Abstract: A method of producing barium sulfate with a barium sulfate production system includes introducing an amount of a sulfate contaminated water to an agitation unit of the barium sulfate production system, introducing an amount of a barium source to the agitation unit, thereby forming a treatment mixture, and agitation the treatment mixture to promote ion association between barium cations from the barium source and sulfate anions, thereby producing a barium sulfate precipitate and a treated water. A barium sulfate production system includes an agitation unit in fluid connection with an aqueous fluid feed line, a treated fluid outlet and a precipitate outlet, a sulfate contaminated water unit in fluid connection with the aqueous fluid feed line, and a barium source.
