How does the No Noise Uf Purifler use ultrafiltration technology to improve water quality?

The core technology used by the No Noise Uf Purifler is ultrafiltration, which is a membrane separation technology based on the principle of physical screening. Ultrafiltration technology can separate different components in water without applying chemical changes by using semi-permeable ultrafiltration membranes.
The pore size of ultrafiltration membranes is usually between 0.01 microns (10 nanometers) and 0.1 microns (100 nanometers). This pore size enables the ultrafiltration membrane to intercept most bacteria (usually larger than 0.2 microns), viruses (some viruses may be smaller than 0.1 microns, but ultrafiltration membranes are effective for large-sized viruses), parasites and their eggs, colloidal substances, and most suspended particles. The ultrafiltration membrane is made of polymer materials (such as polysulfone, polyacrylonitrile, polyvinyl chloride, etc.) and has a porous structure. These pores allow solvents (such as water) and small molecular solutes (such as inorganic salts, small molecular minerals, etc.) to pass through, while larger solutes (such as proteins, bacteria, viruses, etc.) are blocked outside the membrane.
The ultrafiltration process is usually driven by a certain pressure difference. Under the action of external pressure, the water source (such as tap water) passes through the surface and internal pores of the ultrafiltration membrane. When water passes through the ultrafiltration membrane, molecules and ions smaller than the membrane pore size (such as water molecules, soluble salts and small molecular minerals) can pass through the membrane pores smoothly and become permeate (i.e. purified water). Particles, colloids, bacteria, viruses, etc. larger than the membrane pore size are retained by the membrane surface to form a concentrated liquid (or retained liquid). In addition to the screening effect, adsorption and bridging phenomena may also occur on the surface of the ultrafiltration membrane. These phenomena help to further remove impurities in the water, but may also cause membrane pollution and blockage.
No Noise Uf Puriflers have no mechanical moving parts (such as pumps, agitators, etc.) during operation, so no noise is generated. The ultrafiltration process mainly relies on static pressure (i.e. the pressure of the water source itself or the slight pressure applied externally) to drive water through the membrane, thereby avoiding the noise and vibration caused by mechanical movement.
Ultrafiltration technology can effectively remove bacteria, viruses (partially), parasites, colloids, suspended particles and other impurities in water, improving the safety and cleanliness of water quality. Since the pore size of the ultrafiltration membrane is relatively large, it will not remove soluble salts and small molecule minerals in the water, so the purified water still retains these components that are beneficial to the human body.
