2. Industrial Use: Sodium dichloroisocyanurate granules are widely used in food processing, beverage manufacturing, and dairy for equipment sanitation, surface disinfection, and maintaining hygiene standards.

3. Agriculture: These granules are used for disinfecting livestock farms, poultry farms, and aquaculture environments to prevent the spread of diseases among animals.

4. Public Health: Sodium dichloroisocyanurate granules can be used in hospitals, clinics, and other healthcare facilities for disinfecting surfaces and medical equipment to control infection rates.

5. Household Disinfection: SDIC granules can be used for sanitizing kitchens, bathrooms, and other areas prone to microbial contamination.

6. Textile Industry: SDIC also has a good performance in fabric bleaching.

Packaging

Sodium dichloroisocyanurate granules are typically packaged in high-density polyethylene (HDPE) drums, fiber drums, or plastic pails to ensure safe and convenient handling. Common packaging sizes range from 1 kg, 5 kg, 10 kg to 50 kg, catering to various customer needs.

For bulk orders, sodium dichloroisocyanurate granules can be supplied in jumbo bags or customized packaging as per client requirements. Each package is labeled with product information, safety guidelines, and handling instructions to ensure proper use and storage.

Guidance for Use in Swimming Pools

Sodium dichloroisocyanurate is the best choice of quickly raising the chlorine level or daily disinfection of swimming pools and spas. It is quickly dissolved and will not damage liner.

Important • Use safety gloves and safety mask to protect skins and eyes from contacting with this product.
• Never add sodium dichloroisocyanurate granules when the pool is being used, and always wait at least 30 minutes after added.
• The pool water should be chlorinated at a level of 1.0 to 3.0 ppm while the pH should be keep in the range of 7.2 to 7.6.

Directions for Use 1. Fill a plastic bucket with pool water. Add the correct weight of SDIC granules to the bucket, stir gently to mix thoroughly.
2. Slowly pour the solution into the pool immediately above the pool return inlet whilst the pool circulation system is running.
3. Keep the pool circulation system running for at least 30 min after added.
4. Test the pool water to ensure that the required chlorine concentration of 1.0 to 3.0 ppm has been established.

General Precautions • Ensure that the filter and the pool circulation system work well.
• Always handle products in well ventilated area.
• Always wash hands thoroughly after handling pool chemicals.

Caution • Keep in a dry, cool and ventilated place away from light.
• Keep out of reach of children.
• Keep away from heat and sources of ignition.
• Keep the container cap close tightly after use.
• Store away from strong reducing agents, strong acids or water.

Safety • Minimize contact.

Frequently Asked Questions

What is Sodium Dichloroisocyanurate (SDIC) and how does it work?

Sodium Dichloroisocyanurate (SDIC) is a chlorine-based disinfectant and biocide. When dissolved in water, it releases active chlorine, which acts as a powerful oxidizing agent to destroy a broad spectrum of pathogens including bacteria, viruses, fungi, and algae, making it highly effective for sanitation and disinfection purposes.

What is the difference between SDIC Granules and SDIC Dihydrate Granules?

The key difference lies in their available chlorine content and molecular formula. SDIC Dihydrate Granules (CAS: 51580-86-0) contain a minimum of 55–56% available chlorine, while standard SDIC Granules (CAS: 2893-78-9) offer a higher minimum of 60% available chlorine. Both appear as white granules with a chlorine odor.

How should SDIC granules be used in a swimming pool?

Dissolve the correct amount of SDIC granules in a plastic bucket filled with pool water, stir gently, and slowly pour the solution near the pool return inlet while the circulation system is running. Wait at least 30 minutes before allowing swimmers in the pool, and test the water to confirm a chlorine level of 1.0–3.0 ppm and a pH of 7.2–7.6.

What industries commonly use SDIC granules?

SDIC granules are widely used across multiple industries including water treatment (swimming pools, drinking water, wastewater), food processing and beverage manufacturing, agriculture (livestock and aquaculture), healthcare (hospitals and clinics), household sanitation, and the textile industry for fabric bleaching.

What certifications does SDIC hold, and what packaging options are available?

SDIC granules are certified under NSF, REACH, and BPR standards. They are available in a range of packaging options including HDPE drums, fiber drums, and plastic pails in sizes from 1 kg to 50 kg. Bulk orders can be accommodated in jumbo bags or customized packaging according to client requirements.

What safety precautions should be taken when handling SDIC granules?

Always wear safety gloves and a mask when handling SDIC granules. Store in a dry, cool, and well-ventilated area away from heat, light, children, strong reducing agents, and strong acids. Never mix SDIC with any other chemical products. After handling, wash hands thoroughly. Ensure the container is tightly sealed after each use.
