Applications of Hydrated Lime in Water Treatment
Clean and safe water is essential for life, industry, and the environment. Among the many materials used in water treatment, hydrated lime stands out for its efficiency, affordability, and versatility. As demand for high-quality water grows, especially in Rajasthan, the role of hydrated lime manufacturers in Jodhpur becomes increasingly important.
This blog delves into the key applications of hydrated lime in water treatment and highlights why Jodhpur is emerging as a major hub for lime supply in India.
What is Hydrated Lime?
Hydrated lime, chemically known as calcium hydroxide (Ca(OH)₂), is a white, dry powder obtained by adding water to quicklime. It is widely used in water treatment due to its strong alkaline properties and ability to neutralize acidic contaminants.
Why Hydrated Lime is Used in Water Treatment
Hydrated lime plays a vital role in water purification and treatment processes, both in industrial and municipal settings. Here’s how:
1. pH Adjustment
Hydrated lime effectively increases water pH, reducing acidity and making the water less corrosive to pipelines and equipment.
2. Softening Hard Water
It helps remove hardness caused by calcium and magnesium salts, reducing scaling in industrial systems and household plumbing.
3. Coagulation and Flocculation
Hydrated lime enhances the coagulation process by forming larger flocs from suspended particles, which can then be easily filtered or settled out.
4. Neutralizing Industrial Wastewater
Industries such as steel, textiles, chemicals, and pharmaceuticals use hydrated lime to neutralize acidic effluents before releasing water into the environment.
5. Removal of Heavy Metals
Lime precipitates heavy metals like lead, zinc, and cadmium from water, making it safer for human use and less toxic for aquatic life.
6. Disinfection Aid
When used alongside chlorine, hydrated lime boosts the effectiveness of disinfection by increasing the pH, which can destroy certain pathogens more efficiently.
7. Algae Control in Reservoirs
By stabilizing pH levels and binding nutrients like phosphorus, hydrated lime helps limit algae growth in water bodies.
Key Sectors Using Hydrated Lime for Water Treatment
Municipal Corporations: For drinking water and sewage treatment.
Textile and Dyeing Plants: To treat dye-laden acidic wastewater.
Pharmaceuticals: For pH balancing and neutralizing reactive waste.
Steel Plants & Metal Industries: For removing heavy metals.
Food Processing Units: For treating organic waste and maintaining hygiene.
