Purification of drinking water refers to the treatment of raw water (water supply) by using relevant water treatment technology or equipment according to the water quality indicators proposed by people to effectively reduce or eliminate some or all pollutants in water in order to obtain drinking water (including drinking water, cooking, soup making, ice making, etc.) that meets the requirements. 。

The effect of drinking water purification can be roughly divided into the following four categories:

1. If you want to remove sediment and improve the taste, then water purifiers such as activated carbon, fiber rural drinking water equipment or other filters can be solved. Such water purifiers can only block sediment and absorb some pollutants. These products need to replace filter materials regularly in ultrapure water treatment equipment. Otherwise, the deposition caused by blocking or adsorbing pollutants will pollute the subsequent filtered water.

2. If you want to remove water and alkali, you can solve the problem like a water purifier equipped with resin filter element of cationic school drinking water equipment. Because the resin can only absorb calcium and magnesium ions in water, and has no purification effect on other pollutants, it is safer to boil and drink such water.

3. If you want to remove sediment, rust and organic pollutants, and consider retaining such substances as water and alkali, you can use a water purifier with hollow fiber filter. Because the pore size of hollow fiber filter material is very small, it can block sediment and organic pollutants, but does not remove hardness ions, so consumers who have requirements for minerals in water can consider.

4. Remove not only water and alkali, but also all pollutants. Then a water purifier with reverse osmosis membranes can solve the problem. Because the pore size of reverse osmosis membrane is so small that only minerals below the diameter of water molecule and water molecule can pass through, other minerals such as bacteria, viruses, scales, heavy metal ions, organic pollutants and so on are blocked and discharged at the same time of filtration. Because there are still a small amount of minerals, it tastes sweet and can be directly drank raw.
