Abstract
The invention pertains to a method () of at least partly removing at least one micropollutant from wastewater () comprising carbogenous compounds and at least one micropollutant. The method comprising the steps of: (a) dividing the wastewater () into a main stream () and a side stream (); (b) treating main stream () with bacteria to reduce the content of carbogenous compounds to provide depleted wastewater () comprising at least one micropollutant; (c) treating the depleted wastewater () with a second portion of microorganisms (), having the ability of degrading the at least one micropollutant, to, at least partly, remove the at least one micropollutant thereby providing treated water (), wherein the second portion of microorganisms () have been enriched by feeding the side stream () to it before using the second portion of microorganisms () in treating the depleted wastewater (); and (d) feeding a first portion of microorganisms (), having the ability of degrading the at least one micropollutant, with the side stream (), to enrich them for subsequent use in treating the depleted wastewater () to at least partly remove the at least one micropollutant.
