Zusammenfassung:	The present invention provides an integrated zero liquid discharge process for treating palm oil mill effluent (POME), comprising of cooling of the POME to produce a pre-treated POME, flocculating and coagulating suspended solids contained in the pre-treated POME, dewatering or removing the flocculated and coagulated suspended solids, adding at least one electrolyte to the partially treated POME, delivering the partially treated POME to an electro-oxidation cell, removing precipitate and/or suspended solids from the partially treated POME and passing the treated POME through reverse-osmosis process and an ion exchange process to remove contaminants and dissolved ions from the treated POME to produce a zero liquid discharge, whereby the zero liquid discharge is colourless (
