TL;DR: Hydrated lime is calcium hydroxide, Ca(OH)2, produced by slaking quick lime with controlled quantities of water. Water treatment plants and effluent treatment plants (ETP) use it for acid neutralization, pH correction, heavy metal precipitation and sludge conditioning. Chemical & Mineral Industries Private Limited (CMIPL), founded in 1967 in Jodhpur, Rajasthan, manufactures and exports hydrated lime, quick lime and calcium carbonate, operating three lime kilns with a combined production capacity of 1200 TPD.

What Is the Use of Hydrated Lime?

Hydrated lime is an alkaline mineral compound used across municipal utilities, heavy processing industries and environmental treatment facilities. When calcium oxide undergoes controlled hydration, it forms a fine, dry powder suitable for liquid dosing, slurry preparation and chemical reaction circuits.

Industrial plants rely on hydrated lime because it dissolves into alkaline slurries that stabilize solution chemistry without introducing volatile organic byproducts. It provides rapid acid neutralization and precipitates dissolved sulfates, heavy metals and fluorides. Chemical manufacturers use it as a reactant in bleaching powder synthesis and other processes, and in flue gas treatment, dry hydrated lime powder is injected into exhaust ducts to capture sulfur dioxide, hydrogen chloride and acid mist. Because it combines predictable basicity with simple dry pneumatic handling, hydrated lime is deployed wherever continuous chemical neutralization is required.

Hydrated Lime for Water Treatment and Effluent Applications

Industrial wastewater and zero liquid discharge (ZLD) effluent treatment plants handle variable inlet acidity, dissolved metals and fluctuating loads. Hydrated lime for water treatment serves as a primary conditioning agent for pH adjustment, coagulation and sludge stabilization. Dosing slaked lime into acidic wastewater neutralizes free mineral acids and raises the pH to the range where metal hydroxides precipitate and settle.

In ZLD circuits, hydrated lime helps precipitate insoluble salts, fluorides and phosphates, clarifying overflow and easing the load on downstream reverse osmosis membranes. Calcium ions also support coagulation by compressing colloidal double layers, promoting dense floc formation. In municipal potable water networks, operators dose hydrated lime to stabilize soft, aggressive water and prevent pipeline corrosion. During sludge conditioning, lime dosing accelerates mechanical dewatering in filter presses and reduces odor. Because ETP installations depend on uninterrupted dosing, sourcing consistent calcium hydroxide from an established kiln operator helps plant supervisors keep neutralization tanks steady and avoid compliance upsets.

High Purity Hydrated Lime Manufacturers India

Selecting high purity hydrated lime manufacturers in India means evaluating raw material quality, calcination technology and processing standards. Hydrated lime performance depends on the purity of the limestone and on how well the parent quick lime is calcined. Insufficient calcination or poor slaking control can leave unreacted cores and inert grit that settle in mixing vessels, wear dosing pumps and plug slurry lines.

CMIPL manufactures and exports industrial minerals, specializing in calcium carbonate, quick lime and hydrated lime. The company was established in 1967 by Shri Vimal Raj Singhvi and spearheaded by Shri Kewal Raj Singhvi. CMIPL became the first PCC ISO 9001:2008 company, is ZED Certified by the Ministry of MSME of India, and was selected among the Top 100 SMEs of India in 2022 from 37,134 nominations.

Hydrated Lime Rajasthan Manufacturing Infrastructure

Rajasthan's high-calcium limestone belts provide raw stone suited to calcination into reactive quick lime (CaO) and conversion into hydrated lime. CMIPL's manufacturing base in Boranada, Jodhpur, is built to support continuous bulk mineral demand across India.

CMIPL operates three lime kilns with a combined production capacity of 1200 TPD. In 2014, CMIPL commissioned India's first pet-coke fired Twin-D lime kiln of 300 TPD, engineered by Cimprogetti S.P.A., at Boranada, recognized by the Limca Book of Records in 2016. The second kiln followed within five years, and the third was commissioned in 2023. 100% of the CO2 emissions generated during calcination are reused in PCC manufacturing, and company-owned windmills in Jaisalmer and Barmer provide 1.4 MW of renewable power.

What's the Difference Between Hydrated Lime and Agricultural Lime?

Hydrated lime and agricultural lime differ in chemistry, reactivity and use:

• Chemical identity: hydrated lime is calcium hydroxide, Ca(OH)2; agricultural lime is calcium carbonate, CaCO3 (or dolomite).

• Manufacturing: hydrated lime is slaked from calcined quick lime; agricultural lime is quarried stone pulverized without kiln calcination.

• Neutralization speed: hydrated lime reacts immediately; agricultural lime dissolves slowly over months.

• Alkalinity: hydrated lime is strongly alkaline; agricultural lime is mildly basic.

• Main uses: hydrated lime for water treatment, ETP neutralization and flue gas scrubbing; agricultural lime for soil conditioning.

• Handling: hydrated lime needs dry storage and dust management; agricultural lime is stable and non-reactive with ambient air.

Because hydrated lime produces an immediate pH rise, it suits wastewater neutralization and municipal water softening, while agricultural lime corrects soil acidity gradually.

What's the Difference Between Hydrated Lime and Hydraulic Lime?

Hydrated lime is a high-calcium, non-hydraulic lime. It does not set underwater; it hardens only by slowly absorbing carbon dioxide from the air and converting back into calcium carbonate. This makes it suitable for chemical dissolution, slurry preparation and wastewater treatment.

Hydraulic lime is made by calcining limestone that contains reactive silicates and aluminates, or by blending slaked lime with pozzolanic materials. Mixed with water, it sets and hardens even underwater, much like Portland cement, and is used for structural masonry and mortar restoration. Water treatment plants and neutralization tanks use high-calcium hydrated lime rather than hydraulic lime to avoid setting and blockages in tanks, pipelines and dosing equipment.

Bulk Hydrated Lime Manufacturers India: Packaging and Logistics

Continuous neutralization circuits and ZLD plants need dependable coordination with bulk hydrated lime manufacturers in India. Because fine calcium hydroxide reacts with atmospheric moisture and carbon dioxide over time, it must be stored dry and handled carefully, particularly during the monsoon. Receiving facilities typically use bag dump stations or pneumatic silo tankers for dry powder.

CMIPL supplies industrial minerals to paper, steel, plastics, PVC and water treatment industries across India and overseas. Alongside hydrated lime, CMIPL supplies quick lime in QL 5-25 mm, QL 25-75 mm, QL powder 0-3 mm, 200 Mesh and 300 Mesh grades. Buyers discuss packing, quantities and delivery schedules directly with the CMIPL sales team.
