A technology for sorption post-treatment of oil-containing water from ships using natural materials has been developed. In the course of work, the following natural sorbents were investigated: shungite and mont-moril-lonite. The parameters of the process of static and dynamic sorption of petroleum products from a solution of ship bilge water have been determined. It has been found that montmorillonite is the most effective material for the sorption of fine particles of petroleum products. A mathematical model of the dynamic sorption process has been developed, which makes it possible to determine the cleaning efficiency depending on the initial concentrations of oil products in the solution and the cleaning mode.
