Cal Hydro is an ultra fine high purity calcium carbonate powder created for the specific needs of potable water treatment. It plays a vital role in municipal water systems and bottled water facilities where stable pH and high clarity are essential for consumer safety and regulatory compliance. The product neutralises acidity and acts as a dependable buffering agent which helps maintain the desired pH levels throughout the treatment and distribution process.
Its exceptional fineness ensures that the powder dissolves rapidly when introduced through dosing pumps, slurry preparation systems or calcite filter beds. This quick dissolution supports uniform treatment of water streams and minimises the risk of inconsistent output quality. With a calcium carbonate content of not less than ninety seven per cent and very low levels of magnesium oxide, iron oxide and silica, Cal Hydro is engineered to deliver purity and effectiveness in every application.
Cal Hydro offers a combination of purity, reactivity and operational ease which makes it a reliable material for water treatment operations.
Overall, the product delivers stable performance that supports consistent production of safe and clear drinking water.
Cal Hydro is used in a range of potable water treatment applications where precise pH adjustment and water clarity are essential. It is suited for use in dosing pump systems where quick and complete dissolution is important for continuous operations.
In short, Cal Hydro serves as a consistent and highly responsive aid for maintaining safe and clear drinking water.
Cal Hydro is produced from high purity calcium carbonate sources that are refined to deliver a product with low moisture and low impurity levels. The material is processed into an ultra fine powder with a particle size above two hundred mesh which ensures rapid reactivity in water treatment systems.

High-grade lime sweetener corrects marginal lime, balances high-silica mixes, improves nodulization and kiln throughput and supports consistent strength development at grinding—stabilizing clinker and cement performance across plants.
As a fluxing agent, lime optimizes slag formation, reduces impurities and improves overall melt quality. In sintering, high-grade lime binds fines and lowers melt temperature for strong, reactive sinter—supporting efficient blast furnace and cleaner steel in secondary metallurgy.
Chemical-grade lime is a critical raw material for producing high-purity lime and calcium derivatives. Its consistent CaCO₃ content, low silica and minimal iron ensure predictable reactivity and clean conversion in calcination, hydration and chemical reaction processes. Whether in rotary kilns, PFR kilns, or shaft kilns, it supports reactive lime, PCC and specialty calcium compounds.
CFB and coal-based units rely on lime injection/FGD for SO₂ capture. High-reactivity lime improves capture efficiency in both retrofit and new builds—helping plants meet stringent air-quality norms.
High-calcium, low-iron lime lowers melting temperatures and stabilizes batch chemistry. Tight sizing ensures uniform melt flow; ultra-low iron is critical for solar, optical and premium architectural glass clarity.
High-purity CaCO₃ provides bioavailable calcium for bone mineralization, muscle function and eggshell formation. Controlled particle sizes enable uniform mixing, predictable release and consistent feed performance across growth stages.
To manage soil acidity, lime supplies calcium (and magnesium where dolomitic), improving structure, microbial activity and nutrient availability. Result: better root development, balanced uptake and improved yields.
GCC/lime powder is a cost-effective mineral extender for plastics, paints, rubber and more—improving bulk density, workability, rheology, dimensional stability and throughput with consistent sizing and low moisture.
