There are two basic technology categories for desalination systems: membrane/reverse osmosis and thermal distillation (evaporation). Thermal distillation is divided into three subcategories: MSF; Multiple Effect Evaporation (MED) and Vapor Compression. Most applications of titanium in the thermal distillation category are in pipes, valves, and water storage vessels. In contrast, titanium has limited use in reverse osmosis systems, mainly in pump heads.

The corrosion resistance of titanium is resulting from a tenacious surface oxide composed of titanium oxide. Commercially pure titanium, Grade 1, Grade 2, and Grade 3, exhibits excellent corrosion resistance to seawater at temperatures less than 130°C. In order to improve the crevice-corrosion resistance at higher temperatures, the modified titanium-palladium alloys are usually utilized covering Grade 7, Grade 11, Grade 16, and Grade 17. Another titanium alloy Ti-0.3Mo-0.8Ni is also often used. The titanium and its alloys have good resistance to pitting corrosion, hydrogen damage as well as erosion in a seawater environments. Titanium finds its most applications in the thermal distillation of seawater, used for tubing, valves, heat exchangers, evaporators, condensers, and other vessels, etc. Although the initial cost of titanium desalination equipment is higher than those of duplex stainless steel or copper alloy, the maintenance cost is comparatively much lower since titanium has a 40-year history in use without replacement according to engineering practice.
