In everyday life, we often hear ""."Purified water" and "pure water".These two words, but what exactly is the difference between them?
First, the water quality standards are different
Clean waterIt refers to the removal of suspended solids, sediments, odors, chromaticity and other impurities in the water through physical or chemical methods to reach a certain water quality standard and can be used by people.
WhilePure waterIt refers to the removal of almost all impurities in the water, including minerals, microorganisms, heavy metals, etc., through more advanced purification technology, to achieve higher water quality standards.
Second, the purification principle and effect are different
Clean waterIt is to remove insoluble impurities and some soluble impurities in the water by filtration, adsorption, disinfection and other methods, and retain the nutrients such as minerals and trace elements in the water. However, water purification cannot completely remove all impurities in the water, such as some tiny viruses, bacteria, heavy metals, etc. Therefore, clean water is not a complete replacement for pure water.
WhilePure waterIt is to remove all impurities in the water, including minerals, microorganisms, heavy metals, etc., through reverse osmosis, distillation, electrodialysis and other methods, to achieve higher water quality standards, aiming to improve the purity of water to the highest degree.
Overall, the biggest differences between clean water and pure water are:
1. Water purification is to remove some harmful or unnecessary components on the basis of tap water, so that water is more suitable for human drinking and use, while pure water is to completely remove all components in the water, so that the water can reach the purest state.
2. The treatment method of water purification is generally physical or chemical methods, such as activated carbon, ultrafiltration, etc., while the treatment method of pure water is generally reverse osmosis or distillation and other methods, such as RO membrane, ion exchange, distiller, etc.
In summary, although purified water and pure water are both processes of water purification, there are differences in water quality standards, purification principles and purification effects.
