PET bottled water that is widely sold in Thailand (Nestlé Pure Life, Singha Drinking Water, Crystal, etc.) is mainly manufactured using the following process.

  • RO treatment (reverse osmosis membrane filtration)
    Almost completely removes impurities and microorganisms. Because the mineral components are also removed, the taste is neutral (neutral pH 6.5 to 7.5) and less addictive.

  • UV sterilization or ozone sterilization
    Water is sterilized again after RO treatment to ensure safety.

Features

  • Suitable for mass production and inexpensive

  • Almost tasteless and odorless, easy to use for cooking and juices.

  • However, it contains almost no natural minerals.
