Abstract: The invention relates to Method of removing dissolved organic carbons from raw water, containing suspended and/or colloidal matter in a suspended ion exchange process, comprising the steps of: -feeding the water into a plug flow reactor at a rate of at least 500m 3 /h preferably at least 1000m 3 /h, -adding an anion exchange material to the liquid at the inlet of the reactor, -suspending the anion exchange material in the water, -transporting the water and the suspended anion exchange material under plug flow conditions to an outlet of the reactor after a predetermined residence time, -feeding the water and the suspended anion exchange material to a separator and -feeding treated water and anion exchange material from a reactor outlet to a separator, wherein -the concentration of the anion exchange material in the reactor is smaller than than 20 ml/l, and -the residence time of the anion exchange material in the reactor is lower 30 minutes.
