Abstract: To optimally mix treatment additives to a contaminated liquid, treatment additives are selected. A mixing energy requirement of the contaminated liquid and treatment additives is then determined by mixing the treatment additives over a range of time and mixing speeds, and measuring turbidity to determine the mixing time and speed which results in the lowest turbidity. A low mixing energy requirement requires a lower mixing time and mixing speed than a higher mixing energy requirement. The contaminated liquid and selected treatment additives are then directed into a mixing system including at least one hydrocyclone. Each hydrocyclone has an inlet aspect ratio, a barrel length and diameter selected based upon the mixing energy requirement determination. Altering the aspect ratio, diameter, and length of the hydrocyclone results in different mixing speeds and mixing time, which can be optimized for the given contaminated liquid and treatment additives.
