The modern life style of developed countries and the emerging needs for increased production of food involve extensive usage of artificial compounds, e.g. pharmaceutical compounds, personal care products, pesticides and other environmentally persistent chemicals. When those compounds are released in the aquatic environment mainly via sewage outlets, deteriorate water quality and expose both human and wildlife to risk. To address this issue, water disinfection appeared to be a necessity. The aim of Water ApS is to provide purification technologies which ensure safe water.
