In the ever-evolving field of water treatment, copper-zinc alloy—also known as CuZn from our factory Kaidefei Fluid Technology has emerged as an innovative material, playing a vital role in various purification processes. With its unique properties, it effectively addresses multiple water quality challenges, making it an essential component in water filter cartridges, purifiers, and treatment systems.

Residual Chlorine Removal

One of the most important applications of copper-zinc alloy is the removal of residual chlorine from water. Chlorine is widely used in municipal water systems to disinfect and eliminate harmful bacteria. However, residual chlorine can cause unpleasant taste and odor and may react with organic matter to form potentially harmful by-products. Through a redox (oxidation-reduction) reaction, CuZn reduces chlorine to harmless chloride ions—improving taste, smell, and safety of drinking water.

Inhibition of Heavy Metals and Bacterial Growth

Beyond chlorine removal, copper-zinc alloy excels in controlling heavy metals and inhibiting bacterial growth. It removes lead, mercury, and cadmium by converting them into insoluble forms through redox reactions, preventing harm to human health. Its natural antimicrobial properties disrupt bacterial cell walls, inhibit reproduction, and prevent biofilm formation—protecting against pathogens such as E. coli and Legionella.

Prevention of Scale and Algae Formation

Scale and algae buildup are persistent issues in water systems, particularly in high-temperature or sunlit environments. CuZn helps stabilize mineral content, interferes with calcium carbonate crystallization, and suppresses scale formation. Meanwhile, its antimicrobial effects inhibit algae growth—protecting pipelines and storage systems, while enhancing efficiency and extending equipment lifespan.

Wide Applications and Certified Safety

With its outstanding purification performance, copper-zinc alloy is widely used in household purifiers, commercial drinking water systems, industrial treatment units, and wastewater recovery. 

Whether as pre-filtration or primary media, it delivers consistent water quality. Premium copper-zinc filtration media—such as those by AquaVow—are NSF-certified and comply with NSF/ANSI Standard 42, ensuring safety and effectiveness in drinking water applications.
