Abstrakt
Effluents from the ships containing the petroleum compounds are very dangerous for the
marine environment, hence, they are pre-treated on ships and their concentrates are transferred in
harbours for further purification. Oily wastewaters are very difficult for treatment; therefore this
process is carried out in specialized wastewater treatment plants. The treatment of oily wastewaters
is made a more difficult by the fact that the wastewaters supplied are very different in composition.
In this work was carried out the evaluation of variability of the composition of wastewaters
collected from oily wastewater treatment plant, which was transferred from a harbour. Several
parameters characterizing the actual wastewater (oil content, oil droplet size distribution, pH, salt
concentration, surface tension, COD/TOC) were measured. The samples for analysis were collected
over a period of 2 months.
