Abstract
The combination of colloidal silica in conjunction with a chemical, such as a cationically-modified water soluble polymer, e.g. aluminum brine dispersion polymer, clarifies combinations of oil and water, for instance wastewater comprising an oil-in-water emulsion. The colloidal silica may have an average silica particle size of about 0.5 to about 10 nanometers.
