To destabilize finely dispersed oil-water emulsions and, as a result, to increase the efficiency of flotation treatment of ship bilge water, a reagent treatment method is used. The limiting factors in choosing a flocculant for preliminary reagent treatment of bilge waters should include the physicochemical characteristics of the oilwater solution. The paper presents the results of a study of the following physicochemical parameters of a solution of ship's bilge waters: the dispersed composition of contaminants, the charge of contaminant particles, kinematic viscosity, density and surface tension of the solution
ship bilge water, dispersed composition of contaminants, rheological properties
