Application Scene
Water Treatment Field
- pH Adjusting Agent
Calcium hydroxide can effectively neutralize acidic water and adjust the pH value to the neutral range (pH 6.5-8.5), meeting the standards for drinking water and industrial water. - Coagulant Preparation
As a precursor of coagulant, calcium hydroxide promotes the sedimentation of suspended solids and improves water clarity. - Precipitation of Heavy Metal Ions
Calcium hydroxide reacts with heavy metal ions (e.g., lead, mercury) to form insoluble hydroxide precipitates, reducing water pollution. - Water Softening
Calcium hydroxide reacts with calcium and magnesium ions in water to form precipitates, effectively reducing water hardness, reducing scale formation, and improving the efficiency of industrial equipment and household water use. - ludge Treatment
Calcium hydroxide regulates sludge pH, promotes sludge dewatering and stabilization, reduces sludge volume, and lowers treatment costs and environmental impact.
