Abstract

Integrated processes for the treatment of produced water, including for example treatment in connection with hydrocarbon production operations using bulk solid-liquid separation, organics removal, and desalination by osmotically assisted reverse osmosis (OARO) and/or vacuum membrane distillation (VMD). Various pretreatment technologies including without limitation pH adjustment, oxidant addition, particle removal, oxidant removal, followed by OARO and/or VMD, may be combined with a subsequent polishing process of the desalinated produced water such as to remove ammonia, boron, heavy metals, and/or organics. Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be sent for beneficial reuse which includes without limitation different fit-for purpose applications including those outside oil and gas industry at a low cost.
