Bottled water is a cleaner way to consume water over traditional tap water. Bottled
water is filtered to remove any impurities or contaminants that may be present in the water. The filtration systems used in bottled water vary in their size and output, but all carry out more or less the same function of removing impurities.
The filtration systems used in bottled water uses a process known as membrane filtration that helps remove impurities such as organic pollutants, iron and other forms of ions. Ozonisation is another process used in bottled water filtration systems. This process breaks down organic materials in order to reduce their odour potential, sanitise the water and minimise the risk of bacterial contamination.
The two biggest selling forms of bottled water are still and sparkling water, each using their own system of filtration. Still water can either be purified through a filtration process, or its source could be an actual fresh-water spring. However, spring water still needs to undergo a filtration process whereby the water is treated with ozone to remove any impurities and to preserve the water in the bottle.
