DOI:https://doi.org/10.2172/6073113· OSTI ID:6073113

This report updates and expands on the scope of data presented in ORNL/TM-5926, published in November 1977. Since the previous report, overall plant equipment costs have increased approximately 7%/y and the costs of civil works and switchgear have increased at an annual rate of 7 to 8%. Operation and maintenance costs have increased about 7%/y. On average, the cost of desalting seawater by distillation has increased 25 to 30%. On a comparable basis, both electrodialysis and reverse osmosis costs have increased from 15 to 30% depending on plant size and feedwater compositon.
