Background
With the development of the economy of each country, the problems of water resource shortage and water pollution are more prominent. At present, about 11 hundred million people live and lack water all over the world. Data show that the total water storage of the earth is about 14.5 hundred million cubic kilometers, with ocean water accounting for about 96.5% of the total water storage of the world, surface water accounting for 1.78% of the remaining water, ground water accounting for 1.69%, and fresh water mainly utilized by humans accounting for only about 2.53% of the total water storage of the world. Therefore, the problem of water resource shortage is relieved by fully utilizing seawater desalination.
There are two main methods for desalinating seawater, namely, distillation and reverse osmosis. A reverse osmosis membrane technology which utilizes natural water column pressure difference to replace a high-pressure pump in the deep sea field appears at present. The technology can make full use of the characteristic of higher pressure of the deep sea bottom, not only can save the power consumption and the pretreatment cost, but also can save the cost of membrane replacement, and has lower water production cost. However, energy is also consumed in transporting the fresh water produced in the deep sea to the sea level. The traditional method is to use a water pump for conveying, which is simple, but consumes a large amount of energy, increases the cost and causes serious equipment loss.
