The "Consumer Guide for Household Direct Drinking Water Purifiers" published by the authoritative journal of China's home appliance industry "Electrical Appliances" magazine pointed out that the direct drinking water purifier equipped with RO reverse osmosis function is the most ideal water purification product at present, and the purified room temperature water can be directly drunk, so it is called direct drinking water.
The 2014 Lanzhou water pollution incident shocked the country, and after the incident, people's awareness of the safety of drinking water rose to a higher level. It is always uneasy about others, and drinking water health still has to be in their own hands to be safer. As a result, household water purifiers and direct drinking water machines have gradually been put on the agenda as standard for household appliances. More and more people have installed a variety of drinking fountains, direct drinking water machines, energy-saving water boilers and so on at home. Household water purifiers have also become one of the effective ways for end users to solve water pollution, and heavy metals that can cause cancer in water are the most concerned.
So, what kind of direct drinking water machine and water purifier can effectively remove heavy metals? At present, from the product technical point of view, suitable for household direct drinking water machine, water purification device, energy-saving water boiler, pure water machine, etc., can remove heavy metals have the following technologies: First, activated carbon adsorption Second, KDF (copper-zinc alloy) electrochemical reaction Third, RO reverse osmosis membrane filtration Simple ultrafiltration membrane is unable to filter out heavy metals, which is determined by the filtration pore size of its membrane, because the filtration pore size of the ultrafiltration membrane is generally 0.1 ~ 0.01um (micron), and heavy metals such as lead Pb2+ The diameter of the ion is 0.28 nm (nanometer), which is fully capable of passing through the pore size of the ultrafiltration membrane, and the filtration pore size of the RO reverse osmosis membrane is 0.0001 microns, that is, 0.1 nanometers, so it can filter out heavy metal ions. KDF (copper-zinc alloy) electrochemical reaction can remove heavy metals, the specific principle can be searched on the Internet, here is not much elaborated, but Xiaobi to remind everyone that this treatment of water electrochemical reaction will lead to the treatment of water copper zinc ions exceed the standard, in Japan, Europe and the United States and other countries have been banned from the drinking water treatment field.
The adsorption of activated carbon can remove some heavy metals in the water, and the removal rate of heavy metals has a great relationship with the quality of activated carbon. Activated carbon has coal charcoal, fruit shell activated carbon, bamboo charcoal, etc., the best is coconut shell activated carbon, different types of activated carbon prices are also very different, non-professionals are difficult to effectively identify, so to buy a direct drinking water machine, water purifier, energy-saving water boiler, it is best to choose a large brand or a company specializing in the production of drinking water purification equipment.
Installing water purifier equipment does not necessarily mean the purchase of a single direct drinking water machine equipment, but can also be purchased with on-demand configuration, just like we configure and assemble computers, as long as we can meet our drinking water needs. Of course, this configuration has to be considered according to the user's specific drinking water needs and budget. For example, personnel composition, housing water pipe distribution, household income, etc., this problem users do not have to investigate deeply, those direct drinking water machine water purifier drinking water solution providers will do a complete set of programs for you, professional things to professional people to do.
The filtration principle of the direct water purifier is actually the principle of physical screening, the smaller the pore size, the higher the filtration accuracy, and the safer the filtered water quality. Therefore, only if the filtration accuracy is less than the above heavy metal ions and virus diameter, it is possible to ensure that there is no heavy metal pollution and virus hazard in the water.
The "Consumer Guide for Household Direct Drinking Water Purifiers" published by the authoritative journal of China's home appliance industry "Electrical Appliances" magazine pointed out that the direct drinking water purifier equipped with RO reverse osmosis function is the most ideal water purification product at present, and the purified room temperature water can be directly drunk, so it is called direct drinking water. This purification effect is at least equal to the regular brand bottled water sold on the market, such as Yibao, Wahaha and so on.
In the process of producing direct drinking water, you need a good set of water purification equipment. In the field of direct drinking water, Xiaobian gives you a [Bilai] Zhuojian family business dual-use direct drinking machine!
