Abstract

Embodiments of the invention enhance the performance of the seawater reverse osmosis systems by incorporating unit processes upstream that reduce the scaling tendencies of seawater. Additional embodiments improve the water balance for the overall system by recovering a substantial fraction of the seawater reverse osmosis brine that otherwise would have been discharged as wastewater, in the form of pure distillate for either blending with the seawater reverse osmosis permeate or direct industrial use. Embodiments may include further processing steps to convert the seawater reverse osmosis brine into a commercially reusable product, minimizing wastewater generation and optimizing the cost benefit aspects of the overall system.
