First of all, we have to figure out why there is sediment in the tap water.

In fact, there is a large amount of sediment in the tap water, which is related to the secondary pollution of the tap water after being disinfected by the water plant in pipeline transportation. Many pipes begin to rust, decay, and even become full of red worms because of the material or age, and there are fewer devices at home to intercept these sediments, so these sediments directly enter the home pipeline. Even if the tap water is boiled, these deposits will still exist. The Water Purifier Spare Parts can not only filter out these sediments but also filter out heavy metals, viruses and bacteria in the water according to different water purification principles.

There are quite a lot of types of water purifier spare parts, mainly related to the filter element, and the degree of clean water obtained is different. However, there are two main types of household water purifiers commonly used in the market: ultrafiltration water purifiers, RO reverse osmosis. Water Purifier.

Many households come into contact with ultrafiltration water purifiers when they first come into contact with the water purifier. The core component of the ultrafiltration water purifier is the ultrafiltration membrane. The pore size of the ultrafiltration membrane is generally 0.5~0.01 micron. Combined with other PP cotton filter elements and activated carbon filter elements, it can effectively retain such as colloid, rust, suspended solids, sediment and large. Molecular organic matter, etc. However, the pore size of the ultrafiltration membrane is incapable of ionic substances in water, such as pesticide residues, heavy metals, organic matter, and the like. In other words, the water from the ultrafiltration water purifier contains suspected contaminants and does not meet the standard for direct drinking.

RO reverse osmosis water purifiers are generally referred to as pure water machines. RO reverse osmosis filtration technology was invented for the US space industry. It was first used by American astronauts to recover body fluids for pure water. The core component is an RO reverse osmosis membrane with an accuracy of 0.0001 μm, a bacteria usually has a diameter of 1 μm, and the virus is usually 0.02 μm in diameter, so it not only effectively removes harmful ions from water but also removes all bacteria and viruses. Only water molecules are allowed to pass. After RO filtration, the water is pure water and can be drunk.

Compared with ultrafiltration water purifiers, RO reverse osmosis water purifiers have obvious advantages, not only for areas with serious water pollution but also for meeting high standards of urban drinking water demand.
