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 850,000 gallons of permeate per day. It will have a fixed cost of $580 per day and an operating cost of $695 per day. A higher-pressure SWRO system operating at 800 psi will produce 950,000 gallons per day at a cost of $1,450 per day. The fixed cost of the high-pressure SWRO system will be only $324 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? gallons of blowdown water will require treatment each day for the two systems to break even
