Removal of micropollutants from water and installation for use therein

The invention pertains to a process for the removal of micropollutants and/or other pollutants from water, comprising subjecting the water to a consecutive combination of biological adsorbent filtration (BAF) followed by oxidation treatment (OT), preferably ozone treatment. In a preferred embodiment, an adjustable amount of the OT effluent, preferably an adjustable amount ranging between 10- 100%, more preferably 20 - 90%, more preferably 20 - 80%, most preferably 20 - 50% of the OT effluent, is recirculated to the BAF. The process may involve monitoring the formation of oxidation products at the end of the OT, and/or for measuring TOC, DOC, SUVA, ammonium and/or specifically targeted pollutants in or at the end of the BAF, and controlling the amount of BAF-OT treated water which is recirculated to the consecutive steps of BAF and OT based on the output of the monitoring step.
