Abstract

In the present study different type of analytic methods were applied for the description of the performance of ozonation/membrane filtration combined water purification method in case of oil contaminated water. The investigated micro- and ultra- (PVDF) membranes were not enough effective to the purification of oil contaminated waters. However a short ozonation pre-treatment increased effectively the elimination efficiency in the aspect of extractable oil content. Results highlighted that the decreased values of extractable oil content and chemical oxygen demand do not necessarily mean the reduced quantity of organic contaminants. Moreover, ozonation pre-treatment increased the total organic carbon content of the permeate. The present study highlighted that differences of applied analytic methods can results different conclusions in case of purification of oil contaminated waters.
