Clean water is a necessity, yet according to WHO, 844 million people do not have access to clean drinking water. The major culprit for water-related health problems are heavy metals, which may cause nausea, hyperpigmentation, sterility, cancer and even death. The second large problem is radioactive elements found in water.
In 2008, Goldmnn Sach’s estimated the water purification market to be €425 Billion with a long-term growth of 4-6% pa. However, there are no cost effective and efficient methods to extract heavy metal ions from drinking water today.
