Elaboration of the efficient technology of contact cleaning of wastewater from mineral oil

Complex investigations on development of efficient technology of contact cleaning of wastewater from oil pollution was carried out. This technology is based on processes of sorption, ion exchange, and subsequent sedimentation. It is shown that modified sorbents prepared on the basis of cellulose, polygorskite, and activated carbon effectively clean water from oil and oil products, where the degree of cleaning reaches over 98–99%. It is found that the sorption coefficient (K _a) increases with the increase in the dispersity of sorbents, and the consumption of sorbent (g/100 ml) decreases.
