Calcium Hypochlorite 70% Granular Industrial Grade

Calcium Hypochlorite 70% Granular Industrial Grade is a chlorine-based oxidizing chemical widely used in industrial and municipal water treatment, swimming-pool sanitation, wastewater treatment, textile and pulp bleaching, and other controlled disinfection applications.

The product is offered with a target Available Chlorine content of ≥70%, subject to the applicable manufacturer's specification and batch Certificate of Analysis.

Calcium Hypochlorite is typically supplied as white to light-yellow granules with a characteristic chlorine odor. It releases hypochlorite species when dissolved in water and is commonly selected where a solid chlorine source is required for industrial treatment processes.

The granular form provides convenient storage, transport and controlled preparation when handled in accordance with the current Safety Data Sheet and applicable operating procedures.

Applications

Water Treatment

Calcium Hypochlorite is commonly used in controlled water-treatment systems for:

• Water disinfection
• Municipal water-treatment processes
• Industrial process-water treatment
• Wastewater treatment
• Circulating-water sanitation
• Emergency water-treatment operations where approved

Dosage and regulatory suitability must be established by qualified personnel and applicable water-treatment regulations

Swimming Pool Treatment

Applications include:

• Pool-water sanitation
• Microbial control
• Algae-control programs
• Maintenance of available chlorine levels

Use must follow the applicable pool-treatment instructions, local regulations and product labeling.

Wastewater Treatment

Calcium Hypochlorite may be used for:

• Wastewater disinfection
• Microbial control
• Selected oxidation processes
• Industrial effluent treatment

Suitability and dosing depend on the wastewater composition and treatment objective.

Textile & Pulp Applications

Calcium Hypochlorite may be used as a bleaching agent in selected:

• Textile-processing operations
• Cotton bleaching
• Fiber treatment
• Pulp processing
• Paper-manufacturing processes

The concentration and operating conditions must be selected according to the process requirements.

Industrial Sanitation

Appropriate grades may be used in controlled industrial sanitation programs involving:

• Equipment sanitation
• Industrial surfaces
• Process-water systems
• Selected facility-disinfection procedures

Do not claim food-contact approval unless your supplied product and application satisfy the applicable regulatory requirements.

Drinking-Water Disclaimer

Dongkwang publicly positions Calcium Hypochlorite 65–70% for drinking-water disinfection.

However, this ECHEMI listing is:

INDUSTRIAL GRADE

Do not state that the material is approved for potable-water treatment in a particular country unless the actual product has the necessary quality specification, registrations, approvals and documentation for that market.

A safer commercial statement is:

Suitable for controlled water-treatment applications subject to applicable regulatory and process requirements.

Packaging & Storage

Packaging

Recommended standard export package:

45 kg compatible HDPE drum with secure moisture-resistant closure

Alternative configurations may include:

• 25 kg drum
• 40 kg drum
• 50 kg drum

Only state packaging you actually supply.

Calcium Hypochlorite is an oxidizing dangerous good, so packaging must meet applicable transport requirements.

Storage

Store in:

• A cool location
• Dry conditions
• Well-ventilated chemical storage area
• Original tightly closed packaging
• An area protected from contamination
• A facility suitable for oxidizing chemicals

Keep away from:

• Acids
• Organic materials
• Oils and grease
• Combustible substances
• Reducing agents
• Ammonia
• Amines
• Urea
• Reactive sulfur compounds
• Other incompatible chemicals identified in the current SDS

Protect the material from heat, moisture and contamination.

Handling & Safety

Calcium Hypochlorite is a strong oxidizing chemical.

Personnel should follow the current product-specific SDS.

Recommended controls may include:

• Appropriate chemical-resistant gloves
• Protective clothing
• Chemical splash goggles
• Face protection where required
• Suitable respiratory protection where dust exposure warrants it
• Adequate ventilation
• Dust-control measures

Avoid contaminating Calcium Hypochlorite with:

• Acids
• Fuels
• Oils
• Organic chemicals
• Reducing agents
• Ammonia-containing products
• Other incompatible substances

Contact with incompatible materials may cause rapid decomposition, fire, toxic gas release or other hazardous reactions.

Transport Information

Important: Transport classification depends on hydration state

Calcium Hypochlorite is generally transported as a:

Class 5.1 Oxidizer

However, the correct UN number must be selected from the actual product composition and moisture content.

Dry Product

For dry Calcium Hypochlorite containing more than 39% available chlorine:

UN Number: UN 1748

Proper Shipping Name: CALCIUM HYPOCHLORITE, DRY

Hazard Class: 5.1

Hydrated Product

If the product contains approximately 5.5% to 16% water, the applicable entry may instead be:

UN Number: UN 2880

Proper Shipping Name: CALCIUM HYPOCHLORITE, HYDRATED or CALCIUM HYPOCHLORITE, HYDRATED MIXTURE

Hazard Class: 5.1

Critical Transport Rule

Do not automatically publish:

UN 1748

if your actual 70% product has 5.5–10% moisture.

Confirm the correct UN classification from:

• Current supplier SDS
• Actual moisture content
• Dangerous-goods declaration
• Applicable ADR / IMDG / IATA / national rules

The commercial TDS and shipping documents must all correspond to the same product form.
