The reverse osmosis water purifier is a household drinking water equipment that has not appeared in the market for a long time, but its appearance has been well received by more and more consumers, especially by the users of household water purifiers, because he is a human door. The cost of purchasing bottled water and the cumbersomeness of transporting bottled water are eliminated. The biggest difference between a pure water machine and a water dispenser is that a pure water machine is a device for manufacturing pure water, and a water dispenser is a device that heats or cools pure water and is convenient for people to quote; currently, the three-temperature floor type household pure appear on the market. The water machine actually covers the function of the water dispenser.
one. Reverse osmosis pure water machine principle
The reverse osmosis pure water machine is a reverse osmosis membrane technology born in the 1950s. This technology is widely used in high-tech fields such as medicine (such as nephropathy for kidney disease), aerospace (astronaut fluid circulation), desalination, etc. In recent years, this technology has been used to develop water purification equipment for civilian use. Its working principle is to exert a certain pressure on the water, so that the water molecules and the ionic mineral elements pass through a reverse osmosis membrane, and most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in the water. Impervious to the reverse osmosis membrane, so that the shoulder-permeable pure water and the impervious concentrated water are strictly separated; the pore size on the reverse osmosis membrane is only 0.0001 um, and the diameter of the virus is generally 0.02-0.4 um, the diameter of common bacteria. There is 0.4-1um, so you can safely drink the clear spring flowing out of the pure water machine.
The normal operation of the reverse osmosis pure water machine depends on a certain pressure, which must be greater than the osmotic pressure of the permeable membrane, which is generally 2.8 kg/cm 2 . In areas where water pressure or water pressure is unstable, we recommend that you purchase a water purifier with a booster pump. It can work at pressures of 6-9 kg/cm2, is not subject to tap water pressure, and has high water production efficiency. The speed is fast, the concentrated water is less, and the daily water production is about 130 liters, which can fully meet the daily water needs of the family. At present, the daily domestic pure water machine on the market has a daily processing capacity of 50 gallons, and some products have a processing capacity of 75 gallons. Due to the larger processing capacity, it is suitable for more customers.
two. Household water purifier type
General household water purifiers have models and types that are suitable for different installation positions, so you must consider the installation factors when purchasing. If your living space is small, you should consider a table-type household water purifier. The under-counter household water purifier can be installed under the sink, and the water tap is fixed on the top of the pool. If there is a cabinet, it can be installed in the cabinet. It is characterized by not occupying a place and is convenient for cooking water. The desktop water purifier can be installed on the kitchen counter or in the living room near the water source. Its appearance is generally more elaborate and suitable for gift giving. The most complete function should be a three-temperature floor-type reverse osmosis pure water machine. It has a gorgeous appearance and can simultaneously produce three kinds of water at the same time. It is the perfect combination of pure water machine. The most stable one is the standard pure water machine. For example, the 5th standard pure water machine introduced by Hious in the United States is the best choice, and the daily processing capacity is 75 gallons. It is also possible to select a mineralized filter element or a filter element that adjusts the pH value according to the needs of the customer, giving the customer more choice of water supply. In addition, in general, products that have been certified by foreign strict brands can be purchased with confidence, such as certified products such as the American Water Quality Association.
three. Use of household water purifier
Pure water from household pure water mechanism is fresher, healthier and safer than bottled water. It is widely used: it can be used for raw drinks or boiled water. The most prominent feature in this respect is the kettle or electric heating bottle. It will not scale; convenient pure water is used for cooking, more hygienic and more delicious; bathing with pure water can remove impurities on the skin, moisturize the skin and provide natural beauty effect; can be supplied to humidifiers, steam Iron, beauty instrument and other small appliances need water, there will never be annoying white powder; with the ice machine, the ice cubes are crystal clear and without any odor.
