Its preparation process generally includes several steps, such as reverse osmosis, ion exchange, electrodialysis, distillation, ultrafiltration and so on. Water with high purity, low ion content and low organic matter content can be prepared.
Pure water is widely used in laboratory, medicine, electronics, chemical industry and other fields, such as preparing solutions, medicines, electronic components, chemical reagents and so on. It has a certain pH value and conductivity, and is usually used to replace ordinary tap water or purified water for experiments and production.
It should be noted that although the impurity content of pure water is very low, it does not mean absolute purity. In practical application, further treatment and detection are needed according to specific needs and requirements to ensure the quality and safety of water.
The role of pure water
1. Removal of suspended solids and particulate matter: Pure water can remove suspended solids and particulate matter in water, such as sediment, sand and microorganisms. Through filtration, precipitation and adsorption.
2. Removal of dissolved substances and ions: Pure water can remove dissolved substances and ions in water, such as minerals, heavy metals and organic substances, through reverse osmosis, ion exchange and distillation.
3. Removal of microorganisms and pathogens: Pure water can remove microorganisms and pathogens in water, such as bacteria, viruses and parasites, through ultraviolet disinfection, ozone treatment and high temperature sterilization.
4. Improve the conductivity and purity of water: Pure water can reduce the conductivity of water and improve the purity of water to meet the requirements of different fields, such as laboratory analysis, electronic manufacturing and pharmaceutical production.
5. Maintain the stability and consistency of water: Purified water can maintain the stability and consistency of water to ensure the same quality of water in different batches and meet the requirements of production and scientific research.
