Calcium Hypochlorite 70%: High‑Strength Solution for Pool Shock & Water Treatment

In the world of water sanitation and pool maintenance, Calcium Hypochlorite 70% stands out as one of the most powerful and reliable disinfectants available. Known for its high available chlorine content and rapid action, it is widely used for pool shock treatment, drinking water disinfection, and industrial sanitation. Whether you are restoring a cloudy swimming pool after heavy use or ensuring microbiologically safe water in municipal and industrial systems, understanding Calcium Hypochlorite 70% can significantly improve water management outcomes.

As a trusted supplier, exporter, and importer, Foxnut Group offers high‑quality Calcium Hypochlorite 70% manufactured under strict quality controls to meet international standards. This guide explains its composition, benefits, applications, safety practices, and how it compares with alternatives such as Calcium Hypochlorite 35% and Sodium Bicarbonate.

Understanding Calcium Hypochlorite 70%

Calcium Hypochlorite 70% is a white to off‑white granular or powdered solid with strong oxidizing and chlorinating properties. It releases hypochlorous acid when dissolved in water, which is the active agent responsible for killing bacteria, viruses, algae, and other pathogens.

Key Characteristics

• Available chlorine content: ≈70% (minimum)
• Physical form: Stable solid (granules or powder)
• Shelf life: Longer than liquid chlorine when stored correctly
• Classification: Oxidizing agent (UN 1748)

Compared with liquid chlorine or chlorine gas, Calcium Hypochlorite 70% is easier to store, transport, and dose, making it a preferred choice for exporters, importers, and large‑scale users.

Why Choose Calcium Hypochlorite 70% for Shock Treatment

Shock treatment involves adding a high dose of sanitizer to rapidly oxidize organic contaminants, chloramines, and algae. Calcium Hypochlorite 70% is highly effective for this purpose due to its fast dissolution and high chlorine yield.

Benefits for Pool Shock Treatment

• Rapid elimination of algae and bacteria
• Clears cloudy or green water quickly
• Removes unpleasant odors caused by chloramines
• Requires smaller quantities compared to lower‑strength products

Typical shock dosages depend on contamination level and pool volume. Always follow manufacturer instructions and local regulations to ensure safe and effective treatment.

Applications Beyond Swimming Pools

1. Drinking Water Treatment

Calcium Hypochlorite 70% is widely used for potable water disinfection, particularly in municipal systems, emergency response, and remote locations. Its stability and high chlorine content make it suitable for controlled, large‑scale dosing.

For drinking water applications, usage must comply with WHO, BIS, or local regulatory limits.

2. Wastewater & Industrial Water Treatment

• Oxidizes organic pollutants
• Reduces microbial load
• Helps meet discharge standards

3. Industrial & Surface Sanitation

Used in food processing units, dairies, and manufacturing facilities for equipment and surface disinfection.

4. Textile, Paper & Chemical Industries

Acts as an effective bleaching and oxidizing agent, often complemented by Sodium Bicarbonate for pH control.

Calcium Hypochlorite 70% vs Calcium Hypochlorite 35%

For users requiring fast, high‑impact disinfection, 70% grade is the preferred choice, while 35% grade is suitable for routine maintenance.

Role of Sodium Bicarbonate in Water Treatment

While Calcium Hypochlorite 70% disinfects, Sodium Bicarbonate helps balance pH and alkalinity. After shock treatment, sodium bicarbonate is often used to restore water balance, improving comfort and protecting equipment. Used together, they provide a comprehensive approach to water care.

Safe Handling and Usage Guidelines

To ensure safety and performance:

• Test water pH (ideal range: 7.2–7.8)
• Dissolve granules in water before application
• Wear gloves, goggles, and protective clothing
• Never mix with acids, ammonia, or organic materials
• Ensure proper ventilation in enclosed areas

Allow sufficient circulation time after dosing and verify chlorine levels before use.

Storage, Packaging & Environmental Considerations

• Store in a cool, dry, well‑ventilated area
• Keep away from heat, moisture, and combustible materials
• Use original sealed packaging (commonly 25 kg or 50 kg HDPE drums)

When used correctly, Calcium Hypochlorite breaks down into relatively harmless by‑products. Overuse should be avoided to prevent chlorinated residues and environmental impact.
