Reverse osmosis (RO) is a proven technology for the removal of high concentrations of total dissolved solids. One of the major challenges of any RO system is the disposal of the brine, or concentrate, which is produced during normal operations. The treatment of brine is typically undertaken to minimize the cost of disposal or to maximize the recovery of treated water (RO permeate). Selection of brine treatment technologies is based on the constituents in the flow stream. This paper will present a global perspective on the treatment options available to process brine streams and examine two case studies from the Southwestern United States where technologies have been applied. General treatment costs will be provided, along with a discussion on the incorporation of brine treatment into a full-scale design.
