This is a simple filter, the sediment filter cartridge is generally made of PP cotton and quartz sand, particulate matter or compressed activated carbon filter element, or KDF particulate matter. The pore size of the microfiltration membrane is generally 0.5-1 μm, and there are only visible residues such as fine sand, rust, and colloidal solution and their large bacteria. The water treated by the microfiltration membrane can only be perceived as clear and cannot be consumed as standard drinking water. It is a simple filter device commonly found in the market.
UF for short, also known as hollow fiber, is a physical sieving process that uses the pore size of ultrafiltration membrane to separate liquids; the pore size is generally 0.1-0.01 μm, and it is mainly used to filter biological macromolecular organic compounds such as bacteria, virus infections, and toner in sewage treatment. However, it cannot reasonably remove organic compounds with low molecular structure such as fertilizers, herbicides, and detergents. Heavy metals exceed the standard, and harmful chemical substances such as iron and manganese ions formed during the transportation of drinking water cannot be reasonably removed; generally speaking, the water purified by uf membrane module can be drunk immediately.
Ultrafiltration filtration is carried out by means of membrane filtration driven by pressure difference. Most uf membrane module are made of acetate fibers or fiber materials with similar properties. It is most suitable to solve the separation and concentration of substance concentration in saturated solution. It is also commonly used in the separation of colloidal mixtures that are difficult to complete by other separation techniques. Its main use is constantly developing.
Nanofiltration is abbreviated as NF. The pore size of the nanofiltration membrane is between 0.01-0.001μm, which can filter organic chemical pollutants such as antibiotics, growth hormones, fertilizers, crude oil, detergents, heavy metals exceeding the standard, and algae toxins; minerals below this pore size Positive ions can pass; favorable minerals can be reasonably preserved.
4. RO reverse osmosis
RO reverse osmosis is abbreviated as ro, that is, a specially made high-pressure pump is used to increase the working pressure of the source water, so that the source water can penetrate into the reverse osmosis membrane cartridge with a pore size of only 0.001 μm under the action of the working pressure. Organic chemical positive ions, bacteria and virions cannot pass through, and are discharged with wastewater. Only pure water molecules with a volume of less than 0.0001 microns are allowed to pass through, that is, pure water. There are no minerals that are good for the body, and long-term drinking is not good for the body.
