A water purifier is a common household device. Its main working principle is to filter out various impurities in the water, including bacteria, viruses, heavy metals, etc., through a series of physical or chemical treatments to provide clean and safe water. drinking water.
Different types of water purifiers use different technologies and processing methods. Common working principles of water purifiers include the following:
1. Filter filtration: The filter in the water purifier can effectively remove large particles of impurities such as suspended solids, sediment, and rust in the water to ensure clear water quality.
2. Activated carbon adsorption: Activated carbon has a large specific surface area and can absorb organic matter, odor and residual chlorine in the water, improving the water quality and taste.
3. Reverse osmosis: Reverse osmosis technology is an efficient membrane separation technology with a filtration accuracy of 0.0001 micron. It can remove a variety of dissolved substances, heavy metals, viruses, bacteria and other harmful substances in the water, and obtain high-purity, low-content water. The quality of the effluent water is safe and reliable, but electricity is required during the water production process, and wastewater is generated, so it is suitable for use in all areas.
4. Ultrafiltration: Ultrafiltration is a pressurized membrane separation technology. It is a physical screening process powered by pressure difference. The separation molecular weight ranges from hundreds to millions, and the membrane pore size is about 0.001~0.2 microns. The filtration precision is 0.01 micron, it can filter macromolecular organic matter such as bacteria, viruses, pigments, and carbon powder, but it can filter low-molecular organic matter such as pesticides, herbicides, detergents, heavy metals, and harmful substances such as iron and manganese ions produced during the transportation of tap water. It cannot be effectively removed and cannot be drunk directly. It is suitable for families with good water quality.
5. Ultraviolet sterilization technology: Ultraviolet sterilization technology can kill bacteria, viruses and other harmful substances in water. It is a safe and reliable water treatment technology. This configuration is mostly found in high-end water purifiers.
6. Electrolysis descaling: Some water purifiers use the principle of electrolysis to decompose soluble salts in the water into ions, effectively removing scale and protecting household equipment.
Summary: The working principle of a water purifier is to combine these treatment methods and select appropriate technology and filter media according to different water quality and user needs, so as to achieve the purpose of purifying water quality. It is necessary to choose the appropriate water purifier type and brand according to the actual situation to ensure safe and reliable drinking water supply.
