Calcium hypochlorite

Calcium hypochlorite White granules with a strong chlorine odor.

Strong oxidizing agent. Contact with water or moist air can cause combustion and explosion. Mixing with alkaline substances can cause an explosion. Exposure to organic matter is a risk of combustion.

Applications

Water Treatment and Disinfection

• Swimming Pools and Spas: Dosed at 1-3 ppm for shock treatment and routine chlorination, eliminating bacteria, algae, and viruses while stabilizing pH.
• Drinking Water Purification: Applied at 0.5-2 mg/L in municipal and emergency systems to achieve 99.99% pathogen inactivation per EPA guidelines.

Sanitation and Cleaning

• Food Processing and Healthcare: Surface disinfectant at 200-500 ppm solutions for equipment and surfaces, preventing cross-contamination in dairies and hospitals.
• Wastewater and Sewage: Oxidizer at 5-20 ppm to control odors and reduce BOD in treatment plants.

Industrial Uses

• Bleaching and Textile Processing: 0.5-2% solutions for pulp, paper, and fabric whitening, providing uniform brightness without fiber damage.
• Aquaculture and Agriculture: Pond and irrigation disinfectant at 1-5 ppm to manage bacterial loads in fish farming and crop protection.

Frequently Asked Questions (FAQs)

What is Calcium Hypochlorite?

Calcium Hypochlorite is an inorganic chlorine compound with formula Ca(ClO)₂ and CAS 7778-54-3, used as a disinfectant and bleach. It’s a stable granular solid releasing hypochlorous acid in water for broad-spectrum microbial control.

How is Calcium Hypochlorite applied in pool maintenance?

Dissolve 1-2 kg per 10,000 gallons for shocking; maintain 1-3 ppm free chlorine with daily testing. Pre-dissolve in buckets to avoid cloudiness and test pH post-addition.

Is Calcium Hypochlorite safe for drinking water treatment?

Yes, it’s EPA-approved at ≤20 mg/L, with residual chlorine <4 mg/L for disinfection; use in well-ventilated areas and follow contact time guidelines for full efficacy.

What is the shelf life of Calcium Hypochlorite?

Stored sealed and dry below 30°C, it retains 90% chlorine for 1-2 years; avoid moisture to prevent decomposition and monitor available chlorine periodically.

Can Calcium Hypochlorite be mixed with other chemicals?

It reacts violently with acids or ammonia—never mix directly; compatible with cyanuric acid for stabilization but test for compatibility in blends.

Does Calcium Hypochlorite affect water pH?

Its alkaline pH (11-13) raises system pH slightly; adjust with muriatic acid if needed, but it buffers effectively in pools without frequent corrections.

What packaging options are available for Calcium Hypochlorite?

We offer 45kg plastic drums, 25kg pails, and 1000kg fiber drums, all moisture-proof and labeled for oxidizer transport compliance.

For dosing calculations, safety protocols, or bulk orders, our water treatment specialists provide customized recommendations.
