Oxidative pre-treatment methods such as the Fenton oxidation, ozonation, and photocatalytic
treatment have been compared in reducing adsorbable organic halogens (AOX) and chlorophenolic
compounds in untreated kraft pulp bleaching effluent. Their efficiency was also studied on effluent
ultrafiltration fractions. The Fenton treatment removed all analyzed chlorophenolic compounds from
the effluent. Ozonation and photocatalysis appeared to be much less effective methods. The efficiency
of the Fenton oxidation appeared to be more pronounced in higher molecular weight effluent fractions.
This suggests a novel design, where the filtration stage can be placed after the oxidation, and the high-
-molecular weight fraction is returned to the Fenton treatment.
