In addition to the “Standards for Drinking Water for Urban Residents” (the standard for tap water) issued by the Ministry of Health of China in 1985, there are stricter requirements on the number of bacteria and microorganisms. Therefore, the water purifier should be straight. Drinking standards must have antibacterial effect on the filter media. Ultrafiltration membranes (filtering accuracy 0.01 μm, currently known as the smallest virus 0.02 μm) and nanofiltration membranes (filtering precision 0.001 μm) are used in the water purifiers marketed. ), silver-loaded ceramic filter (such as the British Royal Dalton ceramic filter), equipped with ultraviolet germicidal lamp or ozone generator can inhibit bacteria, other equipped water purifiers can not meet the requirements of direct drinking.
Water purifiers and pure water machines have their own uses, depending on the water quality of the site. Regardless, the choice of Jinan pure water equipment depends on your local water quality.
The filtration of pure water machine adopts reverse osmosis technology. The water quality of pure water equipment company reaches the standard of pure water. In addition to the part that the water purifier can filter, the pure water machine can also filter heavy metal ions, especially carcinogenic nitrite. The requirements for the pure water machine are in line with the "General Water Filter - Reverse Osmosis Device", that is, the pure water standard.
What is a water purifier?
1. Classification of water purifier
There are also many types of water purifiers, which are divided into coarse filter and ultrafiltration water purifier according to the number of filter elements used. Generally use PP fiber cotton, coconut shell activated carbon, American KDF, ion exchange resin, tourmaline ore, medical stone, nano ultrafiltration membrane and other water treatment materials, there are first to nine filter cartridge water purifier.
2, the function and shortcomings of the water purifier:
According to different filter elements, the coarse filter water purifier can filter out impurities, rust, some bacteria, viruses, colloids, etc. in tap water, but the effect on heavy metals and water alkali is not great, and the ultrafiltration water purifier of level 5 or above is increased. The US KDF filter element and ion exchange resin filter element effectively remove heavy metals and water alkali, and the activation and mineralization filter elements are added at the 7th level or above. Therefore, the water purifier can not only achieve the purpose of direct drinking by the user, but also the purpose of health care.
3. Advantages of Jinan pure water equipment:
Safe to drink, retain most of the minerals in the raw water, soften the water, no waste water, no electricity.
4, the characteristics of the water purifier:
There is no motor, no power supply, and the water pressure drives the filter. There is no water storage tank, it is better to filter nine levels.
What is a pure water machine?
1, the working principle of pure water machine:
The technical core of the pure water machine is the reverse osmosis membrane. Its working principle is to exert a certain pressure on the water, so that the water molecules and the ionic substances pass through a reverse osmosis membrane, and most of the organic matter and bacteria dissolved in the water, The virus and the like cannot pass through the reverse osmosis membrane, and the reverse osmosis pure water equipment strictly separates the pure water and the impervious concentrated water. The pore diameter on the reverse osmosis membrane is only 0.0001--0.001 micrometer, which is equivalent to a hair strand. One millionth. The smallest size virus is also above 0.2 microns, so they are not transparent to the reverse osmosis membrane.
2, the category of pure water machine:
According to the use situation, it can be divided into manual type (also economical type) and automatic type. The difference is only in the backwashing aspect of pure water machine. The economical pure water machine uses manual backwashing valve.
4, the characteristics of pure water machine:
There are booster pumps, power supplies, water storage tanks, generally five-stage filtration, the first stage is the filter element, the second and third stages are activated carbon, and the fourth stage is the RO reverse osmosis membrane for aerospace technology (this is Core), the fifth grade is refined activated carbon, which is mainly used to improve the taste. It can also be placed in the fifth stage of the medical stone filter to become a mineral drinking pure water machine.
5, the function of pure water machine:
It can not only remove impurities, rust, sediment, colloids, bacteria, viruses, but also remove radioactive particles, organic matter, fluorescent substances and pesticides harmful to the human body. It can be said that there is substance other than water molecules. Very clean water.
