Abstract：In order to resolve the corrosion problem of high-salt concentrated water from reverse osmosis system, based on the characteristics of high-salt concentrated water, the corrosion mechanism was introduced. The influences of five factors (dissolved oxygen, total dissolved solids, pH, temperature, flow velocity) on corrosion behavior were analyzed. Three common corrosion prevention technologies (electrochemical protection technology, surface treatment technology and corrosion inhibitor) were discussed, as well as their advantages and disadvantages. In the end, some suggestions were put forward towards further research on this issue.
