Calcium Hypochlorite 65-70% — Granular & Tablet Chlorine for Water Disinfection
Calcium hypochlorite is the world's most widely used solid chlorine disinfectant for drinking water treatment, swimming pool sanitation, industrial disinfection and wastewater treatment. With 65% to 70% available chlorine, calcium hypochlorite delivers significantly stronger disinfection than liquid sodium hypochlorite (10-15% chlorine), while being more stable, cheaper to transport and easier to store in hot climates. Everglory Industrial, an ISO 9001 certified calcium hypochlorite manufacturer with over 15 years of export experience, supplies high-purity calcium hypochlorite to water utilities, pool chemical distributors, municipalities and industrial buyers across 60+ countries worldwide.
Why Choose Our Calcium Hypochlorite?
As a direct calcium hypochlorite manufacturer, Everglory Industrial controls every step of production — from raw material selection to UN-certified packaging. Every batch is laboratory tested for available chlorine content, moisture, thermal stability and particle size before shipment. Third-party SGS inspection reports are available on request, and full Material Safety Data Sheets (MSDS) are provided in English and French to simplify customs clearance and regulatory compliance in your country.
Key advantages of our calcium hypochlorite:
- High available chlorine: 65% to 70% — lower dosage rates and optimized freight costs compared to liquid chlorine
- Stable solid form: Granular and tablet formats eliminate leakage and gas-off hazards of liquid chlorine — ideal for long-distance ocean shipping
- Broad-spectrum disinfection: Effectively destroys bacteria (E. coli, cholera, typhoid), viruses, algae and protozoa in drinking water and wastewater
- Fast solubility: Fully dissolves in 15-30 minutes for rapid treatment of municipal networks, wells and storage tanks
- UN-certified packaging: 25kg/50kg plastic drums certified UN 2880, compliant with IMDG marine transport regulations
- Flexible supply: Stable production capacity of 2,000+ MT per month ensures on-time delivery even for large container orders
- Long shelf life: 24 months minimum in original sealed packaging when stored cool, dry and ventilated
Calcium Hypochlorite Technical Specifications
Calcium Hypochlorite Applications
Calcium hypochlorite is trusted by water professionals, pool operators and industrial facilities worldwide for the following applications:
1. Drinking Water Treatment
Calcium hypochlorite is the disinfectant of choice for municipal water treatment plants, community water systems and emergency relief operations. A dose of 2-5 mg/L of available chlorine eliminates waterborne pathogens including cholera, typhoid, dysentery and hepatitis A. Unlike chlorine gas, calcium hypochlorite requires no complex chlorination equipment or permanent power supply — simple dissolution followed by metering via dosing pump or manual addition is sufficient, making it the ideal solution for rural communities, boreholes and decentralized water networks.
2. Swimming Pool Sanitation
Hotels, resorts, aquatic centers and residential pools use calcium hypochlorite to maintain 1-3 ppm of free residual chlorine in pool water. The 200g 3-inch tablet format provides slow, controlled dissolution through skimmers or floating dispensers — continuous 24-hour disinfection without frequent manual intervention. Calcium hypochlorite also acts as a shock treatment to eliminate algae blooms and combined chlorine (chloramines).
3. Industrial & Food Processing Disinfection
Food processing plants, breweries, abattoirs and fish processing facilities use calcium hypochlorite solutions at 200-500 ppm for surface, equipment and rinse-water disinfection. The WHO, FAO and Codex Alimentarius recognize calcium hypochlorite as a safe disinfectant for food-contact applications at appropriate concentrations, supporting compliance with international food safety standards such as HACCP and FSSC 22000.
4. Wastewater & Effluent Treatment
Municipal and industrial wastewater treatment plants use calcium hypochlorite for final effluent disinfection before discharge. A residual concentration of 1-5 mg/L destroys fecal coliform bacteria and meets environmental discharge standards in most countries. Calcium hypochlorite is also widely used for odor control and sludge treatment in sewer systems.
Dosage & Usage Guidelines
The calcium hypochlorite dosage depends on the water volume to be treated, raw water quality and target chlorine concentration. The table below provides indicative dosages for the most common applications:
Safety warning: Calcium hypochlorite is a strong oxidizer (UN Class 5.1). Never mix with acids, ammonia-based compounds or other incompatible chemicals — toxic chlorine gas may be released. Wear PPE (gloves, goggles, mask) when handling. Store in a cool, dry, ventilated area away from combustible materials. Always consult the MSDS before use.

Frequently Asked Questions (FAQ)
Q: What is the difference between calcium hypochlorite and sodium hypochlorite?
Calcium hypochlorite is a solid containing 65-70% available chlorine, while sodium hypochlorite (liquid bleach) contains only 10-15%. Calcium hypochlorite is more concentrated, more stable, cheaper to transport and has a much longer shelf life (24 months vs 3-6 months for liquid). It is therefore preferred for long-distance shipping and storage in hot climates.
Q: What is the calcium hypochlorite dosage for drinking water disinfection?
For drinking water, the recommended dose is 2-5 mg of available chlorine per liter of water, depending on raw water quality. Free residual chlorine should be 0.2-0.5 mg/L at the point of consumption. Always verify residual chlorine with a DPD test kit after treatment.
Q: What is the minimum order quantity (MOQ) for calcium hypochlorite?
Our standard MOQ is 5 metric tons for granular calcium hypochlorite and 1 x 20ft container (approximately 14-24 MT) for the most economical sea freight rates. For OEM private label orders, the minimum is 5 MT. Trial orders are welcome to evaluate product quality before committing to container quantities.
Q: Can you provide samples before placing an order?
Yes. Free samples (500g) are available for qualified buyers. Shipping costs for samples are covered by the buyer. Samples are dispatched within 3-5 working days along with the corresponding COA and MSDS so you can verify quality before ordering.
Q: How should calcium hypochlorite be stored in tropical climates?
Store in original sealed packaging in a cool, dry, well-ventilated warehouse below 30°C, away from direct sunlight and heat sources. Avoid contact with combustible materials, acids and ammonia compounds. Under these conditions, shelf life is 24 months minimum.
Q: Do you offer OEM packaging and private label?
Yes. Everglory Industrial provides a complete OEM and private label service. We print your labels with your logo, contact details and batch numbers. We also offer custom packaging configurations — drums, cartons or big bags — according to your market requirements. Contact us to discuss your specific needs.
Buying tip: To optimize your import costs, order calcium hypochlorite in 20ft container (≈ 14-24 MT) quantities. Larger volumes significantly reduce the unit sea freight cost. Request a CIF quote to compare delivered pricing to your destination port.
