Table olive processing wastewater (TOPW)was degraded by indigenous microorganisms.
Suspended and attached growth reactors were examined forTOPW biodegradation.
Removal rates of 96.5% dissolved COD and 64.5% phenolic compounds were recorded in the biofilters.
Decolorization could not be achieved even under the most favorable conditions.
Electrochemical oxidation-BDDdecolorized/mineralized the biologically treated TOPW.
