Wastewater Treatment with the Natural Sorbents from the Arctic

Oil and gas production has an adverse impact on the ecological state of the Russian Arctic. The local natural materials, such as peat, moss, and reindeer moss are considered as naturel sorbents in wastewater treatment technologies. The sorption properties of these local materials were studied. The sorption isotherms at different initial concentrations of the pollutant (250, 50, and 0.5 mg/L) were constructed. The patterns of changes in the sorption intensity of oil products were determined. The sorbents were modified by microwave radiation (600 W, one minute), which had a visible positive effect on the samples. Preliminary calculations of the filter cassette dimensions with the performance 200 m3/day were carried out. Efficiency and cheapness predict the economic feasibility of using these materials in wastewater filtering equipment.
