Water is crucial to everyone -- and thing -- on the planet. Yet according to the World Health Organisation (WHO), 1.6 million people die every single year from diarrhoeal diseases through a lack of access to clean water and basic sanitation.
The WHO goes on to state that 90 percent of those who die are children under five, the majority living in developing countries.
In light of such a serious problem, tools to purify water are hugely important. Technologies such as chemical treatment can be used to purify water and make it safe.
