How to use
1
Personal Protection:
Wear protective glasses, chemical-resistant gloves, a mask, and a long-sleeved work suit when handling.
2
Solution Preparation:
Use plastic, glass, or ceramic containers.
Golden Rule: Always add the product slowly to the water, stirring while adding. Never pour water into the product!
3
Calculate the dosage based on the desired concentration.
For example, to prepare a 0.1% available chlorine solution, add approximately 0.14 grams of this product per liter of water (based on 70% available chlorine).
4
Application Dosage:
Drinking Water/Wastewater: Use a dosing device for precise dosing, depending on the flow rate and level of contamination.
Swimming Pools: Place the tablet in a floating or embedded dosing device and allow it to dissolve slowly.
Surface Disinfection: Spray or wipe with the prepared solution. For optimal results, allow it to sit for 30 minutes.
Advantages
Compared to ordinary bleaching powder (30% available chlorine):
1. Double the effectiveness:
Contains more than twice the available chlorine of ordinary bleaching powder, requiring less usage and achieving greater cost-effectiveness.
2. Excellent stability:
Resists moisture and caking, extending shelf life and reducing waste.
Compared to liquid sodium hypochlorite (such as 84 disinfectant):
1. Easy to store and transport:
Its solid form eliminates the risk of leakage, significantly reducing transportation and storage costs.
2. Long shelf life:
While liquid products are prone to decomposition, this product maintains its effectiveness for extended periods.
3. Core technological advantages:
Its sodium-based process ensures high purity and low impurity content, resulting in stable and reliable performance.
Storage Method
1. Store in a cool, dry, well-ventilated warehouse.
2. Keep away from heat, fire, and direct sunlight.
3. Keep sealed. After opening, securely fasten the inner bag to prevent moisture absorption.
4. Do not store or mix with organic matter, flammable materials, reducing agents, or acids (such as toilet cleaners).
FAQ
Q1: What is the difference between this product and ordinary bleaching powder?
A1: The main differences lie in the available chlorine content and stability. This product has an available chlorine content of ≥70%, more than double that of ordinary bleaching powder (approximately 30%), meaning it is more efficient and requires less use. Furthermore, our sodium process makes it more stable and less susceptible to ineffectiveness.
Q2: Why does precipitation occur during use?
A2: This is normal. When calcium hypochlorite is dissolved in water, a small amount of insoluble calcium salts (such as calcium carbonate) introduced during the production process forms a white precipitate. This precipitate itself is non-toxic, but it is recommended to let the precipitate sit or use the supernatant to prevent clogging of spray equipment.
3. Q: What are the advantages of this granular formulation?
A: Granular products offer the following significant advantages over powders:
Less dust: This improves the working environment, reduces respiratory irritation to operators, and reduces the risk of corrosion in the equipment area.
Controllable Solubility: The moderate dissolution rate makes it easy to operate manually or with automated dosing equipment, and it resists agglomeration.
Easy Metering: Simple containers allow for rough metering, making it suitable for dosing of all sizes.

4. Q: How should I dissolve and dose this product?
A: We recommend using a dedicated calcium hypochlorite dissolution and dosing system.
Preparing the stock solution: In a plastic dissolution tank, slowly add the granules to clean water to create a stable calcium hypochlorite solution with a concentration of 5%-10%. Demineralized water is recommended to minimize scale formation.
Mixing and Aging: Mechanically stir until completely dissolved, then allow to settle for a short time to allow insoluble matter to settle.
Dosing: Use a metering pump to accurately dose the supernatant (stock solution) into the water to be treated.
Never dissolve the product directly into a pool! Dissolve it completely in the dissolution tank first.
