After understanding their own water quality, friends can consider a water purifier suitable for their own.
Different water purification methods
Distillation: By heating water to the boiling point and then condensing and collecting water vapor, a purification method that leaves contaminants, can effectively remove bacteria, viruses, microorganisms and common chemical pollutants, including arsenic and barium , Cadmium, chromium, lead, nitrate, sodium, sulfate and many organic chemicals. However, some organic pollutants with boiling points lower than or close to water cannot be removed.
Note: Simply boiling the water can kill most bacteria and microorganisms, but it cannot remove common chemical pollutants such as lead, arsenic, nitrate, chlorine, etc., and due to the evaporation of heated water vapor, the content of the pollutants will be concentrated in a disguised form. Level.
Filtration: A purification method that adheres dissolved or suspended substances in water to the surface or voids of the absorption medium. The purification effect is related to the filter medium and water source pollutants. Generally, there are Microfiltration (microfiltration, The pore size is about 0.1 microns), Ultrafiltration (ultrafiltration, the pore size is about 0.01 microns), Nanofiltration (nanofiltration, the pore size is about 0.001 microns), the filtration effect is microfiltration
