The global water crisis is getting more and more serious, and desalination is recognized as one of the best ways to solve the freshwater crisis. At present, desalination has spread to more than 120 countries and regions around the world, and there are more than 13,000 desalination plants around the world, and the daily output of desalination is about 35 million tons, and it is increasing at a rate of more than 10% per year. Desalination has become one of the best methods to solve the problem of water shortage.
At present, the world's mainstream desalination methods mainly include multi-stage flash distillation (MSF), low-temperature multi-effect distillation (LT-MED), and reverse osmosis membrane method (RO). Each of the three methods has its own advantages and disadvantages, and the applicable conditions and scope are different. China mainly applies LT-MED and RO two methods, in the next few years, there will be a number of desalination projects on the horse.
China's desalination in the next 5-10 years will have a lot of room for development. China's desalination technology has matured after more than 40 years of research, the cost of equipment has been reduced by 30%-50% compared with foreign countries, and the cost of tons of water is close to the international advanced level. The large-scale application of desalination has a cost advantage, compared to the South-North transfer of tons of water cost is lower. The country has introduced a series of encouraging policies, and the scale of seawater desalination in the next 10 years will be 5 times the present.
Desalination equipment with titanium alloy instead of copper alloy is the future trend. Titanium's multi-faceted advantages determine the future in the field of desalination pipe widely used space, is expected in the next ten years, China's desalination titanium demand is about 9,500-23,520 tons, the global about 1,463-2,812,500 tons. Although the preliminary domestic demand is not large, the domestic demand only accounts for 1.6% of the total international demand, so it can be said that the overall development space is very huge.
