Nowadays, people pay more and more attention to the safety of their drinking water, so many families have just started to use water purifiers. The water purifier can remove the residues in the water, and the auxiliary parts that play a leading role are Water purification filter element 。 So, everyone is right Water filter element How much do you master? What is its structure? Now let's introduce to everyone.
Structure of water purification filter element and its removal method
The filter element of the water purifier is generally full of KDF and its activated carbon. The filter element is used to clean the water polluted by the environment to the level necessary for production, manufacturing and daily life, that is, to make the water reach a certain cleanliness level. Remove solid particles in water, eliminate germs and filter out harmful ingredients.
How is the structure of water purification filter element
The first layer of PP cotton: PP cotton is one of the indispensable filter elements in the water purifier. It can reasonably filter the sand, rust and other large particulate chemicals in the water. It is also the filter element that is most often replaced in the water purifier. PP cotton filter element is made of chemical fiber made of polypropylene resin and coiled and bonded by the chemical fiber itself. The structure of the filter element is a gradual tightening structure with thick chemical fiber on the surface layer and fine chemical fiber on the inner layer. The surface layer is loose and the inner layer is inseparable. Filter from the outside to the inside. The closer to the inner layer of the filter element, the smaller the diameter, the higher the filtration precision. The distinctive gradient direction of deep filtration has produced a three-dimensional practical effect of impurity removal, which has the characteristics of high porosity, high closure rate, large sewage holding capacity, large flow rate and bottom pressure drop.
The second layer of activated carbon: the most common particles in the water purifier are coconut shell activated carbon (UDF), calcined activated carbon filter (CTO), also known as carbon rod filter shrinking activated carbon filter, and rear camera activated carbon (T33). Generally speaking, activated carbon is made from wood carbon, bamboo carbon, various fruit kernels and high-quality coal by crushing, sieving, metal catalyst activity, soaking, air drying and selecting a series of technological processes based on physics and organic chemistry. It has the two-way characteristics of physical absorption and organic chemical absorption, It can selectively absorb various chemicals in drinking water to achieve the purpose of fading, deodorizing, and removing organic chemical environmental pollution and volatile organic compounds.
The third layer of KDF filter element: KDF is a kind of filter material for sewage treatment developed by KDF Sewage Treatment Company of the United Kingdom with new upgraded technical products. It is a high-purity copper zinc alloy. The actual effect of removing permanganate index is remarkable, and the working capacity of removing permanganate index is ten to dozens times of that of activated carbon; It has strong removal effect on heavy metal ions; It has a certain scale prevention efficiency; Inhibit the breeding of bacteria and algae in the water; Long service life. A small amount of metal oxides will be generated in the water where the whole process of KDF redox reaction is basic, and the resulting calcium/magnesium precipitation must be eliminated when necessary. Therefore, we'd better choose the one with backwashing effect in the whole process of selecting this type of water purifier, so that we can remove all the waste remaining on the KDF surface.
Above is the structure of the filter element of the water purifier introduced in detail for everyone. The filter element of the water purifier has a double-layer structure, and the water purifier relies on this chemical substance in the filter element to carry out water filtration. There are also many famous brands of water purification filter elements. We can shop around and choose the water purification filter element of the famous brand we like.
