Typical Applications of Hydrated Lime:
- Municipal water and wastewater treatment
- Industrial wastewater treatment
- Soil pH correction
Hydrated lime is the common name for calcium hydroxide. In water, it is a source of free hydroxide ions that can neutralize acidity and raise the pH of a solution. Adding hydrated lime to water can also increase or maintain the sample’s alkalinity. Sufficient alkalinity is required for coagulation and is therefore an important factor to control.
