Talking about the difference between pure water machine and direct drinking machine

Water quality has become a big problem in today's society. In order to improve the water quality, there are many products, including pure water machine and direct drinking machine. What is the difference between these two products? Next, I'll give you an answer. Let's talk about the difference between the pure water machine and the direct drinking machine. Let's look at it together.

The difference between pure water machine and direct drinking machine

The direct drinking machine is a kind of device which can purify municipal tap water into direct drinking water, or at the same time, it can heat, cool and distribute the purified water by consuming electric energy.

Water purifier is a kind of water purification equipment which uses multi-stage filter element to purify water quality. The physical methods such as filtration, adsorption and reverse osmosis without adding chemical substances are used in the treatment. According to the water purification accuracy of water purifier, it can be divided into drinking water purifier, also known as household water purifier and laboratory water purifier which can meet the requirements of laboratory pure water quality.

Difference between pure water machine and direct drinking machine - different advantages

The water in the direct drinking water dispenser is purified and reaches the standard of direct drinking water. For example, the direct drinking water machine of runsuo in the United States adopts reverse osmosis low-pressure RO membrane filtration treatment. The purified water after treatment is fresher, safer and more hygienic than barreled water, which is also one of the biggest advantages of the direct drinking water machine. Direct water dispenser has strong water supply capacity. If you want to drink hot water and warm water, you can drink it at any time as long as the temperature is enough, which is simple and convenient. Direct drinking water dispenser will automatically cut off power when encountering electric leakage and other dangerous situations, so it is safer to use.

With RO reverse osmosis membrane as the core filter element, the water purifier has a filtration accuracy of 0.0001 μ m (1 mm = 1000 μ m), which can remove 100% of the secondary pollutants such as rust, colloid, organic matter, bacterial virus and other macromolecular substances in tap water due to pipe aging and water tank pollution. Only a small part of water molecules can pass through the filtration membrane to completely purify the water quality, Truly achieve pure effect. Generally, purified water will be equipped with pre activated carbon, post activated carbon and other filter elements to deeply purify, absorb impurities, and improve the taste, so as to drink more mellow directly.

Through the above description, we can better understand the difference between pure water machine and direct drinking machine, which will help people better choose their own products. We can know the difference between pure water machine and direct drinking machine through other ways. Because there are many products in today's society, it is very necessary to understand the differences between them.

Advantages and differences between pure water machine and ultrafiltration machine

The water purifiers and ultrafiltration machines that we will introduce today are the most mainstream products on the market. Their most important filter elements are filter elements and reverse osmosis technology. As a member of the water purification system family, what are their differences and advantages? In fact, the water purification system also includes water purifiers, central water purifiers and so on.

The difference between pure water machine and ultrafiltration machine-ultrafiltration machine

principle

Ultrafiltration is a pressurized membrane separation technology that allows small molecular solutes and solvents to pass through a special membrane with a certain pore size under a certain pressure, so that macromolecular solutes are impermeable and stay on one side of the membrane. Macromolecular substances have been partially purified. Ultrafiltration can be divided into three types: microfiltration, ultrafiltration and reverse osmosis according to the operating pressure applied and the average pore diameter of the membrane used. The operating pressure used by reverse osmosis is greater than that of ultrafiltration, often reaching 35×10^5 Pa～140×10^5 Pa. The average pore size of the membrane is the smallest, generally less than 10 angstroms. It is used to separate small molecular solutes, such as seawater desalination. , High-purity water, etc.

advantage

No waste water, no electricity, water can be discharged by tap water pressure, convenient and simple to use. At present, ultrafiltration membrane water purifiers are widely used in the south, especially in places with low scale. At the same time, water purifiers are also used as water purifiers for units, schools, banks, etc. These water purifiers are more effective, safer and more reliable to use, and ensure healthy drinking water.

Disadvantage

Incomplete filtration. If the water contains heavy metals and toxic and harmful substances, the ultrafiltration membrane will not filter thoroughly. At the same time, the problem is that the ultrafiltration membrane produced by some small manufacturers is of poor quality and it is difficult to guarantee the filtration effect. The membrane pores are not uniform. The filtering problem is also very serious.

The difference between pure water machine and ultrafiltration machine-pure water machine

principle

It is to filter the floating matter in the water, heavy metals, bacteria, viruses, etc. are removed. It has a higher filtration technology. Household water purifiers generally use four or five levels of filtration. The first level is a pp cotton filter element, and the second level and The third grade is activated carbon (a well-made manufacturer can combine the second and third stages into one), the fourth grade is RO reverse osmosis membrane, and the fifth grade is precision activated carbon, which is mainly used to improve the taste, so pure water machine comparison Suitable for areas with more serious tap water pollution.

advantage

Due to the small membrane pores, the filtration is thorough, which can effectively remove impurities, bacteria, viruses and other harmful substances in the water, and at the same time remove all heavy metals. The quality of the water coming out is pure water with better taste, which is widely used in medical and sanitation industries.

Disadvantage

The amount of waste water is large, electricity is required, and the installation is relatively complicated and troublesome. Because the water purifier adopts multi-stage filtration, the auxiliary filter element is frequently replaced, which causes the cost to rise, and it is easy to breed the hidden danger of secondary pollution. It is difficult to use a water purifier as a whole-house water purifier or a central water purifier because of its low water quality and flow rate, so the water purifier works better.

In addition to the filter elements of the two types of water purifiers introduced in the article today, other water purifiers such as ceramic filter elements are actually forbidden to be used abroad, because the filtering effect is not good, the cost is not high, and it is difficult to meet the water quality requirements. So if you want to buy a water purifier, you can use today's article as a reference.

The difference between water purifier and water softener

Water treatment equipment includes many types, including water softeners, water purifiers, and water purifiers. At the same time, they also perform their duties and each have their own specialties. Today, I will give you a brief introduction to the water purifier and water softener. What are the differences between water purifiers and water softeners, which are also water treatment equipment, and where are their respective areas of responsibility, can they replace the existence of one party? The following explains the difference between water purifiers and water softeners in detail!

Different structure

Water purifiers can be divided into vertical ultrafiltration water purifiers and horizontal ultrafiltration water purifiers according to different installation methods. The vertical ultrafiltration water purifier is composed of PP cotton, granular activated carbon, compressed activated carbon, external pressure ultrafiltration membrane, and T33; the horizontal ultrafiltration water purifier is composed of a stainless steel shell, an internal pressure ultrafiltration membrane, and KDF. The water softener is mainly composed of: multi-way valve controller, resin tank, strong acid cation exchange resin, water distributor, salt valve, salt tank, etc. The materials and structures of water purifiers and water softeners are very different, which leads to differences in the objects and scope of their use.

Different use

The water purifier is a Zhengzhou water treatment equipment that filters bacteria and impurities in the water. The main target of removal is: floating substances, heavy metals, bacteria, viruses, etc. As for water softeners, they are much simpler. Water softeners are Zhengzhou water treatment equipment used to soften water. They target hard water and target the magnesium and calcium ions contained in hard water.

Different working modes

The water purifier uses five-stage filtration technology to process water into water that can be used for human consumption. The five-stage filtration is: the first stage is a filter element, also known as PP cotton; the second stage is granular activated carbon; the third stage is precision compression Activated carbon; the fourth grade is reverse osmosis membrane or ultrafiltration membrane; the fifth grade is post activated carbon, mainly used to improve taste. Compared with the water purifier, the water softener also uses five processes to achieve the water purification function and soften the hard water. The five processes are divided into: work (sometimes called water production), backwash, salt absorption (regeneration), slow flushing ( Replacement), fast flushing five processes.

The above is the difference between a water purifier and a water softener. The difference between the two types of water purifiers is very big. Carry out a detailed investigation of the water quality and purchase water treatment equipment under the guidance of professionals.

What are the types of straight drinking machines

At present, the utilization rate of pure water direct drinking machines is relatively high. Many families have purchased equipment such as direct drinking machines. In some public places, the use of large direct drinking machines also provides people with better water sources. Pollutants, such as rust, colloidal substances, peculiar smell and smell, residual chlorine and some disinfection by-products, organic pollutants, heavy metals, etc. can be removed. The purified water can be directly consumed.
The pure water straight drinking machine does not contain minerals and is not recommended for long-term use.
Purified water straight drinkers clean and hygienic
The straight drinking water purifier is composed of ultrafiltration membrane and activated carbon. The ultrafiltration mode is a porous membrane with super "sieving" separation function. The pore size of 0.01 micron can filter out the small impurities in the water and let the water More hygienic and fresh. Compared with the bottled water, the direct water purification machine is directly purified and can be drunk at any time without storage, so it is cleaner and tastes very delicious. Compared with the higher cost of bottled water, after the initial investment of the direct drinking machine, it basically does not cost anything in the later stage. At the same time, it can also be used in humidifiers, beauty salons and other places, and the beauty effect is also good. It can also be used with an ice maker, you can see that the ice cubes produced have no peculiar smell and taste good.
Pure water direct drinking machine, the current type is mainly based on the above two, if it is used in public places, it is quite good to choose pure water direct drinking machine. But if it is used at home, especially for a long time, the water purifier straight drinking machine is still good. The minerals in the water can be retained, which is more helpful to human health. Choose to use the straight drinking machine, which is cleaner, safer, and healthier than ordinary drinking water and bottled water. It is completely optional.

Comparative analysis of solar and gas water heaters

Water heaters are indispensable in people's lives. The most widely used water heaters on the market are solar water heaters and gas water heaters. The two types of water heaters have their own shortcomings, and the user has to make it according to his own needs when choosing. There are differences in water output, energy consumption, safety, and comfort. Therefore, it is recommended that users understand these two water heaters when choosing these two water heaters. Let's follow the editor to understand the advantages and disadvantages of solar and gas water heaters, and conduct a comparative analysis of solar and gas water heaters.

Solar and gas water heaters-from a safety perspective

Solar energy uses pure natural clean energy as the energy source for heating water, which is very safe to use. Users can rest assured that gas water heaters use natural gas. After the combustion is completed, a large amount of exhaust gas will be generated. In addition to a large amount of carbon dioxide, there is also a small amount of carbon monoxide in the exhaust gas. If there is no ventilation window, it may cause carbon monoxide poisoning. Use gas water heaters also need to be cautious, choosing high-quality gas water heaters can effectively avoid some safety hazards.

Solar and gas water heaters-from the perspective of comfort

The installation of solar energy is more complicated and will also affect the beauty of the building. It needs to be watered before use, and it may be delayed due to insufficient water. However, once the water is sufficient, the solar water heater is still relatively comfortable. The gas water heater is also very comfortable to use. If the user sets the water temperature, the gas water heater will operate according to the set temperature. It can also automatically enter water and dynamically adjust the water temperature. It is also very convenient to use.

Solar and gas water heaters-from the perspective of water storage

Gas water heaters can be divided into 5 liters, 7 liters, and 8 liters according to their models. Generally, gas water heaters can produce 5 liters, 7 liters or 8 liters of hot water at 50°C per minute. The solar water heater has a relatively large capacity and a faster heating speed. If you calculate that it takes about 50 kg of hot water per person to take a bath, you can wash 2.93 people per day.

Choosing the right water heater can provide the family with a comfortable home environment. From the above analysis, we can see that solar and gas water heaters have their advantages and disadvantages. Generally, the water heater used in residential buildings is gas water heater. If it is an exclusive single-family campus, solar energy is used. There are many users of water heaters, and it is recommended that users choose according to their usage.
