Oily Wastewater
An oily waste emulsion, in which oil is dispersed in the water phase, may contain any one of several types of oil in a wide range of concentrations. In addition to oils, typical contaminants of these emulsions may solids, silt, metal particles, emulsifiers, cleaners, soaps, solvents, and other residues. the type of oils found in these emulsions will depend on the industry. They may be fats, lubricants, cutting fluids, heavy hydrocarbons such as tars, grease, crude oils, and diesel oils, and also light hydrocarbons such as gasoline, kerosene, and jet fuel. Their concentration in the wastewater may vary from only a few parts per million to as much as 5-10 percent by volume. Treating the emulsion is usually accomplished using coagulants dosed at an appropriate level to neutralize the electrostatic charge.Our experienced team can help you determine the program that will work the best for your oily wastewater treatment application.
