As we all know, the tap water from ordinary household faucets is domestic water, which can not be directly used for drinking, and many people's practice is to boil the tap water and then drink it. However, boiling water is only a step of sterilization, and impurities of large and small particles in tap water cannot be eliminated by boiling. Then with the gradual improvement of the quality of life, people pay attention to the water purifier industry. After many versions of improvements, the water purifiers of various manufacturers have been able to effectively remove impurities and sterilize. People can directly choose to drink water from the water purifier.
So what means and technologies can the water purifier turn tap water into drinking water with such high efficiency? Let's share the water purification methods of the hot water purifier in the market. Let us all know how the water purifier works and whether the purified water can be directly drunk.
At present, the water purification process of hot-selling water purifier is mainly divided into three stages, which are also the most important three steps. First, the first stage is to filter the tap water. The material mainly uses microfiltration membrane or ppcotton to remove all kinds of visible substances, dust and impurities in the tap water. The sources of these particles are mainly from colloid, sediment, eggs, rust and secondary pollution of roof water tank. After removing the larger particles above, there will be some by-products from the disinfection of tap water. At this time, the second level of filtration is needed, usually made of compressed activated carbon or granular activated carbon to remove residual chlorine and some organic matters, and to absorb the color and smell of organic matters in the water. Then the third level of filtration is checked. The commonly used materials are ultrafiltration membrane or RO reverse osmosis membrane. This key primary filtration can effectively remove scale, heavy metals, bacteria, antibiotics and organic matters in water.
The above three steps are the core of the mainstream water purifier. Basically, after the above three-level filtration, there is no problem with the water quality. However, in order to make their own products better than others, manufacturers will also stick to the research of further filtering effect, and increase to level 4 or even level 5 filtering. For example, some of them will add another step of activated carbon filtration after RO reverse osmosis membrane filtration to improve the taste of water inlet. Although this step seems a bit weak, it is a dispensable step, but in this era of continuous improvement, it's worth praising that the manufacturer can control the last pass before the entrance. For example, in order to make consumers more comfortable drinking water directly filtered by water purifiers, some manufacturers creatively add a UV ultraviolet sterilization link to the tap. This link claims to be able to effectively avoid bacterial secondary pollution caused by filter elements and pipes, which is safe without side effects.
After the introduction of the water purifier, I believe you have a deeper understanding of it. At least we can clearly know the core filtration principle and the manufacturer's unique water purification scheme. In the pursuit of a higher life today, water purifier has gradually entered more and more people's families, as an effective tool to purify water quality, so that everyone can drink a cup of safe water more healthy, more secure and more convenient.
