Retein

A drop in the ocean doesn’t make any difference. Not until you realize that this drop corresponds to the fraction of water on Earth that is safe to drink. Removal of newly discovered pollutants such as microplastics and pharmaceutical residues require new ways to purify water. Or perhaps not? Retein develops water filters that harness the finest water purification process available in Nature, which is uniquely able to produce extremely pure water at low energy cost. Retein thereby aims to accommodate the needs of a billion people and industries alike by turning any source water into pure water in a cheap and environmentally friendly way.
