Copper-Zinc Alloy Filtration Media 055: A Multifunctional Powerhouse in Water Treatment

In the ever-evolving world of water treatment, copper-zinc alloy (CuZn) has emerged as a revolutionary material, playing a crucial role in various purification processes. With its unique properties, it addresses multiple water quality issues, making it an essential component in filters, purifiers, and treatment systems.

✅ 1. Remove Residual Chlorine in Water

🔬 Reaction Equation

Zn + HOCl + H₂O + 2e⁻ → Zn²⁺ + Cl⁻ + H⁺ + 2OH⁻

💬 Explanation

Zinc (Zn) in the Aquavow CuZn alloy loses electrons and enters the solution as Zn²⁺.
Free chlorine (from HOCl) is reduced to chloride ions (Cl⁻), with water generating H⁺ and OH⁻ ions.
Copper (Cu) acts as a catalytic site and electron acceptor, enhancing chlorine reduction and removing residual chlorine effectively.


✅ 2. Remove Heavy Metals in Water

Aquavow CuZn alloy removes heavy metals via electrochemical redox reactions and catalysis.
Heavy metal ions are reduced and deposited on the alloy surface or incorporated into its crystal lattice.

🔬 Reaction Equations

Zn/Cu + Pb(NO₃)₂ → Zn/Cu/Pb + Zn(NO₃)₂

Zn/Cu + HgCl₂ → Zn/Cu/Hg + ZnCl₂

💬 Explanation

  • Heavy metals like Pb²⁺ and Hg²⁺ are reduced to metallic form and deposited onto Zn/Cu alloy.

  • Zinc is oxidized to salts such as Zn(NO₃)₂ or ZnCl₂.

  • Effectively removes Pb, Mn, Hg, Ag, Al, Cr, Cd, Cu, etc.


✅ 3. Remove Ferrous Iron (Fe²⁺) in Water

Ferrous iron in underground water or corroded steel pipes is oxidized by Aquavow alloy, forming insoluble compounds that can be removed.

🔬 Reaction Equations

2Cu + FeO → Cu₂O + Fe

4Fe + 3O₂ → 2Fe₂O₃

💬 Explanation

  • Copper reduces FeO to Fe, forming Cu₂O.

  • Fe reacts with oxygen, forming insoluble Fe₂O₃.

  • Fe₂O₃ can be filtered out, removing ferrous iron effectively.


✅ 4. Remove Hydrogen Sulfide in Water

🔬 Reaction Equations

Cu/Zn + H₂S → CuS + H₂

2H₂ + O₂ → 2H₂O

💬 Explanation

  • H₂S reacts with CuZn alloy via redox reaction.

  • Copper forms CuS (insoluble), while releasing H₂.

  • Released hydrogen combines with oxygen to form water.

  • Removes toxic, foul-smelling H₂S efficiently.


✅ 5. Remove Arsenic in Water

🔬 Reaction Equation

3Zn²⁺ + As₂O₃ + 6H⁺ → 2Zn₃As₂ + 3H₂O

💬 Explanation

  • Arsenic ions (As³⁺/As₂O₃) are reduced and deposited on CuZn alloy.

  • Zinc oxidizes, forming zinc arsenide (Zn₃As₂).

  • Arsenic is immobilized in solid form, making removal easier.


✅ 6. Reduce Mineral Scale in Water

💬 Explanation

  • Zinc ions alter calcium carbonate crystallization.

  • Calcite scale is converted to softer aragonite.

  • Electrochemical pH increase reduces carbonic acid solubility.

  • Loose solids form instead of hard scale, preventing equipment fouling.

KDF055 Media – Advanced Water Filtration Technology

KDF055 Media from our factory Kaidefei Fluid Technology is a high-purity copper-zinc alloy widely used in professional water filtration systems. Specially engineered for chlorine removal and the reduction of water-soluble heavy metals, KDF055 also effectively controls scale, bacteria, and algae growth—even in hot water environments.

Through a redox (electrochemical) reaction, KDF055 filter media removes contaminants such as lead, mercury, copper, and arsenic. It is commonly combined with activated carbon to maximize filtration efficiency and extend the life of downstream filters, including reverse osmosis, deionization, and ion exchange systems.

Key Functions of KDF055 Processing Media

  1. Scale Control: KDF055 raises the pH of water and changes calcium carbonate solubility, leading to softer, non-adherent aragonite scale instead of hard calcite deposits.

  2. Crystal Modification: Zinc ions released from KDF055 media alter crystal growth, preventing hard mineral scaling. Even low concentrations of zinc effectively inhibit calcite crystal formation.

  3. Microbial Control: Laboratory tests confirm that KDF055 reduces bacteria and algae growth, ensuring safer and cleaner water.

  4. Corrosion Prevention: KDF055 media reacts with iron oxides in corroded pipes, converting FeO into Fe₂O₃ solids, which can be removed by backwashing.

Recommended Operating Conditions

  • Bed depth: 6–10 inches

  • Flow rate: ~15 gpm/ft² (57 L/min)

  • Backwash: 10 minutes at 2× normal flow

  • Bed expansion: 10–15%

  • pH range: 6.5–8.5

  • Temperature: 35–212°F (2–100°C)

  • Effective particle removal: down to 50 μm

With its unique redox properties, KDF055 media is an ideal prefiltration material for residential, commercial, and industrial water purification systems.
