Is the water purifier energized or not? What are their advantages and disadvantages?

The water purifier is electrified, and most of the current water purifiers are electrified.

Generally, the water purifiers that are not electrified are mostly ultrafiltration water purifiers, and the electrified water purifiers are mostly RO reverse osmosis water purifiers; Ultrafiltration water purifier adopts ultrafiltration membrane, and reverse osmosis water purifier adopts RO membrane, which has stronger water purification ability, better taste and wider application.

Rechargeable reverse osmosis water purifier has many models and a wide range of choices. The display screen can intelligently display water production, water fullness, maintenance and other States, which is more convenient to use. Recharged water purifiers do not consume electricity, and the failure rate will be lower.

In addition, the uncharged ultrafiltration (UF) water purifier can filter out harmful substances such as rust, sediment, suspended matter, colloid, bacteria, macromolecular organic matter, and retain some mineral elements beneficial to human body. The filter element can realize automatic flushing and backwashing, and the filter element is generally replaced once every three years.

Water purification standard

China's national industry standard for water purifiers was promulgated on 20 13, and the drafting meeting of four national industry standards for water purifiers/water purifiers was held on 2065438+. Among these four standards, the first two are national standards for water purifiers and mandatory safety standards. The latter two are industry standards and recommended product standards.

Development history of water purifier

/kloc-At the beginning of the 9th century, a very serious water pollution incident (one of the three major water pollution incidents in the world) occurred in the Rhine.

1826, the water pollution of the Rhine River spread to a small mountain village in Bonn, Germany, and the river has affected the normal life of the local people. In order to drink clean water, Paul Eric, who was only 13 years old, decided to make a water purifier with superhuman wisdom. After hundreds of failures, he finally succeeded in inventing the world's first water purifier:

The water purifier adopts a 20-layer thick rotary cloth bag filled with quartz sand and activated carbon, and the activated carbon is in the middle of the quartz sand. Then put the bag of water purification material on the top of the barrel, pour the polluted water on the gauze, let the water slowly flow into the barrel through multi-layer infiltration, and finally the filtered water is sweet and sweet. After many improvements, the filtration effect of the water purifier is getting better and better, which has attracted the attention of the local government.

With the general improvement of people's awareness of water purification, the water purifier industry has gradually emerged, and the development of domestic clean drinking water industry began in the 1980s.

Water is the source of life and the quality of drinking water is closely related to people's health. According to the survey of the World Health Organization (WHO), 80% of diseases and 50% of child deaths in the world are related to the poor quality of drinking water. A quarter of the population in China is drinking water that does not meet the hygienic standards, and "water pollution" has become the most important water environment problem in China.

After years of publicity and popularization of drinking water and health knowledge, people's water purifiers gradually understand the impact of drinking water quality on human health and pay more attention to drinking water safety, which provides a great market prospect for the production of water purifiers.

Household water purifiers have been used by 95% households in developed countries in Europe and America, while the domestic household utilization rate is less than 5%, so there is still a broad development space for water purifiers in China.

Since 2000, water purifier manufacturers have developed rapidly, and the water purifier industry has recovered and grown rapidly. The water purifier industry in China has grown to more than 3,000 manufacturers, and the number is still increasing at the rate of 30%-40% every year.

20 14 was affected by the odor of tap water in many cities, benzene pollution in Lanzhou tap water, ammonia nitrogen pollution in Hanjiang River and water pollution in Jingjiang, and the sales of water purifiers continued to heat up, and the water purifier industry in China developed rapidly.
