A significant share of our product portfolio in our emerging markets and in the United States is made up of purified water or prepared water. More precisions about our categories of water.
The process aims to guarantee the highest safety standards for drinking water and ensure a taste that is in accordance with consumer preference.
- Water is carefully collected and received through stainless steel pipes from either a local well or municipal water supply. Quality testing of the original source is conducted regularly to monitor for abnormalities.
- This step is taken when the water originates from a municipal or public drinking water system. It consists of removing chlorines and THMs (trihalomethanes) through a daily-monitored activated carbon filtration process.
- A water softener is used to reduce water hardness.
- Demineralisation removes unwanted minerals (through reverse osmosis or distillation).
- Water received in storage tanks is monitored on a daily basis.
- Selected minerals are added to cater to consumer taste preferences.
- Pharmaceutical grade micro-filtration removes particles as small as 0.2 microns. It is also capable of removing potential microbiological contaminants. This is monitored on an hourly basis.
- Ultra-violet filtration provides additional product disinfection. This is monitored on an hourly basis.
- Ozone disinfection is the third disinfection step (steps 7-9), using a highly reactive form of oxygen. This is monitored on an hourly basis.
- The filling room is highly sanitary to ensure bottling is conducted in a microbiologically controlled environment. It is continuously monitored and controlled.
- Packaging quality assurance is conducted by human inspection and the latest in modern equipment designed to ensure the removal of any packaging defects.
- Line sanitation includes automated cleaning equipment to ensure maximum cleanliness, effectiveness and control.
