Abstract: A method of reducing silica fouling in an aqueous system is provided. The method includes adding a composition including a ferric salt and a magnesium salt to an aqueous medium to precipitate silica in the aqueous medium and form a precipitated silica. The method also includes removing at least a portion of the precipitated silica from the aqueous medium to form an aqueous supernatant.
