Water purifier filter replacement of secondary pollution prevention - on a regular basis 【 3 m filter.

Recently, the Beijing media exposure nongfu spring & other; Bottled water is better than tap water & throughout; Bottled water, bottled water hygiene standards & other; Chaos & throughout; Caused the social concern. Bottle ( Barrels a day). Water companies should follow the national standard. Recent media and society on the bottle ( Barrels a day). Water standard issue of concern for a reason, the government departments should strengthen the regulation of this kind of drinking water. “ Regulation should be of the whole party, aiming at each link in the process of production, circulation. ”
bottled water problem more severe than bottled water, the bottled water, bottled water market is a bit messy. Compared with bottled water, bottled water is more serious health problem. If a bucket of water didn't drink in one day, the bacteria is likely to be overweight. Therefore, he suggests a bucket of water, such as not within 24 hours after drinking, the second day should be in a new barrel; In addition, regular cleaning tank of bottled water equipment, avoid bacterial breed.
compared with bottled water, the water purifier of health hazard. It can eliminate the secondary pollution of tap water pipe, it is understood that a water purifier company in Shanghai in the first quarter of this year's sales increased by 50% than the same period last year, shows that people pay more and more attention to the quality of drinking water. But the expert reminds, users in the process of using remember water purifier filter replacement, otherwise it will cause another form of & other; Secondary pollution & throughout; 。
water purification device has a variety of filtering technology. A technique called & other; RO reverse osmosis technology & throughout; , can will tap water filter into pure water, but scientific research has shown that pure water is not suitable for long-term drinking. Water should be beneficial to human body health is weak alkaline, activity strong, contain mineral water.
the second technology is & other; PP cotton + activated carbon & throughout; 。 PP cotton can filter the coarse particles, and unable to filter the bacteria in the water. Activated carbon to adsorption of bacteria and residual chlorine in tap water, the water taste better. The disadvantages of this technology is that must & yuml; Every two or three months to replace activated carbon, otherwise it adsorption of harmful components will cause & other; Secondary pollution & throughout; 。 The third technique is & other; Microfiltration & throughout; , microfiltration membrane aperture is 0. 1 - 0. 2 microns, due to the diameter of the bacteria in 0. 1 micron or so, the film cannot completely remove bacteria.
the fourth technology USES & other; Ultrafiltration membrane & throughout; The aperture is 0. 01 microns, is 1/10 the size of the bacteria, so bacteria can filter out all; At the same time. Because of its aperture is greater than the calcium ion, & thorn; Minerals, such as ion of ultrafiltration membrane can retain the minerals in the water. The Shanghai world expo park straight drinking water project, USES the is & other; Ultrafiltration membrane + activated carbon & throughout; Technology, with ultrafiltration membrane & other; Cooperative engagement & throughout; Later, the service life of activated carbon will be long, can have six months to change once a year.
