What is the difference between activated carbon technology and ultrafiltration membrane technology?
Activated carbon technology and ultrafiltration membrane technology are essentially physical filtration, so it will become a hotbed of microorganisms, and the health system experts will spend 10 days or so when using a water purifier without a bacteriostatic (sterilization) device. The index will be greatly increased. Regardless of whether the ultrafiltration membrane is used for positive or recoil cleaning, the effect is not satisfactory. Besides, 7 days, the consumer is not annoying?
The nitrite concentration is high. Activated carbon and ultrafiltration membrane technology are the best solutions for dealing with organic pollution and residual chlorine. However, everything has two sides. In areas with serious organic pollution and obvious turbidity, this technology will lead to an increase in microbial indicators, resulting in nitrite concentration. Increase, its most direct performance is that the water purifier takes a period of time, the water quality will become salty! Not only affects the taste, but also seriously threatens human health.
Despite the slow development of the water purifier industry, despite the many problems with water purifier products, it is the sun that will eventually rise from the east, and the water purifier will be the next 100 billion industry. Let us wait and see!
The principle of the water purifier is to finely filter the water.
The principle of the water purifier is to finely filter the water, remove the impurities bacteria and heavy metal substances in the water, but also retain the minerals. It should be said that the tap water is cleaner, the rust in the water pipe can be removed, and the sediment can be removed. The water molecule belongs to small molecule water and is relatively easy to be absorbed. This is also one of the advantages.
Now the city's water pipe network is relatively old, and there will inevitably be some impurities. The price of the water purifier is about 1,000 yuan, which can generally be tolerated. It is just that people do not think that he is important in the concept. Now the industrial pollution is getting worse and worse, the water purifier is very It will become a necessity in life.
It is mainly used to filter out chlorine, toxins, floating substances (such as carcinogenic asbestos, hormones that cause fat) and other harmful substances in the tap water. It is a necessary guarantee for healthy drinking water.
1. It can effectively remove sediment, rust and bacteria (E. coli, cholera, Shigella dysenteria, etc.) in water, and can charge heavy metal ions (lead, mercury, zinc, manganese, etc.) harmful to human body. ) Converted into a neutral mineral suitable for absorption by the body.
2. It can completely remove chlorine from water and inhibit the growth of fungal algae in water.
3. Remove organic chemicals (such as pesticides, bleach, chlorine and trihalomethanes) from water and remove the odor, so that the final water can reach the standard of raw drinks, and retain the useful minerals in the tap water. .
The filter element is the core equipment of the water purifier
The filter element is the core equipment of the water purifier, which is equivalent to people's heart. The quality of the filter material of the water purifier determines the effect of the water purification treatment. Only the price of the granular activated carbon material differs by several tens of times, not to mention the difference between the granular carbon and the carbon fiber material. Which factory does not want its products to be cheap, but between quality and price, we want to seek long-term development, and water quality is the first.
Different water purifier filters
There are three types of water purification equipment on the market, such as water softeners, water purifiers and straight drinking machines. Different water purifying equipments are composed of different filter elements. The core of the water softener is a resin filter, which can remove the hardness of water or alkaline ions, and is mainly used for the production of bathing and washing water. The resin filter element needs to be regenerated after a period of time, and it can be simply immersed in salt water. The special soft water machine has a salt pool and can be regenerated automatically or manually by using special salt, but it must generate certain waste water and use electricity at the same time. The water purifier is generally composed of PP cotton and activated carbon filter. The straight drink machine generally uses hollow fiber, OR film and KDF alloy filter on the basis of the water purifier to achieve better treatment effect. When consumers buy water purification equipment, don't look at what name it is, depending on what filter it uses.
The water purifier is not qualified, it is mostly the filter problem.
Some time ago, a notice published on the official website of the Ministry of Health showed that some imported small water purifiers were randomly selected and found that 8 companies including 3M, Mitsubishi and Matsushita and 11 models were unqualified. The main reasons for the unqualified quality of these purified water products include excessive arsenic, excessive total number of colonies, and unqualified organic removal rate. Some water purifier manufacturers claim that this problem is caused by the performance degradation of some product filters and filters. From this point of view, the filter element of the water purifier is the core issue.
Keep the clean water flow regularly and replace the filter
Many users of water purifiers will encounter such problems. The water purifier has been used for a while and the water purification is getting less and less. Since the adsorbent material such as activated carbon used in the water purifier filter has a certain capacity, when the harmful substances such as dissolved organic matter are saturated, it is no longer effective. It is normal for the water purifier filter to clog. When the filter element is blocked, the filter element should be replaced. Household replacement filters vary in frequency depending on the amount of water used, the quality of the raw water, and the model selected. Generally, households with good water quality need to replace or clean the filter element in about 3 months.
Therefore, Qingmei reminds: buy water purifiers in strict accordance with the recommended time on the instructions or half a year, regularly replace the filter, otherwise it will cause secondary pollution, not only can not purify but harmful to the body. Do not allow the water purifier to age or prematurely, and maintain or replace it regularly.
