Abstract: This technology evaluation was prepared by Pacific Northwest National Laboratory on behalf of the U.S. Department of Energy’s Federal Energy Management Program (FEMP). ¬The technology evaluation assesses techniques for optimizing reverse osmosis (RO) systems to increase RO system performance and water efficiency. This evaluation provides a general description of RO systems, the influence of RO systems on water use, and key areas where RO systems can be optimized to reduce water and energy consumption. The evaluation is intended to help facility managers at Federal sites understand the basic concepts of the RO process and system optimization options, enabling them to make informed decisions during the system design process for either new projects or recommissioning of existing equipment. This evaluation is focused on commercial-sized RO systems generally treating more than 80 gallons per hour.¬

Performance advancement in the spiral wound RO/NF element design
TL;DR: In this paper, spiral wound element improvements have been made so that RO/NF products are more robust, and the design of vents in the seal carrier or ATD's on the ends of the elements has proven to quickly equalize the pressure on the inside of and outside of the element and prevent rupture of the FRP shell.
