A water filter based on sand and nanomaterials that removes heavy metal ions, radioactive elements, organics, aromatics and microbes from contaminated water. This filter has been developed after 9 years of R&D. The filter is recyclable after use and respects the circular economy principles. On recycling the sand is reused and the metals obtained as a result of extraction can be sold on the market. Our filter even degrades organics and aromatics and has anti-microbial qualities. We provide a cost-effective solution to decontaminate water based on 99% natural materials viz., sand. The technology is cost-effective, within everyone's reach with a positive impact on the economy and the climate creating a huge socio-economic impact. Also we ensure the sustainability of a natural resource like water by providing a sustainable product. Other resource recovery includes recovery of metals thereby making mining more efficien
