Methods for reducing mercury content from a mercury-laden aqueous stream comprise contacting the aqueous stream with a tannin coagulant, a sulfide, such as a polyorganic sulfide, and an optional cationic flocculent. The invention is particularly well suited to reduce mercury content in mercury-containing wastewater streams of the type generated during oil and natural gas production.
