water-purificationAccording to the World Health Organization, 748 million people lack access to uncontaminated drinking water sources. Moreover, WHO estimates that 1.8 billion people use a fecally contaminated drinking water source, 2.5 billion lack access to improved sanitation facilities and more than 840,000 people die from water related diseases annually. Contaminated water is the number one cause of death in developing countries, causing diseases such as cholera, hepatitis, typhoid fever, malaria, ascariasis, dengue fever and many other deadly illnesses.

In fact, contaminated water is the number one public health concern globally based on its impact to society, according to the WHO. Fortunately, the WHO estimates that 10% of the global disease burden could be prevented with improved water supply and sanitation. In light of this, a number of water purification designs and technologies are providing growing solutions to this problem.
