The drinking water system includes bottled purified water, bottled mineral water, bottled mountain spring water, barreled purified water, barreled mountain spring water (drinking packaged water), etc. Each process is slightly different, and the water used can come from spring water, well water, pure water, tap water and even municipal water supply. With the current aggravation of environmental pollution, the quality of raw water is not as good as before, and people’s awareness of health care has increased, the quality of bottled water has received more attention. Many countries, especially developed countries, have strict national standards to regulate the quality of bottled water. Bottled water has a large amount of particulate impurities, protozoan cysts/oocysts and microorganisms in its production process, so filtration is critical to its process control, not only to remove particulate impurities, microorganisms, can also be used for sterile filtration of carbonation and pressure backup gas to make water quality comply with relevant regulations and strive to improve the quality of produced water and reduce safety risks for consumers. Taking the production process of drinking purified water as an example, the main filtration sites of the whole process are as follows:
1. Pre-filtration: protect the water quality entering the ultraviolet, protect the ultraviolet disinfection equipment
2. Security filtration: pre-filtration before reverse osmosis to protect RO membrane
3. Sterilizing filtration: remove microorganisms such as bacteria and eggs in water to ensure long-term preservation quality of water
4. Respirator: for compress air or other protective gases, remove moisture, particles and bacteria
5. Stainless Steel filtration: intercept the residual/shedding particulate impurities in the pipeline

Common drinking purified water production process:
