Look at your kettle. Is there a layer of gray scale on the bottom of the kettle? See if your faucets and showers are constantly clogged, or are the water flow slowing down and needing cleaning once a week? Scale not only affects the water experience, but also corrodes wading equipment and reduces the service life of wading equipment, so we need to clean it as much as possible.
First of all, we need to know how scale is formed. At high temperatures, calcium sulfate containing slightly soluble water will precipitate due to the evaporation of water, and carbonate in the water will combine with calcium and magnesium plasma , producing calcium carbonate and magnesium carbonate that are insoluble in water, that is, water alkali. As water continues to evaporate and concentrate, the alkali content of water continues to increase, and scale is formed after saturation.
Then, according to different formation causes and formation states, the structure is divided into hard scaling and soft scaling. When the water contains impurities such as carbonate colloids, bacteria and organic matter, the carbonate is like iron, while colloids, Bacteria and organic matter are like magnets. After carbonates are closely adsorbed by colloids, bacteria and organic matter in the water, they form hard scale on the walls of containers or pipes at high temperatures that is difficult to remove.
If sticky substances such as colloids, bacteria and organic matter are removed from the water, even if the concentration of carbonate ions and calcium and magnesium ions in the water is high, only loose, white, easy-to-remove carbonate soft scale will be formed.
Let's take a look at the function of pre-filter . The pre-filter is a coarse filtering equipment that can filter large particulate matter such as sediment, rust, eggs, red worms in tap water. Normal pre-filter The filter mesh precision is 40 microns, which can remove some precipitated impurities in the water and reduce the occurrence of scale. However, the pre-filter is powerless against carbonates dissolved in water. To completely remove scale, you need to use the pure water machine .
Many people may think that because the pure water machine can remove scale more thoroughly, there is no need to install a pre-filter. This idea is very wrong. The pre-filter can ensure that a large amount of precipitated impurities generated in the water supply pipe network are not It will cause harm to the human body, water softener , water purifier, pure water machine or direct drinking machine , solar water heater , electric water heater, gas water heater , washing machine and other water pipes and wading equipment installed on the water pipes. The device plays an active pre-protective role, in other words, the water purifier ensures the removal of scale in drinking water, while the pre-filter reduces scale in the water throughout the house.
