NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight a cornerstone product in advanced water treatment: KDF 55 Filtration Media. This highly effective media, an alloy primarily composed of copper and zinc, represents a significant advancement in achieving cleaner and safer water for a variety of applications, from household use to industrial processes.

KDF 55 Media is engineered specifically to address some of the most common and persistent contaminants found in water supplies. Its primary function revolves around its unique electrochemical properties. Through a redox (reduction-oxidation) process, the copper and zinc in the media interact with unwanted substances in the water, effectively neutralizing or removing them. This mechanism is particularly potent against chlorine, a widely used disinfectant but one that can impart unpleasant tastes and odors and potentially form harmful byproducts. KDF 55 excels at reducing or completely removing free chlorine through this electron exchange.

Beyond chlorine, this filtration media is highly effective at tackling various water-soluble heavy metals. The electrochemical reaction facilitates the precipitation or plating out of heavy metals such as copper, lead, mercury, and arsenic. This is crucial for ensuring drinking water meets stringent safety standards and for protecting plumbing fixtures from corrosive effects caused by these metals. The source material confirms that tests on water treated with KDF 55 show heavy metal levels well within safe limits for drinking water.

Another significant benefit of KDF 55 Media is its ability to control microbial growth. The redox process creates an environment unfavorable for bacteria and algae. Furthermore, the release of trace amounts of zinc ions during the process can also have a bacteriostatic effect, inhibiting the reproduction of microorganisms. This makes KDF 55 a valuable component in filtration systems where controlling biological fouling is important, even in warmer water conditions.

Scale formation, particularly calcium carbonate scale, is a common problem in many water systems. KDF 55 Media offers a novel approach to mitigating this issue. The electrochemical reaction and the presence of dissolved zinc ions influence the crystallization process of calcium carbonate. Instead of forming hard, adherent calcite crystals, the calcium carbonate is encouraged to precipitate as aragonite or other less problematic forms that are softer, granular, and less likely to build up as hard scale on surfaces. This significantly reduces maintenance needs and prolongs the life of pipes and appliances.

The physical characteristics of KDF 55 Media also contribute to its effectiveness. Available in various mesh sizes, such as the 5-100 mesh range, it provides a large surface area for reactions. While primarily known for its chemical and electrochemical actions, the media's granular nature also allows for some degree of physical filtration, capable of removing suspended particles down to approximately 50μm in diameter. This dual-action capability enhances the overall performance of water treatment systems.

KDF 55 Media is versatile in its application. It is commonly used as a pre-filter layer in multi-stage filtration systems, positioned before technologies like activated carbon, reverse osmosis (RO), deionization (DI), or ion exchange resins. When used in conjunction with activated carbon, KDF 55 protects the carbon bed from chlorine, allowing the activated carbon to focus more effectively on removing organic compounds, tastes, and odors. It is widely applied in point-of-use filters, such as shower filters for chlorine reduction and skin/hair health benefits, and in point-of-entry systems for whole-house water treatment.

Operating conditions for KDF 55 Media are generally flexible, making it suitable for diverse environments. Typical recommendations involve specific flow rates for optimal contact time and effective backwashing procedures to clean the media bed and remove accumulated contaminants or precipitated materials. It is effective across a broad pH range suitable for drinking water (typically 6.5-8.5) and can handle water temperatures ranging from 35°F to 212°F (1°C to 100°C), demonstrating its robustness even in hot water applications like showers.

The manufacturing process ensures a high-purity alloy, with the copper and zinc content consistently meeting rigorous standards (e.g., 99.8-99.9%). This purity is critical for the media's consistent performance and safety, particularly in drinking water applications where the release of undesirable substances is unacceptable. Rigorous testing confirms that the media itself does not introduce harmful levels of heavy metals or other contaminants into the treated water.
