“The Netherlands lives with water. Developments such as population growth, urbanisation and the rising sea level are making it an ever greater challenge to make sure that water is managed sustainably. Ingenuity is needed to ensure that the right quality water is available constantly, and in the right quantities” (SenterNovem, 2016). One recent innovation to make sewage treatment more efficient is Nereda. Nereda® is an innovative, advanced biological wastewater treatment technology that purifies water using the unique features of aerobic granular biomass.
