Home water purifier water dispenser selection guide: principles, scenarios and FAQs

In modern family life, home water purifiers and water dispensers have become indispensable equipment for many families, and they provide us with a more convenient and healthy way of drinking water. However, in the face of the wide variety of products on the market, how to select the most suitable water purifier and water dispenser for your family? This requires us to have some knowledge about them.

The working principle of home water purifier
The core working principle of the water purifier is to filter and purify water through a variety of cartridges, mainly including physical filtration, chemical adsorption and biodegradation. Physical filtration is through the pore size of the cartridge to block the impurities in the water, such as sediment, rust, suspended solids, etc., like a sieve, the larger particles of impurities sieve out. Chemical adsorption is the use of activated carbon cartridge and other materials, chemical adsorption, to remove odor, residual chlorine and some organic matter in the water, activated carbon has a great surface area, can adsorb a variety of harmful substances in the water. Some advanced water purifiers may use biodegradation technology to remove organic pollutants from the water.
Common types of water purifiers are ultrafiltration water purifiers and RO water purifiers. Ultrafiltration water purifier core cartridge is ultrafiltration membrane, filtration accuracy of about 0.01 microns, can remove most of the bacteria, viruses and larger particles in the water. RO reverse osmosis water purifier adopts reverse osmosis membrane technology, filtration accuracy of up to 0.0001 microns, its working principle is under the action of high-pressure, only allows water molecules to pass through the reverse osmosis membrane, and will be in the water of the tiny particles, heavy metal ions, bacteria and viruses and other harmful substances are blocked in the water. Viruses and other harmful substances in the water are blocked outside the membrane, after its filtration of water can reach the drinking standard, is currently the best filtering effect on the market type of water purifier.

Applicable scenes of household water purifier
Different types of water purifiers are suitable for different scenarios. Ultra-filtration water purifier due to its relatively low filtration precision, can not effectively remove heavy metal ions and dissolved substances in the water, but it does not need electricity, relying on natural water pressure can work, simple structure, easy to install, suitable for families in areas with good water quality, as well as limited budget and water quality requirements of consumers are not high. RO reverse osmosis water purifier is suitable for poor water quality areas, such as some of the old city water network aging, the water may contain more heavy metals, bacteria and other harmful substances, RO reverse osmosis water purifier can effectively remove these impurities, to provide families with safer and healthier drinking water, but it is on the power supply and space has certain requirements, and the overall price is relatively high.

The working principle of household water dispenser
Household water dispensers are mainly divided into two kinds of barrel water dispensers and pipeline water dispensers. Bucket water dispenser is placed in the water dispenser on top of a bucket of water, through the top of the water dispenser body connector or suction pump will be sucked into the water dispenser inside, so that people can pick up drinking, this kind of water dispenser in the middle of the 20th century began to appear and is widely used, and today's suction pump bucket water dispenser is more safe and hygienic. Pipeline water dispenser is the first tap water purification, and then through a pipeline pure water access to the water dispenser inside, it has a connector and a water pipe connected to the supply of water sources, such as tap water, and is equipped with a water purification system to purify tap water, because of its ease of use, and gradually become the mainstream of the water dispenser market, widely used in offices and other places.
From the functional point of view, warm and hot water dispensers and hot and cold water dispensers work on different principles. Warm water dispenser in use, press the heating switch, the power supply is divided into two ways, all the way to form a heating circuit, the other way for the heating indicator to provide power, when the water temperature drops below a certain temperature, the water dispenser inside the thermostat contacts connected to the heating circuit, the electric heaters to continue to heat the water, so that the water temperature is maintained at about 95 degrees Celsius. Hot and cold water dispenser is in addition to the heating system, but also equipped with a cooling system, usually using refrigerant to achieve the cooling of the water, so as to be able to quickly provide hot or cold water according to user demand.

Frequently asked questions and answers about home water purifier water dispensers

1. What should I do if the water production of my water purifier drops drastically?
A: First of all, make sure the ultrafiltration membrane cartridge is in a wet state, drying out will cause the water production to drop and cannot be recovered. Secondly, you can try to flush and backwash the water purifier to remove any contaminants that may be clogging it.

2. Do I need to rinse the tap water when using the water purifier?
 A: It is recommended to turn on the tap to rinse the purified water after taking it, to flush out the trapped pollutants in time and keep the water throughput of the water purifier high.

3. How to use the water purifier when the tap water is out?
A: First, drain the sediment and rust from the tap water pipe, and then turn on the faucet to use the purified water.

4. Does the inlet water quality of the water purifier have any effect on the water production?
A: Yes, the water quality of the water purifier determines the total water production of the water purifier. Inlet water quality is better, the total water production will rise, and vice versa will fall, the filter life will be shortened accordingly.

5. What should I do if my water purifier malfunctions?
A: If the water purifier malfunctions, please immediately turn off the tap water valve, cut off the water intake of the water purifier, do not disassemble it by yourself, and contact the after-sales service in time.

6. What is the noise of the water dispenser during the heating process?
A: It means that the water dispenser has serious internal scaling and needs to be descaled.

7. water dispenser hot water pipe outlet white scale more how to do?
A: This is also a manifestation of internal scaling, you can use descaler to clean, or contact a professional for maintenance.

8. What do I need to pay attention to when I reuse the water purifier after a long period of suspension?
A: Before reusing the water purifier after a period of time, it should be rinsed repeatedly to eliminate the dead water in the water purifier.

9. How to solve the problem of cloudy water from water purifier?
A: If the inlet water pressure is too high or fluctuation is too large, caused by the ultrafiltration membrane rupture, need to replace the ultrafiltration cartridge; if the ultrafiltration membrane on the O-ring leakage, need to re-install or replace the O-ring; if the original water containing Fe2, Mn2 ions is high, you can increase the front of the removal of manganese and iron treatment.

10. How to do the water purifier produce water with odor?
A: If the residual chlorine odor in the water, the water purifier can be used normally; if the water purifier is a long-term suspension of the result, the need for repeated rinsing; if the water purifier for a long time without rinsing the retention of the formation of scaling within the cartridge, can be repeated rinsing or contact with the service center of the water purifier; if the water purifier within the protective fluid is not rinsed clean, you also need to repeat the rinsing or contact with the service center.
