. Always conduct compatibility tests when combining with other water treatment chemicals.
