This slide presentation outlines information on using reverse osmosis (RO) for desalination. Topics covered include: explanation of the RO process; types of RO membrane currentlyavailable; explanation of osmotic pressure; dissolved solids concentration (salt)of various seas; standard seawater quality; osmotic pressure of seawater; theoretical power requirement forSWRO; osmotic pressure of brine; theoretical vs. actual energyconsumption; RO system; comparison of various RO system configurations with respect to energyconsumption, and feed & brine flows; SWRO system; 2 stage with brackish water andseawater elements; reduce flux - lower energy comsumptionand less fouling; RO feed pump and motor efficiency; energy recovery example; energy recovery devices; and, decrease of total power requirements. Includes tables, figures.
