What exactly is "KDF" in water purification equipment?

August 13, 2020

Many consumers always hear the word "KDF" when they purchase water treatment products. Many people do not understand it. What exactly is KDF and why should it be promoted? Is it safe? Today's editor took everyone to know about KDF filter media, and see what kind of benefits it has!

What is the KDF often heard in water treatment products?

The “KDF” that we usually hear is actually a kind of filter material in the water purification equipment. This KDF water treatment company's patented copper-zinc filter is a high-purity copper/zinc alloy, which is electrochemically oxidized. The reduction (electron transfer) reaction, which effectively reduces or removes chlorine and heavy metals in water, and inhibits the growth and reproduction of microorganisms in water, is currently an ideal water treatment method.

What are the benefits of water pretreatment with KDF?

Water pretreatment with KDF is a simple, low-cost method. It protects expensive and fragile water treatment components from the effects of chlorine, microbes, and scaling. Compared with microfiltration, ultrafiltration, reverse osmosis membranes, ion exchange resins and granular activated carbon, KDF has more advantages in terms of improving water treatment efficiency and maintaining high efficiency, and consumes less. Today, KDF has been widely used in the international market from kitchen faucets to industrial cooling water treatment.

1. Reduce mineral scaling

KDF treatment medium can prevent the formation and accumulation of mineral hard scale, mainly to prevent the crystallization of calcite form calcium carbonate.

2. Reduce suspended solids

KDF55 filter media effectively removes particles as small as 50 μm in diameter, preventing them from entering the body.

3. Remove oxidants in the water (free chlorine)

The water in Shanghai always has the smell of bleach because it contains residual chlorine, which generates the potential carcinogen--trichloromethane, and can cause many diseases in the body. KDF55 can effectively remove residual chlorine and other oxidants in water.

4. Inhibiting the reproduction of microorganisms and controlling the growth of microorganisms

5. Remove heavy metals and hydrogen sulfide

In life, what are the general KDF applications?

Suitable for chlorine-treated municipal tap water. Including residents, businesses, schools, utilities and light industry, construction sites, and factories that use tap water.

Is KDF safe? Is there any harm to the human body?

KDF Water Treatment Company has a history of 22 years so far and is a leader in the water treatment industry. KDF's patented copper-zinc filter is widely used in various industrial production processes of water treatment, and can be recycled without any additives and can be used safely. The use of the equipment in hospitals, hotels and various utilities water treatment equipment.

The KDF55 treatment media meets the requirements of the U.S. Environmental Protection Agency (EPA), the Federal Drug Administration (FDA), the Water Quality Association (WQA), and the National Sanitation Foundation (NSF) standards for the highest levels of zinc and copper in drinking water, such as KDF processing. The medium can remove 10 ppm of chlorine in the water, but it still meets the EPA's regulations for maximum allowable zinc in drinking water. Therefore, it is safe to apply.

Editor's note: General technology, can only be selected based on the size of the material particles, remove all large, or remove a range of particles. KDF can effectively solve the problem of heavy metals and retain beneficial substances. This benign choice is not available in many technologies. KDF features long life and repeatable use. At present, there are many similar products in the market, but the quality is uneven. Therefore, when consumers purchase water treatment products, they should pay attention to whether it uses genuine KDF filter media to ensure the effective purification of water quality.
