ABSTRACT
Studies concerning the removal of oil from model wastewater using the hybrid process combining
ultrafiltration and nanofiltration were performed. The separation and transport characteristics of the employed
membranes were determined. The content of oil in wastewater was estimated by the determination
of total organic carbon and oil concentration measurements using a Horiba OCMA-310. The investigations
of oil wastewater treatment were carried out in two stages. The permeate obtained from the UF process (the
first stage) generally contains less than 6 mg/dm3 of oil, whereas in the NF process (the second stage) the
complete removal of oil was achieved.
