Description
Genome Specialities supplies high-quality Hydrated Lime, also known as Calcium Hydroxide, Slaked Lime, or Builders’ Lime.
A fine, white, inorganic powder with strong alkaline properties and is widely used across construction, water treatment, agriculture, environmental management, and industrial processes.
produced from quicklime through a controlled hydration process.
Its high alkalinity and ability to neutralize acids make it a versatile material for a wide range of commercial and industrial applications

Uses Of Hydrated Lime
Construction:
This is one of the most significant uses of hydrated lime.
used in soil stabilization for roads and building foundations to improve the soil’s load-bearing capacity.
Water and Wastewater Treatment:
used to adjust the pH of water, soften it by removing hardness ions (calcium and magnesium), and as a flocculant to help remove suspended solids and impurities.
Flue Gas Treatment:
used to neutralize acidic gases, such as sulfur dioxide, from exhaust streams, reducing air pollution.
Agriculture:
Soil Amendment: Farmers use hydrated lime to reduce soil acidity, or “sweeten” the soil. This raises the pH, which improves nutrient availability for plants, leading to healthier crops and increased yields.
Disinfection:
used to disinfect animal bedding in barns and poultry houses.
Industrial Processes:
Steel Manufacturing:
used to remove impurities from steel in the refining process.
Chemical Manufacturing:
It serves as an alkali source in the production of various chemicals, including calcium salts.
Sugar Refining:
Used to purify sugar cane juice by precipitating out impurities.
