Application
Sodium Hypochlorite is a versatile solution used across numerous industries:
1.Water & Wastewater Treatment: Primary disinfectant for drinking water and for treating municipal and industrial wastewater.
2.Healthcare & Institutional: For surface disinfection, sanitizing medical equipment (at appropriate dilutions), and in laundry for bleaching and stain removal.
3.Food & Beverage Processing: Sanitizing processing equipment, surfaces, and fruit/vegetable washing.
4.Pulp & Textile Industry: As a bleaching agent for wood pulp, paper, and textiles.
5.Chemical Industry: As an oxidizing agent in various chemical synthesis processes.
6.Household & Commercial Cleaning: The active ingredient in many household bleaches and cleaning products.
Regular packing
- 1.IBC Totes (1000 Liters): Most efficient for large-volume industrial and municipal users.
- 2.200L / 55-Gallon Plastic Drums: Ideal for medium-scale users and distributors.
- 3.25L / 5-Gallon Plastic Jerry Cans: Suitable for smaller commercial or institutional facilities.
Customized Packing
- 1.Private label packaging for distributors.
- 2.Custom dilution strengths upon request.
- 3.Smaller bottle sizes (1L, 2L) for specific OEM or retail partnerships.
How to use
⚠️
Warning: Handle with care. Always use Personal Protective Equipment (PPE) including gloves, safety goggles, and protective clothing.
- 1.Dilution is Key: Always dilute with cold water before use. The required dilution ratio depends on the application and target disinfectant concentration (ppm of available chlorine).
- 2.For Surface Disinfection: A typical dilution is 1:100 (e.g., 10 ml of 10% solution per 1 liter of water) to achieve a ~1000 ppm solution. Apply by spraying or wiping.
- 3.For Water Treatment: Dosage is precisely controlled by metering pumps based on water flow and quality to maintain a safe residual chlorine level.
- 4.Mixing Precaution: Never mix sodium hypochlorite with acids or ammonia-based cleaners. This produces toxic chlorine gas or explosive compounds.
Advantages
- 1.Rapid Action: Works immediately upon contact to kill a wide range of microorganisms.
- 2.Proven Effectiveness: A time-tested, globally recognized disinfectant with a well-understood profile.
- 3.Cost-Effective: Generally has a lower upfront cost per unit of chlorine compared to solid alternatives.
- 4.Easy to Apply & Dose: Liquid form allows for easy mixing and precise dosing with pump systems.
- 5.Leaves No Solid Residue: Unlike some solid chlorine products, it dissolves completely without leaving behind insoluble particles.
Storage Method
Proper storage is critical to maintain strength and safety.
- 1.Store in a Cool, Dark Place: Temperature should ideally be below 20°C (68°F). Heat and sunlight dramatically accelerate decomposition.
- 2.Use Ventilated, Corrosion-Resistant Areas: Store in a well-ventilated space. Tanks and containers should be made of compatible materials like polyethylene (HDPE), fiberglass, or rubber-lined steel.
- 3.Short Shelf Life: Plan for first-in, first-out (FIFO) usage. A 12.5% solution can lose significant strength within a few weeks, especially in suboptimal conditions.
- 4.Isolate from Incompatibles: Store far away from acids, ammonia, organic chemicals, and flammable materials.
FAQ
Q1: What is the shelf life of Sodium Hypochlorite?
A1: Its shelf life is limited. A 12.5% solution stored at 20°C (68°F) can lose 30-50% of its strength within 3-4 months. Higher temperatures and exposure to light or metals will cause it to degrade much faster. We recommend using it as quickly as possible after delivery.
Q2: Why does it sometimes have a yellow or brown color?
A2: The pale greenish-yellow color is normal. A darker yellow or brown color can indicate the presence of dissolved iron or other metals, which can catalyze decomposition. It can also signal that the product is old and has degraded.
Q3: How does it compare to solid chlorine (e.g., TCCA, Calcium Hypochlorite)?
A3:
Sodium Hypochlorite (Liquid): Faster acting, no residue, easier to dose in liquid systems, but has a short shelf life, is corrosive, and expensive to transport (mostly water).
Solid Chlorine: Long shelf life, more concentrated, cheaper to transport and store, but dissolves slower and may leave insoluble residue.
Q4: Is it corrosive?
A4: Yes, it is highly corrosive. It can damage metals, degrade many plastics, and irritate skin and eyes. Always use recommended materials (HDPE, PVC, fiberglass) for handling and storage, and always wear PPE.
Q5: Why is there a strong chlorine smell?
A5: The smell indicates that the solution is decomposing and releasing chlorine gas. This is normal in well-ventilated areas but can be pronounced if the product is old, stored improperly, or if it has been contaminated.
