Subject of this work was carrying out researches on removal of petroleum derivates in laboratory stripping tower. In researches model water was used, which was mixture of distilled water and petrol and diesel fuel mix in ratio of 1 to 3, next it was submitted to aeration. Repelling of petroleum derivatives was med in 4 series, starting researches from minimal concentration 0,132 µg/dm3 to 3,992 µg/dm3. Level of each concentration resulted from concentrations found in underground and superficial water based on researches made by authoress. As a result of stripping process outcomes were between 53,9 and 82,7%, lowest effects were achieved in III series – 44,8%. Observation was made, that during the process petroleum derivatives was removed gradually in III series, meanwhile in other series from the beginning high level of reduction was reached. Carried out stripping of petroleum hydrocarbons from water to air confirms relatively efficient method enabling lowering of their content to safe level. This process can be used to treatment of underground and superficial water with wide range of concentrations.
