Market Applications of Aquavow Copper-Zinc Alloy Filter Media | A Multi-Functional Water Treatment Solution

Copper-zinc alloy filter media, also known as KDF Filter Media or KDF Process Media, has become an efficient and versatile solution in the water treatment market. Its unique electrochemical and physical properties enable it to address various water purification challenges. With the growing global demand for clean and safe water, the application scope of Copper Zinc Water Filtration is continuously expanding, covering multiple sectors from residential drinking water to industrial water treatment.

Core Chemical Composition and Material Properties

KDF media is a high-purity copper-zinc alloy, not merely a physical mixture but an electrochemically active copper-zinc bimetallic structure. Its main grades include:

• KDF-55: Composed of approximately 50% copper and 50% zinc, it is the primary grade widely used for removing residual chlorine, heavy metals, and inhibiting microorganisms.

• KDF-85: Contains about 85% copper and 15% zinc, specifically designed for efficient removal of iron and hydrogen sulfide from water.

Working Principle: Electrochemical Redox Reaction

When water flows through KDF media, copper and zinc form a micro-battery system in water: zinc acts as the anode losing electrons, while copper acts as the cathode gaining electrons, triggering multiple electrochemical reactions to achieve the following functions:

• Removal of Residual Chlorine: Electrons reduce residual chlorine (Cl₂, HOCl) into harmless chloride ions (Cl⁻). Chemical reaction:
  Zn + HOCl + H₂O → Zn²⁺ + Cl⁻ + H⁺

• Removal of Soluble Heavy Metals: Heavy metal ions like lead and mercury are reduced into insoluble metals and adhere to the media surface, e.g.,
  Pb²⁺ + 2e⁻ → Pb (solid)

• Microorganism Inhibition: Generated hydroxyl radicals and hydrogen peroxide disrupt microbial cell structures, achieving physical sterilization.

• Scale Prevention: Alters crystallization forms to prevent hard scale formation, promoting aragonite crystallization that is easily flushed away.

Main Application Areas

Drinking Water Purification

Copper Zinc Water Filtration Media is widely used in point-of-use water purifiers, effectively enhancing household drinking water safety:

• Residual Chlorine Removal: Reduces chlorine taste and disinfection byproduct risks, improving taste and safety.

• Heavy Metal Removal: Adsorbs and removes harmful heavy metal ions like lead and mercury through electrochemical action.

Industrial Water Treatment

In manufacturing, energy, chemical industries, KDF Material is used to control scale, corrosion, and microorganisms:

• Scale and Corrosion Control: Interferes with crystallization and forms protective layers to reduce equipment corrosion.

• Antimicrobial Advantages: Inhibits bacterial and algal growth in cooling systems and boilers, suitable for pharmaceuticals, food & beverage, and electronics industries.

Swimming Pools and Spas

As an alternative to chemical treatment, KDF media reduces chlorine usage:

• Inhibits algae and bacteria, reducing odors and equipment scaling.

• Improves water quality and lowers maintenance costs.

Aquaculture

Used to maintain water quality in aquaculture, ensuring aquatic health:

• Removes heavy metals and harmful substances, reducing toxicity risks to fish.

• Inhibits pathogens and excessive algal growth, improving survival rates and growth efficiency.
