What is the difference between a pure water machine and a water purifier

We must all attach great importance to the issue of our domestic water use, especially when our water resources are becoming more and more polluted today, many families will buy water purification equipment to ensure that their water is healthy and pure. Water machines and water purifiers are the two most commonly used equipment. What is the difference between them and the water they have purified?

The concept of water purifier and pure water machine is different

The water purifier removes chlorine in urban tap water and bacteria, viruses, colloids, rust, impurities and other harmful organic pollutions that are harmful to the human body through the physical means of filtration and adsorption. The pure water machine intercepts all organic pollutants and inorganic ions in the water through RO membrane reverse osmosis with ultra-fine precision. There is a certain amount of waste water, and the effluent is pure water for direct drinking.

The characteristics of the water purifier and the pure water machine are different

In terms of characteristics, most water purifiers choose to use activated carbon, meltblown filter cores, microporous ceramics, hollow fibers, KDF, etc. to purify water. These materials need to be replaced regularly, and the filter element needs to be protected. The purification effect of the water purifier is good, but it cannot remove the calcium and magnesium ions in the water, that is, the problem of water alkali cannot be solved. The water purifier removes bacteria, viruses, colloids, rust, impurities and other harmful organic pollution to the human body, and can reduce the appearance of scale.

The advantages and disadvantages of water purifiers and pure water machines are different

The water purifier can remove harmful substances in the water, retain minerals and trace elements that are beneficial to the human body, and can be drunk raw without power supply and no waste water. However, water and alkali cannot be removed. If you want to remove it, you need to add configuration and replace the filter element. The impurity removal rate of the water purifier is as high as 96% or more, the taste is good, and the water quality is pure and sweet. However, waste water is generated during use, and the filter element needs to be replaced regularly. For every liter of water used, 3 liters or more of water needs to be drained. The water purifier completely purifies the water, so there is less water needed by the human body. Minerals and trace elements are not suitable for long-term use.

What is the difference between the water quality of pure water and purified water

The water from the water purifier retains most of the minerals in the tap water. The water coming out of the water purifier is equivalent to the pure water sold on the market, if you add medical stone, it is roughly equivalent to mineral water.

The above are the differences between water purifiers and water purifiers and the water quality they produce. I hope you can understand that if we need to buy water purification equipment in the future, it’s best to follow the actual local water quality. Choose the appropriate water purification equipment to use.

Comparison of several different types of domestic water heaters

Regarding the selection of our many domestic water heaters, the situation of each household is different, so the suitable water heater types are also different, so how can we choose the right water heater when we choose the water heater? Today, I will introduce several different types of water heaters for everyone to choose in the future.

Domestic water heater classification-electric water heater

According to the heating power, electric water heaters can be divided into three types: water storage type (also known as volumetric or heat storage type), instant heating type, and quick heating type (also known as semi-storage type); water storage type is the main form of electric water heater According to the different installation methods, it can be further divided into vertical, horizontal, floor-standing, trough-under, and the latest integrated design integrated with bathroom cabinets. It can be divided into open type (simple type) and closed type (pressure type) according to whether it is under pressure or not. According to the usage, it can be divided into household and commercial.

Domestic water heater classification-gas water heater

The basic working principle of the gas water heater is that cold water enters the water heater, flows through the water-air linkage valve body, under the action of a certain pressure difference of the flowing water, pushes the water-air linkage valve, and at the same time pushes the DC power micro switch to turn on the power and start the pulse The igniter, at the same time, open the gas solenoid valve, and continue to automatically re-ignite through the pulse igniter until the ignition is successfully entered into the normal working state, and this process will continue for about 5-10 seconds.

Domestic water heater classification-solar water heater

Solar water heater is a device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet people's hot water use in life and production. According to the structure, solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters, mainly vacuum tube solar water heaters, occupying 95% of the domestic market share. Vacuum tube domestic solar water heaters are composed of heat collection tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly relies on vacuum heat collection tubes. The vacuum heat collection tubes use the principle of hot water floating and cold water sinking to make the water produce micro-circulation. Reach the required hot water.

Domestic water heater classification-air energy water heater

Air energy water heater, also called "air source heat pump water heater". The "air-energy water heater" absorbs the low-temperature heat in the air, is vaporized by the fluorine medium, and then compressed by the compressor to increase the temperature and increase the pressure, and then is converted to the water for heating by the heat exchanger, and the compressed high-temperature heat is used to heat the water temperature. Air-energy water heaters have the characteristics of high efficiency and energy saving. They produce the same amount of hot water, which is 4-6 times that of electric water heaters. Its annual average heat efficiency ratio is 4 times that of electric heating, and its energy efficiency is high.

The above are some of the different types of domestic water heaters introduced by the editor. You can refer to them. When we buy and use water heaters in the future, we can refer to the above several types of water heaters, so as to help us choose the most suitable for us. Domestic water heaters bring us a comfortable life experience.

Advantages and comparative analysis of household reverse osmosis water purifiers

When it comes to water purifiers, everyone is no stranger, and almost all of our households have water purifiers installed. However, a new water purification product, a reverse osmosis water purifier, has recently appeared on the market. For new products, many people are skeptical: Is the household reverse osmosis water purifier good? Okay, let’s not talk about it here. Let me explain the advantages of household reverse osmosis water purifiers compared with other products.
The market water purifiers should be five-stage filtration, the first stage is PP cotton filter element, the second and third stages are granular activated carbon, the fourth stage is RO reverse osmosis membrane, and the fifth stage is post activated carbon, which is mainly used for Improve taste. The filter element of the household (commercial) water purifier has a service life. The fiber filter element can generally be used for 6 months, and the activated carbon filter element is generally 12 months. Their life span depends entirely on the local water quality, water pressure and water consumption; In the case of regular replacement of the filter element, the shelf life of the reverse osmosis membrane is 2 years. If the pretreatment is sufficient, the actual service life can reach 8 years, and the removal rate can reach more than 99%. The pure water produced by the water purifier can be used not only for daily drinking, but also for making tea, coffee, milk powder, refrigerated drinks, etc., direct raw drinking effect is better, using pure water to make ice cubes crystal clear, clean and hygienic, pure water It can be used for steaming rice, soup, porridge, etc. The taste of the prepared food is pure. When you need to eat raw fruits and vegetables, it is best to wash the last time with pure water. It is more assured to eat. Pure water will not irritate the skin. Washing your face can play a cosmetic role.

Compared with bottled water: Although the pure water of the reverse osmosis water purifier has the same quality as the bottled water, compared with the bottled water, the reverse osmosis water purifier still has some advantages: there is no bottled water to order water, etc Water, water change and other issues. The water quality is fresh, sweet and delicious. The cost of water production is less than RMB 3 per barrel (5 gallons). Cooking rice is more fragrant, soup is more delicious, tea is more sweet, and washing face is brighter...

Contrast ultrafiltration machines: Household reverse osmosis water purifiers, both reverse osmosis water purifiers and ultrafiltration membrane water purifiers, can provide us with clean water, and they are both household water purification equipment worth looking forward to. Reverse osmosis water purifiers and ultrafiltration membrane water purifiers also have their own characteristics. There are different options for different water quality conditions. For example, the water quality of the source water is very good: the ion content in the water body is very small (TDS is less than 50mg/L), and the water body does not contain harmful substances such as heavy metal ions that are harmful to the human body. This will be your choice. Because ultrafiltration membrane water purifiers have the following advantages over reverse osmosis water purifiers: low energy consumption and high water utilization. If the source water quality is not very good or there are uncertain factors, then from the perspective of drinking water safety, a reverse osmosis water purifier will be your best choice. Because the reverse osmosis water purifier can always provide you with high-quality pure water.

Is the reverse osmosis water purifier good? After reading the above introduction, do you know it? Whether a product is good or not is not determined by one or two people, but by its quality and effect. The multiple filtering effects of reverse osmosis water purifiers not only make our drinking water safer and healthier, but also make our lives more comfortable and convenient. If your home has not installed a water purifier, buying a reverse osmosis water purifier is a good choice for you.

Which exhaust gas water heater is better

Gas water heater is an early and mature water heater. Now, many other types have been introduced in the most traditional water heater type. Which gas water heater is better? For the forced exhaust type, flue type, and balanced type that are classified according to the exhaust mode, which one is better? Let's make a detailed comparison below to see which one is more ideal.
The flue gas water heater discharges the exhaust gas after combustion to the outdoors by virtue of the principle of air dynamics. If the user closes the doors and windows while taking a bath, the exhaust gas generated by the water heater cannot be effectively discharged outdoors, which can easily cause a safety accident. The current price of this gas water heater is relatively low, but the safety guarantee is not very good. Therefore, if users want to install, they must pay attention to the simultaneous installation of the smoke exhaust pipe, and install it strictly and use it reasonably. Now this gas water heater has gradually withdrawn from the market.
Compared with the flue type, the "forced exhaust" gas water heater is more reliable in exhausting smoke. The mainstream gas water heater products currently on the market are mostly "forced exhaust type". However, this type of gas water heater is best installed in the kitchen or balcony, because the oxygen is taken indoors, and when working, it may cause the flue to be blocked and the carbon monoxide content will increase.

Balanced gas water heater is currently the safest gas water heater. Compared with the previous two types of water heaters, the biggest difference of the balanced gas water heater is that it can form a sealed system isolated from the indoor air together with the supporting flue, that is, it does not consume indoor air or cause smoke pollution. Balanced gas water heater is currently the most ideal type of gas water heater, but it is also the most expensive one at present. Balanced gas water heaters are the only ones allowed to be installed in bathrooms according to national standards. Balanced water heaters are the development trend of water heaters and also the trend of international water heater development. It is safe to choose to install the balanced gas water heater in the bathroom.

Which gas water heater is better? Through the above comparison, we can find that each gas water heater has its own advantages and disadvantages, etc. When users choose and use, they must pay attention to the comparison in terms of safety, and at the same time, they should also combine their own economy. Starting from the situation, after comparing various aspects, you can choose a gas water heater that is more satisfactory to you.

Comparative analysis of direct drinking machine and drinking machine

In our family life, our most important demand is drinking water, the safety of drinking water has a great impact on our health. The two better devices used by families are direct drinking machine and water dispenser. Which one is better? Today, let's analyze and compare these two kinds of equipment for you to understand.

As the name suggests, it is a kind of machine and equipment to purify water directly and then reach the three standards of direct drinking water. Direct drinking water machine is a kind of water appliances, through multi-stage purification, into the high-tech components, so that the water molecules, weak alkali, so that the family tap water can achieve the effect of direct drinking, so that the human body is more easily absorbed, and can achieve the role of regulating the body acid-base balance.

Working principle: reverse osmosis technology is mostly used in purified water machine: the principle of reverse osmosis is to exert a greater pressure than the natural osmotic pressure on the raw water side, so that the water molecules reverse osmosis from the high concentration side to the low concentration side. As the pore size of reverse osmosis membrane is far smaller than that of case virus and bacteria by hundreds or even thousands of times, all kinds of viruses, bacteria, heavy metals, solid soluble matter, polluted organic matter, calcium and magnesium ions can not pass through reverse osmosis membrane at all, so as to achieve the purpose of water softening and purification.

1. Safety performance the water dispenser is powered by power supply. If the water dispenser has electric leakage and poor insulation, it is extremely dangerous. Consumers should first recognize the brand of the product and the CCEE product certification mark of China Electrical Safety Certification Committee.

2. Electrical performance water injection, power on, press the refrigeration and heating power switch several times, the switch contact should be good, the corresponding indicator light will be displayed, indicating that the circuit of the water dispenser is basically normal. Press the refrigeration switch, use your hand close to the air outlet of the back plate, there is a sense of exhaust, you can't hear the noise, the noise is very weak, and the fan operates normally. After 2 hours of power on, press the refrigeration faucet, cold water should flow out. For example, semiconductor refrigeration can reduce the temperature of ice water to 5-15 ℃, and compressor refrigeration can reduce the temperature of ice water to 4-12 ℃. Press the heating switch and heat for 15-20 seconds. The water temperature should reach 92-96 ℃. During this period, the heating indicator will turn on and off automatically.

3. When the water is poured into the water dispenser for disinfection and descaling, a large number of bubbles will be brought in, and these bubbles will carry some bacteria into the barreled water. On the other hand, if the water dispenser is used for a long time without cleaning, the water tank, water channel and water outlet will deposit dirt and breed a large number of bacteria. After using for a period of time, the water dispenser must be cleaned, disinfected and descaled regularly to ensure people's healthy life. Water dispenser cleaning, must use qualified cleaning agent and professional water dispenser cleaning tools.

The above is to introduce some differences and advantages of direct drinking machine and water dispenser. You can refer to it. In our life, it's better to choose and decide which equipment is more suitable for you according to your actual situation. At this time, it's the best to choose.
