Overview of Central Water Purifier 　　The central water purifier is equipped with KDF filter material and advanced activated carbon through a reasonable and scientific configuration. By integrating core technologies such as physical adsorption, filtration, and microelectrochemical electric field, it can efficiently remove residual chlorine, heavy metal ions, inhibit bacteria and scale, and improve taste, color, and flavor. This not only removes harmful substances from the effluent, but also retains trace components that are beneficial to the human body, improving the quality of life and becoming a popular choice for healthy water among consumers. Working principle of central water purifier 　　The central water purifier is mainly composed of KDF filter material, ultrafiltration membrane, coconut shell activated carbon, activated balls, mineralized balls, etc. The core part is the high-purity copper and zinc alloy filter material produced in the United States by KDF (Kai De Fei). KDF filter material effectively reduces or removes chlorine and heavy metals in water through electrochemical oxidation-reduction (electron transfer) reactions, and inhibits the growth and reproduction of microorganisms in water. The micro primary battery formed by the different electrode potentials of copper and zinc is the key to purifying water with alloy filter media. The principle of the primary battery further activates zinc, allowing it to react with residual chlorine, iron, and various heavy metals in water, thereby removing these harmful substances. Process flow of central water purifier

The central water purifier is divided into two processes: working process and backwashing process
working process
　　Tap water → Multi way valve inlet → KDF → Activated carbon → Lower distributor → Central pipe → Multi way valve outlet → Water point
　　In this process, tap water first passes through KDF filter material to remove impurities, suspended solids, and most of the residual chlorine, heavy metals, hydrogen sulfide, etc. in the water, and inhibit the growth of bacteria, and then enters activated carbon. Activated carbon further adsorbs and filters small organic matter, residual chlorine, heavy metals, etc. in water, and decolorizes and deodorizes water quality to improve its taste.
Backwashing process
　　Tap water → Multi way valve inlet → Central pipe → Lower water distributor → Activated carbon → KDF → Multi way valve waste outlet → Drainage pipe
　　After a period of water purification operation, impurities and colloids will cover the surface of KDF, and activated carbon will also reduce its efficiency due to the adsorption of a large amount of impurities. Therefore, regular cleaning of KDF and activated carbon is necessary. In the backwash state, KDF and activated carbon will float up and, under the action of water flow, carry away the sediment, exposing a fresh surface, thereby restoring their function.

How to choose a central water purifier 　　With the continuous rise of the water appliance industry, the prospects of central water purifiers in the future market are very optimistic. But how to choose a central water purifier is very important. Below are several methods for your reference:
·The material of the water purifier must be non-metallic, as metal products can corrode and cause secondary pollution when in contact with water for a long time.
·Choose a central water purifier that meets the national drinking water standards and check if it has a national testing report.
·When choosing water purification products, please consult professionals in detail before purchasing the central water purification product that suits you.
·The performance of the central water purifier includes design principles, backwashing effect, filter material usage cycle, water flow rate, environmental protection, whether there is secondary consumption, and strives to achieve high quality and low price.
·To choose a manufacturer with a good corporate reputation, high-quality product quality, and a comprehensive after-sales service system.
·When choosing a water purifier, it is best to have advanced filter materials such as KDF and ceramic balls that are currently internationally recognized, rather than some other filter materials that have not been certified by the country. This is the only way to ensure water safety.
·Choose the appropriate central water purifier based on the functional characteristics of different water purification products, as there is no universal product that can meet the purification needs of various water qualities.
