Abstract
In one aspect, systems and methods for the efficient and cost-effective removal of bromide from wastewater streams are described herein. Briefly, a system for bromide removal comprises pretreatment apparatus operable for at least partial removal of background ionic species from the wastewater stream and/or dilution of the background ionic species in the wastewater stream. The system also comprises bromide capture apparatus operable for removal of bromide from the pretreated wastewater stream, wherein the system removes bromide from the wastewater stream at an efficiency of at least 80 percent. In some embodiments, bromide is recovered from the capture apparatus and reused in flue gas treatment applications.
