Calcium Sulfite Balls: How to Efficiently Remove Residual Chlorine in Water Purification Media

Is Your Tap Water Truly Safe?  

Every time you turn on the faucet, have you ever wondered: Could the seemingly clear tap water contain harmful substances like chlorine and heavy metals? According to the World Health Organization, long-term consumption of chlorinated water may pose health risks, and traditional water purification methods may not fully resolve these issues. Today, we introduce a revolutionary water purification media—Calcium Sulfite Balls—and explore how this advanced technology safeguards household water safety.  

 

I. Water Purification Media: The First Line of Defense for Water Quality  

Water purification media serve as the core of water treatment systems, directly impacting filtration efficiency. Common media include:  

1. Activated Carbon: Adsorbs organic matter and odors but has limited chlorine removal efficiency.  

2. KDF (Copper-Zinc Alloy): Removes heavy metals and partial chlorine through redox reactions but requires regular replacement.  

3. Ion Exchange Resin: Softens water but cannot address chlorine.  

 

Calcium Sulfite Balls, as next-generation chlorine-removal media, have become an industry benchmark due to their high reactivity and longevity. They convert residual chlorine into harmless sulfates through chemical reactions, eliminating the need for regeneration and making them ideal for both residential and industrial use.  

 

II. The Working Principle of Calcium Sulfite Balls  

Calcium sulfite (CaSO₃) is a strong reducing agent that reacts with residual chlorine in water:  

CaSO₃ + Cl₂ + H₂O → CaSO₄ + 2HCl  

The reaction produces calcium sulfate and hydrochloric acid, both harmless. This process requires no electricity and occurs instantaneously (within 0.2 seconds), ensuring efficient chlorine removal.  

 

III. ZONE Calcium Sulfite Balls: Five Generations of Technological Innovation Redefining Industry Standards  

As a leader in China’s water purification media sector, ZONE has spent over 21 years advancing Calcium Sulfite Ball technology:  

  

- 1st Generation (2007): Smooth surface with basic chlorine removal.  

- 5th Generation (2022): Over 90% high-purity calcium sulfite with a porous structure, maximizing specific surface area. A 20g dosage purifies 20,160 liters of water (compared to an industry average of 500 liters).  

Key Advantages:  

1. High Efficiency: Removes >96.67% of chlorine (tested at 0.3mg/L chlorine, 6.5L/min flow rate).  

2. Longevity: Lasts 6–12 months per batch (depending on water quality).  

3. Safety & Sustainability: Certified by SGS, CNAS, and others; no secondary pollution.  

4. Customizable Sizes: Available in 0.25–6mm diameters for showers, faucets, and more.  

 

Test

Pour the residual chlorine solution with a concentration of 1ppm into 25g ZONE calcium sulfite ball and the residual chlorine will be removed instantly.

 

IV. Applications of Calcium Sulfite Balls  

- Residential Use: Shower heads (15–30g), faucets (25–50g), water purifier cartridges (10–500g).  

- Commercial Settings: Swimming pools, bathhouses, hotel water systems.  

- Industrial Use: Chemical wastewater treatment, food processing water purification.  

 

Case Study: A U.S. water purification brand using ZONE’s 5th-generation balls saw a 40x lifespan improvement and 98% customer satisfaction.  

 

V. Authoritative Certification and Measured Data  

- SGS Test Report: Heavy metal content below EU RoHS standards.  

- Dynamic Testing: 45g of media maintained 62.5% chlorine removal efficiency at 1.0–1.2mg/L chlorine and 2L/min flow rate for 3,000 liters.
