Ultra-filtration membrane water purifier is a commonly used equipment, its function is still relatively powerful, its principle is mainly the use of cartridge filtration, the water sediment, bacteria, heavy metals and other substances removed, so as to get clean and healthy water quality. At present, the main source of pollution of household water is part of the factory wastewater discharge, thus polluting the local water source, forming chemical pollution. The ultrafiltration membrane of the water purifier can effectively remove such substances and separate out heavy metals, antibiotics and bacteria. It is very useful for any family to install a water purifier.
In the long-term use of the water purifier, in order to ensure the quality of water purification, we need to filter the water purifier, regular cleaning and replacement,? How long does it normally take to replace a water purifier cartridge?
Bacteria and colloids much larger than bacteria, rust, suspended solids, sediment, macromolecules and other organic matter can be retained by the ultrafiltration membrane, generally used in the third level of the water purifier. The filtration accuracy of 0.01μm. ultrafiltration membrane cartridge replacement cycle: generally in three years or more than three years.
The following phenomenon, it shows that the cartridge needs to be replaced:
Generally speaking, there is a replacement cycle of the cartridge, but the specific cartridge replacement time, still need to be based on the user's water quality and use of water purification and change, but encountered the following four cases of the cartridge should basically change.
1, the water flow is significantly smaller. Description of the cartridge clogging, should be cleaned in order to restore the normal flow, after cleaning the flow is still very small, it is necessary to replace the water purifier with a new cartridge; replacement of the method of investigation, from the primary PP cotton cartridge in turn to the back step by step, until the normal amount of water;
2, the water taste decline, taste and tap water close to the tap water can not be removed the taste of the residual chlorine of the tap water, indicating that activated carbon cartridges have been adsorption saturation, activated carbon cartridges should be replaced. Activated carbon filter should be replaced.
3, RO membrane reverse osmosis water purifier too fast. Water purifier water significantly faster phenomenon, this situation is generally due to RO membrane damage caused by this time we must replace the new RO membrane, otherwise reverse osmosis water purifier will lose the core heavy metal ion filtration function.
4, water purifier cartridge by time projected to 80% of the service life. The life of the cartridge is the ideal situation of the use of the period, for the serious water pollution in the community, the cartridge is simply no way to use such a long time, generally in the use of the cartridge time to reach its ideal life expectancy of about 80% of the time, it can be replaced.
