Beschreibung
Zusammenfassung:	A process for the production of highly purified water 32 from Fischer-Tropsch reaction water 12 which process includes at least the steps of a primary treatment stage comprising biological treatment 14 for removing at least a fraction of dissolved organic carbon from the Fischer-Tropsch reaction water 12 to produce a primary water-enriched stream 16 a secondary treatment stage comprising solid-liquid separation 24 for removing at least some solids from at least a portion of the primary water-enriched stream 16 to produce a secondary water-enriched stream 28 and a tertiary treatment stage comprising a dissolved salt and organic removal step 30 for removing at least some dissolved salts and organic constituents from at least a portion of the secondary water-enriched stream 28.
