While the industrial revolution has promoted social development, it has brought serious consequences - environmental pollution, especially water pollution. Water is the source of life, and no creature can survive without water. The harm caused by water pollution is closely related to human health. Most of the world's river waters are seriously polluted by industrial development. There are decontamination and secondary pollution in the tap water supply system. With the traditional water purification method, it is difficult to ensure the safety of water quality.
In order to solve the problems brought by water pollution to human life, all countries in the world have invested huge sums of money to control polluted waters, but only long-term maintenance and management will be effective, and people's living water security is urgent. Therefore, household water purifiers began to gradually enter thousands of households, providing a solid security for our domestic water.
The water purifier is actually the general name of household water purification equipment. According to the standard of filtration accuracy, it is generally divided into two categories, RO machine (pure water machine) and ultrafiltration machine. At present, according to the standard RO machine on the market, PP cotton, granular carbon, compressed carbon, RO membrane (reverse osmosis membrane) and post-activated carbon 5-stage filtration system are usually used. The market standard for ultrafiltration machines is similar, mainly because of the different membranes used, PP cotton, granular carbon, compressed carbon, ultrafiltration membrane, and post-activated activated carbon 5-stage filtration system.
The water purifier is the guarantee of every drop of healthy water. When purchasing the water purifier, we should choose the water purifier with different filtering functions according to different water quality.
1. In the northern part of China, the hardness of water is higher, and in areas with karst landforms in the south, the high content of calcium and magnesium ions in the water forms a harder water quality. Such hard water is very easy to scale. It is best to add a soft water machine in front of the household water purifier to deal with hard water, which can soften the water and play a certain protective role on the water purifier.
2. For urban and rural tap water, because it contains more chlorine and organic matter, the water quality and odor are heavier. Such water quality should choose household water purifier products with more filter activated carbon load.
3. If the water quality is in a relatively turbid tap water for a long time, it should be installed with a pre-cleaner in front of the water purifier. After primary filtration, most of the macromolecular substances are filtered out, which reduces the difficulty of the water purifier and can be extended. The life of the filter element.
4. If the heavy metal content in the water is high, the RO machine must be selected because the diameter of the heavy metal ions is mostly smaller than the filtration pore size of the ultrafiltration membrane, and can pass through the ultrafiltration membrane along with the water molecules. Only the pore diameter of the RO membrane is 0.0001 micron. It can prevent the removal of substances outside the water molecules and thoroughly purify the water.
