What is the goal of purifying water quality in a household water purifier?

After the filter is rinsed, it removes chloride ions, heavy metals, some minerals and other impurities harmful to the human body, and meets the drinking water standard.

Destroys chemicals that are harmful to the human body and harmful microorganisms.

It's useless, boiling water, it's best to get cold.

Everyone generally has a misunderstanding of water purifiers, thinking that the water coming out of water purifiers is clean. In fact, after the tap water has been disinfected, it has met the hygiene standards, and most importantly, the tap water at this time contains a lot of minerals and trace elements, which are beneficial to the human body. (Although water alkali does not look good, it is actually produced by the precipitation of calcium and magnesium ions after heating, which is beneficial and harmless to the human body).

The function of the water purifier is to filter out all these minerals and trace elements, and the water produced is pure water (pure water), also known as "poor water". This kind of water is not suitable for long-term drinking, because it is impossible to supplement the necessary minerals and trace elements through water, and this water will also absorb the minerals and trace elements in the human body after drinking, so that the water itself can achieve a balance, and finally be discharged from the body, long-term drinking of this water is extremely harmful, especially if infants and young children only drink pure water for a long time, it will seriously affect physical development, manifested by late teething, physical retardation, weak physique, etc.

It's okay hot hot

The tap water purification process is divided into multiple steps such as pretreatment, gel aeration, sedimentation and sedimentation, filtration, etc., each step will play an important role in the quality of the water. However, the most ambitious step depends on the nature of the contaminants contained in the dusty land water and the specific conditions of the contaminated water. Typically, membrane filtration is one of the most purifying steps in the tap water purification process.

Because membrane filtration is a filtration method that physically isolates impurities, it can effectively remove fine suspended particles, organic pollutants, viruses and other pathogenic substances in water. The steps of pretreatment, gelling and sedimentation before membrane filtration are aimed at pretreating large particulate impurities, plankton, organic and inorganic substances in the water to reduce the water load in membrane filtration, thereby improving the efficiency and purification of membrane filtration. It should be noted that the quality and composition of tap water may vary in different regions and different water sources, so in the specific water purification process of tap tombs, which step has the highest degree of purification depends on the water quality situation, which needs to be analyzed and selected according to the local situation.

In the operation of purifying water, distillation is relatively high in a single operation.

In the distillation process, due to the different boiling points of substances, the substances volatilized at different temperatures are different, when the temperature is at the boiling point of water, only water becomes gas and volatilizes, and other substances do not change.

Therefore, distillation is a water purification method with a high degree of purification, and there are four main methods of water purification: static precipitation, filtration, adsorption, and distillation. The order of water purification in these four methods from low to high is: static precipitation, filtration, adsorption, and distillation.

Principles of Distillation:

The difference in the volatility of each component in the liquid mixture is used to partially vaporize the liquid mixture and subsequently condense the vapor part, so as to achieve the separation of the components contained in it. It is a unit operation that belongs to mass transfer separation.

It is widely used in oil refining, chemical industry, light industry and other fields. The principle is based on the separation of a two-component mixture. The liquid is heated to make it partially vaporized, the volatile components are enriched in the vapor, and the involatile components are also enriched in the residual liquid, which realizes the separation of the two components to a certain extent.

The greater the difference in the volatile capacity of the two components, the greater the degree of enrichment described above.

In industrial distillation equipment, the partially vaporized liquid phase is in direct contact with the partially condensed gas phase for vapor-liquid interphase mass transfer, and the result is that the refractory components in the gas phase are partially transferred to the liquid phase, and the volatile components in the liquid phase are partially transferred to the gas phase, that is, the partial vaporization of the liquid phase and the partial condensation of the vapor phase are realized at the same time.

Water purification is a series of physical, chemical and biological processes that remove contaminants from water to improve water quality. Here are some common principles and methods of water purification:

Filtration: Filtration is one of the most common methods of water purification. By using different levels of filter media (e.g. sand, quartz sand, activated carbon, etc.), suspended solids, soil, sand particles and most microorganisms can be removed from the water.

Activated carbon adsorption: Activated carbon is a porous material with strong adsorption capacity. It removes organic pollutants, heavy metals, chlorine, and certain harmful chemicals from water.

Precipitation: Precipitation is the addition of chemicals that allow contaminants to form water-insoluble solid particles, which are then removed by sedimentation or filtration. This method is commonly used to remove heavy metal ions and suspended particles.

Ozone treatment: Ozone is a strong oxidizing agent that can be used to kill bacteria, viruses and other microorganisms. Ozone can also degrade organic matter and remove odors from water.

Ultraviolet disinfection: Ultraviolet radiation kills microorganisms in water, such as bacteria, viruses, and parasites. This method is highly effective for inactivating microorganisms, but has limited ability to remove other contaminants.

Reverse osmosis: Reverse osmosis is a highly efficient membrane separation technology that filters dissolved solids, heavy metals, organics, and microorganisms from water through a semi-permeable membrane. The process involves applying water under high pressure through a membrane, allowing water molecules to pass through and preventing the passage of other substances.

Ion exchange: Ion exchange is the purification of water quality by exchanging ions in water with resin particles containing specific ions. This method can remove hardness substances (such as calcium, magnesium ions), lead, mercury, cadmium and other harmful bright ions in the water.

Biological treatment: Biological treatment is the use of microorganisms to break down and remove organic matter from water. Common biological treatment methods include activated sludge method, immobilized biofilm method, and constructed wetland method.

These methods can be applied individually or in combination to select the appropriate purification method based on specific water quality issues and needs. In practice, water purification systems often include multiple treatment stages to ensure that the water quality meets the specified standards.

Therefore, the answer is: sedimentation, removal of large particles of insoluble solid impurities; adsorption, removal of pigments and odors; filtration, to remove small particles of insoluble solids; Disinfection, removal of bacteria and viruses

The water of the reverse osmosis water purifier is pure, the kettle appliance is not scaled, no pollution, the taste is comfortable, and the original taste of tea and coffee is retained to the greatest extent. The use of reverse osmosis water purification can remove all kinds of harmful impurities in the water, including pesticides, fertilizers, and hormones, which can well retain the water molecules in the original water, ensure the safety of water quality, and avoid illness caused by drinking water.

Therefore, the use of reverse osmosis water purifier is safer, more economical, and more convenient and reassuring than bottled water.

Nowadays, RO reverse osmosis water purifier products have begun to gradually integrate into our lives, and a high-quality water purification product can bring support to all the safe water needs of families, and has been loved by many people who have a sense of crisis about water pollution.

Although Lisheng M8B is a RO reverse osmosis product, it has the function of double water outlet, which directly divides the water purification faucet into two, one side of the switch is the water outlet switch for domestic water purification, and the other side is the switch for pure water outlet. In this way, not only has a double outlet, but also has a guarantee of domestic water.

For water purifiers, the water output speed is a very important indicator, which is directly related to the user experience. The noun used by Wang Tang to determine the water velocity is called "flux", and the unit is "g", which is the "gallon" in Chinese. The first generation of water purifiers on the market has a flux of more than 400g, which is slower.

Over the years, with the upgrading of technology, the flux of water purifiers has also been continuously upgraded. The Lisheng M8B water purifier has a trapped slag flux of 800g - converted, it is about 2L min, and it can fill a glass of water in 5 seconds.

The general RO reverse osmosis water purifier wastewater ratio is 2:1, that is, 2 cups of purified water need to filter 1 wastewater. The water purifier brand with less wastewater in the industry is Lisheng M8B, which is one of the top ten ranking brands in the water purifier industry, and the wastewater ratio is 2:

1。It should be reminded that some manufacturers in the industry currently claim to have developed wastewater-free RO reverse osmosis water purifiers, but in fact, they are just hype, and consumers should not believe it.
