Purification of Waste Water from Petroleum Products with the Use of Combined Sorbents

The results of the study on the purification of model water from petroleum products with the concentration of 15 to 100 mg/dm 3 with the use of polyethylene foam (PE foam) and polypropylene foam (PP foam) polymer chips a well as the carbon ABZ sorbent as sorbents were presented. The sorption process was carried out under dynamic conditions. The model waters were purified with PE foam and PP foam polymer chips, the purification efficiency was up to 91%. To increase the purification efficiency of model waters from petroleum products, the model solutions were purified from petroleum products through a combined loading - PE foam chips and ABZ sorbent. It is shown that the use of a combined loading allows to reduce the concentration of petroleum products in waste water to standard values. The results of chromatography - mass spectrometric analysis confirm the high efficiency of waste water purification from petroleum products.
