Cost analysis of seawater desalination using an integrated reverse osmosis system on a cruise ship


GULEDA ONKAL ENGIN et al. View all

Water and Wastewater Treatment

The best method to treat seawater is known to be the use of reverse osmosis (RO) systems. The cost factor becomes the most important issue when using RO systems. Although quite costly, RO systems are essential systems for ships. As known very well, water is a critical resource on ships, especially...
