answer 2:

The types of filter elements of

water purifier mainly include the following:

1. PP filter element

PP filter element is generally low in price, but it is easy to jam and needs to be replaced frequently. The filtration accuracy of PP filter element is not high, and it is only used for preliminary filtration of water.

2. Activated carbon filter element

activated carbon filter element is divided into two categories: granular activated carbon filter element and compressed activated carbon filter element. The former has unstable service life and effect, and is often used as secondary filtration of various household water purification equipment. The latter has a longer service life and is often used as the tertiary filtration of various household water purification equipment.

3. The filtration accuracy of reverse osmosis filter element

reverse osmosis membrane is 0.0001 μ

answer 3:

The filter element of the water purifier is to purify the water containing impurities to the cleanliness of the sanitary standard of drinking water, remove solid particles such as sediment and rust, filter bacteria and viruses, and absorb harmful chemical components such as heterochromatic odor. The types of filter elements used in water purifier vary according to filtration accuracy and requirements: activated carbon filter elements include compressed activated carbon filter elements and granular activated carbon filter elements. 1. Compressed activated carbon filter element, such as Franny pure natural coconut shell sintered activated carbon 2. Granular activated carbon filter element, put the required activated carbon particles into a special plastic shell, weld the end cover on the two end faces of the shell with welding equipment, and put non-woven fabric filters for filtration at both ends of the shell to ensure that carbon powder and black water will not fall from the carbon core during use. PP filter element PP filter element is also called PP melt blown filter element. The melt blown filter element is made of polypropylene ultra-fine fiber hot-melt entanglement. The fiber randomly forms a three-dimensional microporous structure in space. The pore diameter is gradient distributed along the filtrate flow direction. It integrates surface, deep and fine filtration, and can intercept impurities with different particle sizes. Market applications mainly include 5umppf and 1umppf. In the water purifier, it is mainly used for the first stage filtration to filter large particle impurities such as sediment and rust in the water. Ceramic filter element ceramic filter element is a new type of environmental protection filter element, which is prepared by using diatomite mud as raw material and special molding method. It is generally used for the tap of water purifier, and the filtration accuracy is generally 0.2 μ m。

answer 4:

carbon fiber (ACF) activated carbon fiber filter element; activated carbon fiber, a kind of carbon fiber (such as phenolic based fiber, PAN based fiber, viscose based fiber, asphalt based fiber, etc.) is activated at high temperature (different activation methods have different activation temperatures), resulting in nano pore size on its surface, increasing specific surface area, and changing its physicochemical properties.

Features: compared with the traditional adsorbent granular or powdered activated carbon, activated carbon fiber has excellent structure and performance characteristics. ACF fiber has fine diameter, large specific surface area, developed microporous structure, small pore size and narrow distribution, large adsorption capacity, fast absorption and desorption speed and easy regeneration. The traditional activated carbon is a kind of activated porous carbon, which is powdered or granular, and Activated carbon fiber is fibrous and covered with micropores. Its adsorption capacity for organic gas is several times to dozens of times higher than that of granular activated carbon in air, 5 ~ 6 times higher in aqueous solution, and the adsorption rate is 100 ~ 1000 times faster. (for example, the website link of active carbon fiber composite filter element produced by Danjiangkou Puluo e-mail Technology Co., Ltd.)

Function: ACF has large adsorption capacity, fast adsorption speed and high purification efficiency for various organic and inorganic gases and organic and precious metal ions in aqueous solution. It has excellent adsorption performance for low concentration substances
