Extraction of petroleum products from wastewater by natural sorbents of the Arctic

Abstract

Oil and gas production in the Yamal-Nenets and Khanty-Mansi Autonomous Okrugs has an adverse impact on the ecological state of the Arctic. In order to prevent pollution of northern water bodies with oil products, local natural materials (peat, moss and reindeer moss) are considered as sorbents. Sorption isotherms were constructed for different initial concentrations of the pollutant (250.50 and 0.5 mg/dm3); regularities of changes in the intensity of sorption of oil products are determined. The sorbents were modified by microwave radiation, which had a noticeable positive effect on reindeer moss samples. Based on the data of a laboratory experiment, the design parameters of filter cassettes were calculated. Efficiency and low cost suggest the economic feasibility of using these materials in wastewater treatment technologies.
