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.

Claim (Index 6):
A fluid composition comprising:\n a combination of oil and water, where the oil is produced from an oil field or where the combination of oil and water is a combination produced from an oilfield; colloidal silica, where the amount of colloidal silica in the oil and water combination ranges from about 0.5 ppm to about 200 ppm, and where particle size of silica in the colloidal silica ranges from about 0.5 to about 10 nanometers; and a chemical selected from the group consisting of aluminum brine dispersion polymers, alone or in combination with a dithiocarbamate (DTC), where the amount of the chemical in the oil and water combination ranges from about 1 ppm to about 1000 ppm.
