Water Treatment Applications
1. Water Quality Softening
Reacts with calcium and magnesium ions in water to generate insoluble precipitation, thus softening water quality.
Reaction equation: 3Ca²⁺ + 2PO₄³⁻ → Ca₃(PO₄)₂↓
2. Scale Prevention
By chelating calcium and magnesium ions, prevents scale formation in boilers and pipes. Widely used in boiler water treatment and cooling water systems.
3. Corrosion Inhibition
Forms protective film on metal surfaces to prevent corrosion. Used in boilers, heat exchangers and cooling water systems.
4. pH Adjustment
As an alkaline substance, regulates water pH. Used in industrial wastewater and swimming pool water treatment.
5. Dispersant
Disperses suspended particles to prevent deposition. Used in circulating cooling water systems.
6. Microbial Control
Inhibits microorganism growth by increasing water pH. Used in drinking water and industrial water treatment.
7. Other Applications
- Flocculant: Helps remove suspended solids
- Cleaning agent: Removes sediment and dirt from water treatment equipment
