The water purifier is electrified, most of the water purifiers are electrified.
Generally do not electrify the water purifier is mostly ultra-filtration water purifier, electrified most of the RO reverse osmosis water purifier; ultra-filtration water purifier using ultra-filtration membrane, reverse osmosis water purifier using RO membrane, RO membrane water purification ability is better, purified pure water taste better, more widely used;
Electrified reverse osmosis water purifier, more models, a wider range of choices, with a display screen that can Intelligent display of water production, water full, maintenance and other states, more convenient to use; water purifier without electricity does not cost electricity, the failure rate will be lower.
In addition, without electricity ultrafiltration (UF) water purifier, filtering out rust, sediment, suspended solids, colloids, bacteria, macromolecules, organic matter and other harmful substances in the water, and can retain some of the mineral elements beneficial to the human body. The cartridge can realize automatic flushing and backwashing, and the cartridge is generally replaced once every three years.
Expanded
Water purification standards
China's national industry standard for water purifiers was promulgated in 2013, of which the "Household and similar electrical appliances for the safety of ultraviolet radiation water processor appliances with the special requirements", "Household and similar electrical appliances for the safety of the hot and cold water dispensers with the special requirements", "Household and similar electrical appliances for the safety of the hot and cold water dispensers with the special requirements", "Household and similar electrical appliances with the special requirements for the safety of the hot and cold water dispensers". Water purifier with ultraviolet sterilizer "," household and similar uses of reverse osmosis water purifier, nanofiltration water purifier with pressure tank " four water purifier national water purifier home / water purifier industry standards drafting work conference was held on May 17-19, 2013 in Kunming, Yunnan Province. Of these four standards, the first two are national standards for water purifiers, which are mandatory safety standards; the last two are industry standards, which are recommended product standards.
History of the development of water purifiers
In the early 19th century, the Rhine River, a very serious water pollution event (one of the world's three major water pollution events).
In 1826, the Rhine water pollution spread to a small mountain village in Bonn, Germany, the water has affected the normal life of the local people, only 13 years old Paul Eric in order to drink clean water, he decided to use superhuman wisdom to do a water purifier, after hundreds of failures, he finally succeeded in the invention of the world's first water purifier:
The water purifier is a 20-layer thick Fine gauze bag filled with quartz sand and activated carbon, activated carbon in the middle of the quartz sand, and then the bag of water purification materials on the top of the barrel, the polluted water poured on top of the gauze, so that the water slowly through the multi-layer infiltration flow into the barrel, and ultimately filtered water after the water is clear rut sweet, after a number of improvements in the water purifier filtering effect is getting better and better, causing the local government's attention.
With the general improvement of people's awareness of water purification, the water purifier industry gradually emerged, the domestic development of clean drinking water industry from the 1980s.
Water is the source of life, the quality of drinking water is closely related to people's health. According to the World Health Organization (WHO) survey shows that 80% of the world's diseases and 50% of child deaths are related to poor drinking water quality. A quarter of China's population is drinking water that does not meet hygiene standards, and "water pollution" has become China's main water environment problem.
After years of publicity and popularization of drinking water and health knowledge, people water purifier has gradually understand the impact of drinking water quality on human health, pay more attention to drinking water safety, which provides a great market prospect for the production of water purifier products.
Domestic water purifier in Europe and the United States in developed countries 95% of the families have been in use, while the domestic household usage rate of less than 5%, so the water purifier in the country there is still a vast space for development.
Since 2000, water purifier manufacturers have been rapidly developing and expanding, and the water purifier industry has been recovering and growing rapidly. China's water purifier industry has grown to more than 3,000 producers, and its number is still growing at a rate of 30%-40% per year.
In 2014, affected by the odor of tap water in many cities, benzene pollution of tap water in Lanzhou, ammonia and nitrogen pollution of the Han River, Jingjiang River water pollution and other events, the sales of water purifiers heat continues to heat up, the rapid development of China's water purifier industry, with a momentum of breaking the bamboo.
