Abstract:

Laboratory experiments have been run with the combination of ultrafiltration (UF) and sorption techniques/reverse osmosis (RO). The ultrafiltration of three different total bleachery effluentsshowed a COD removal od 55-60% and AOX removal of 65-75%. The decrease in toxicity was about 50% and the removal of substances with a bioaccumulation potential was arround 90%. It is not meaningful to make a cost estimation before these combinations have been studied for longer periods, on larger scales and with a with range of effluents. The problem of the final destruction of the polluants which have been removed remains to be solved.

Keywords:
