Everyone knows that the quality of the water purifier depends on the quality of the filter element. The filter element needs to be replaced and has a service life. Therefore, the water purifier must pay attention to the cleaning and timely replacement of the filter during use to ensure the health of drinking water. Therefore, the key to choosing a good water purifier is to choose a filter element with long service life, good filtering effect, convenient cleaning or replacement.
Coarse filtration / microfiltration
It is simple filtration, which uses the pores on the surface of the membrane for filtration. The pore size of the microfiltration membrane is generally 0.5-1 micron. It can only filter visible impurities such as mud, rust, colloid and large bacterial clusters. Membrane treated water can only be clear in the senses, and can not be used as drinking water. The market is more common is a tube, two tubes, three tubes of filtration.
Ultrafiltration
Referred to as UF, it is a physical screening process that uses pressure as a driving force to separate liquids by using different pore sizes of ultrafiltration membranes. The molecular cutting amount (CWCO) is generally 6,000 to 500,000, and the pore diameter is 0.1-0.01 micrometer. In water treatment, it can mainly filter macromolecular organic substances such as bacterial viruses, pigments, carbon powder, etc., but for pesticides, herbicides, detergents. Other substances such as low molecular organic substances and ions cannot be effectively removed. In general, the water purified by the ultrafiltration water purification product with an ultrafiltration pore size of 0.01 can reach the standard of direct drinking. If the pore size is 0.1 micron or more, the standard of direct drinking is not reached. Please pay attention when purchasing.
Nanofiltration
NF, a kind of reverse osmosis membrane, is a pressure-driven membrane nanofiltration membrane between reverse osmosis and ultrafiltration with a pore size ranging from 0.01 to 0.001. Under this pore size, pesticides, herbicides, Low-molecular organic matter and heavy metals such as detergents cannot pass, and ions smaller than this pore size can be partially passed. Because of the difference between ultrafiltration and reverse osmosis, such machines are not widely marketed.
Reverse osmosis membrane
Referred to as RO, using a special high-pressure water pump, the raw water is added to a pressure of 6-9 kg, so that the raw water permeates through the reverse osmosis membrane with a pore diameter of only 0.0001 μm under the action of pressure. Chemical ions and bacteria, fungi, and virions cannot pass, and with the discharge of wastewater, only water molecules and oxygen molecules having a volume of less than 0.0001 μm are allowed to pass. This principle achieves the purification of water without changing the properties of water and the amount of oxygen dissolved, and has been praised by experts as "Rolls Royce" in water treatment technology. The taste is better, it is the pure water we often say, but there are no other ingredients, including beneficial minerals, so it is not helpful.
