Two membrane systems are under consideration for treating cooling tower blowdown to reduce its volume. A low-pressure seawater reverse osmosis (SWRO) system will operate at 500 psi and produce 720,000 gallons of permeate per day. It will have a fixed cost of $465 per day and an operating cost of $485 per day. A higher-pressure SWRO system operating at 800 psi will produce 950,000 gallons per day at a cost of $1280 per day. The fixed cost of the high-pressure SWRO system will be only $328 per day because fewer membranes will be required. How many gallons of blowdown water will require treatment each day for the two systems to break even?
