My major.

I major in thermal energy engineering, and my research subject is seawater desaliantion desalination utilizing multi-effect distillation.You may ask that why you chose this for your research suject? You can see the date as follow Here's why:only 0.25% of the water in on the earth is fresh one, water and among which that, no more than 1% can be used directly, .wWhat's more, in 2025, 3,000,000,000 people will live in the with a shortage of fresh water. That's why how to get make pure water from sea water is a focus topic in the filed of water treatment, because of the serious reduction of the water resourse.
