A low-pressure seawater reverse osmosis (SWRO) system will operate at 500 psi and produce 725,000 gallons of permeate per day. It will have a fixed cost of $510 per day and an operating cost of $725 per day. A higher-pressure SWRO system operating at 800 psi will produce 950,000 gallons per day at a cost of $1,475 per day.
