Water purifier technology in addition to RO reverse osmosis and ultrafiltration

Nowadays more and more households install water purifiers. Most people know about water purifier technology is activated carbon, RO reverse osmosis and ultrafiltration technology. However, nowadays technology is so developed, water purifier technology can not only these .

Magnetized water purification technology

Magnetized water appeared in the thirteenth century and was used in medical care. Until the last century, the Belgian Vemelang made an artificial magnetization device, and the magnetized water was only accepted by the world.

Magnetized purified water is produced by a magnetizer. The magnetizer is a structure in which a fluid magnetization device magnet is fixedly assembled, and the outer part is a metal shell, and the ends are high-density fine-machined nuts. When the water flows through the flow channel in the middle of the magnetizer, the physical structure of the mineral in the water changes due to the strong magnetic field, which reduces the heat and fouling of the clean water and acts like a soft water machine.

In addition, the magnetization inhibits the growth of bacteria in the water, causing the death rate of the water heterotrophic bacteria to be greater than the proliferation rate and playing a bactericidal effect.

Ultraviolet water purification by water purifier technology

UV sterilization has long been used in the food industry, often in food engineering and disinfection cabinets. In recent years, it has been found that specific wavelengths of ultraviolet light can kill bacteria in liquids and apply them to water purifiers.

Ultraviolet water purification technology uses ultraviolet photon energy to destroy various viruses, bacteria and other pathogenic DNA structures in water, causing various structural bonds in DNA to break or photochemically polymerize to achieve a sterilization effect. The ultraviolet water purifier usually has a built-in UV lamp, and the water flowing through the reaction chamber is sterilized by a short-wave ultraviolet light having a central radiation wavelength of 253.7 nm.

However, the UV lamp is a fragile device and needs to be replaced in time for its expiration. It should be noted that expired UV lamps can not only sterilize, but also promote the proliferation of pathogens.

Electrolytic water for water purifier technology

As early as the beginning of the last century, scientists from all over the world began to study the drinking water of the world famous Changshou Village, and the Japanese pioneered the development of water ionizers.

The biggest difference between electrolyzed water and other water purifier technologies is that electrolyzed water uses "electrochemical reaction" to separate positive and negative ions in water, thereby "manufacturing" weakly alkaline water instead of purifying harmful molecules in water. In addition, the electrolyzed water has a negative potential and is rich in active hydrogen, which can eliminate free radicals in the human body and play an antioxidant/aging role.

Electrolyzed water promotes raw drink, heating will promote the negative ionization of electrolyzed water and lose its effect, and the electrolysis water purifier must have pre-filtering means, and the electrolysis machine itself has no filtering effect.

Water purifier technology KDF clean water

Compared with the first three, KDF appears earlier and has a wider range of applications. Although KDF appeared very early, it was not certified by NSF until 1992 and was applied to the household water purifier industry.

KDF clean water actually uses different proportions of copper-zinc alloy to exchange electrons with oxidizing harmful substances in water through chemical reaction, turning harmful substances into harmless substances, and achieving certain bactericidal effects in the reaction process. Currently, KDF water purification materials on the market are classified into KDF55 (50% copper and 50% zinc) and KDF85 (85% copper and 15% zinc) according to the ratio of copper to zinc. Among them, KDF55 is more common, which can effectively remove chlorine and solubility in water. Heavy metal.

Previous investigations have pointed out that the output of the KDF water purifier has a zinc content exceeding the standard, which may have an impact on the human body. But overall, KDF is a better water purification solution.

We often say that "existence is reasonable", and online evaluation of these water purification technologies "smoke is greater than practical" is actually a prejudice. Although these water purification methods are not very popular now, they also have unique advantages. The water purification products are developing in a compound type. Who can conclude that these partial water purification technologies will not be widely used in the future?
