Ozone is used to disinfect water and it also absorbs ultraviolet rays. Other uses of ozone are as follows:
1. Kills bacteria effectively.
2. Oxidises substances such as iron and sulphur so that they can be filtered out of the solution.
3. There are no nasty odours or residues produced from the treatment.
4. Ozone converts back into oxygen quickly and leaves no trace once it has been used.
