Calcium Chloride Applications and Environmental Benefits in Water Treatment
Calcium chloride (CaCl₂) is widely used in water treatment, wastewater treatment, de-icing, dust control, and other industrial applications. It is available in anhydrous (CaCl₂·0H₂O) and hexahydrate (CaCl₂·6H₂O) forms. Anhydrous calcium chloride is preferred for dehumidification and de-icing, while hexahydrate calcium chloride is used in water softening and treatment due to its cost-effectiveness. Applications & […]

Iodine Number in Activated Carbon: Why It Matters
What is Iodine Number? The iodine number measures activated carbon’s micropore surface area (mg/g), indicating its ability to adsorb contaminants. Iodine Number & Applications: 1. 600–800 mg/g → Medium adsorption (industrial wastewater, general filtration) 2. 900–1000 mg/g → High adsorption (drinking water, food processing) 3. 1100+ mg/g → Ultra-high adsorption (pharmaceuticals, VOC removal, gold […]
