Methods and additives for reducing fouling in water coolers in Steam Assisted Gravity Drainage systems (SAGD) are described in which an additive comprising a cationic starch, either alone or in combination with a water clarifier compound, is introduced into a SAGD system, wherein a lower amount of the additive is used to achieve the same or better results in reducing fouling in the water coolers as compared to an otherwise identical method absent the additive.

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.
