What are the components of a home whole house water purification system?

Household whole-house water purification system, is a home use tap water purification system, a high quality water demand and the existence of water purification program. Generally contains a pre-filter, central water purifier, central water softener, the end of the drinking water machine, or villa type will also be supporting the use of wall-mounted machines or vertical drinking machines. Water purification, is through the corresponding filter material, according to different final water demand, in a physical or chemical way, to remove rust, sediment, residual chlorine, organic matter, harmful heavy metal ions, bacteria, viruses and other processes in the water. Obviously, if the whole process of water purification uses physical filtration, it will not produce or add any new substances in the water, and it will not change the properties of the water, so it is the safest way, and it is widely used in the western countries nowadays. Of course, the more types of substances to be removed from the water, the more tiny the substances to be removed, the greater the demand for water purification per unit of time, the more advanced the filtration material to be invested in, the higher the cost of inputs, which is the price of different products of different grades, and the effect of the essence of the difference between the reasons.

Ordinary consumers often equate the purification of water at home with the purification of drinking water, and believe that home water purification products sold on the market can be used to solve the problem of drinking, the family's other living water without purification, this understanding is very limited. With the increasingly serious water pollution, a large number of organic pollutants and heavy metals through different ways into the water, drinking water sources are widely contaminated. In recent years, a variety of drinking water pollution incidents have been endless, such as: Harbin and Wuxi's water shutdown, is because of the organic matter in the water exceeds the standard, resulting in the tap water can not be used normally, human beings, if you use this kind of water, will lead to various types of diseases, based on the situation, the city of Harbin had to take a temporary water shutdown. It can be seen that the harm of organic matter in the water. In addition, the traditional water plant coagulation, filtration, chlorine disinfection process is to remove bacteria in the water, suspended solids, turbidity, chromaticity is the main, dissolved organic matter and heavy metals removal capacity is relatively weak, and chlorination disinfection itself has formed a "triple cause of the material" (carcinogenic, teratogenic, mutagenic), because the chlorine and organic matter reaction, the new synthesis of a number of harmful substances. For example, trichloromethane, these pollutants will be attached to the clothing, or directly absorbed through the skin, directly affecting the user's health.
