SYSTEMS AND METHODS FOR REMOVAL OF BORON FROM WATER, SUCH AS OILFIELD WASTEWATER

摘要

Described herein are systems and methods for removing boron from water. According to certain embodiments, an aqueous input stream comprising boron and at least one suspended and/or emulsified immiscible phase is supplied to a water treatment system comprising a chemical coagulation apparatus, a suspended solids removal apparatus, and a boron removal apparatus. Within the chemical coagulation apparatus, an amount of an inorganic coagulant, an amount of a strong base, and an amount of a polyelectrolyte may be added to the aqueous input stream to form a chemically-treated stream. In some embodiments, the chemically-treated stream, which may comprise a plurality of floes, may be directed to flow to the suspended solids removal apparatus. Within the suspended solids removal apparatus, at least a portion of the floes may be removed from the chemically-treated stream to form a contaminant- diminished stream having a lower concentration of contaminants than the aqueous input stream.
