一些采取蒸馏海水的方法，通过将海水加热，蒸发出部分海水，之后将其浓缩，而这一方法需要电力。
Some distil seawater by heating it up to evaporate part of it. They then condense the vapour-a process that requires electricity.
一种方法是海水蒸馏，通过加热卤水可以得到浓缩的水蒸气，这种方法每淡化1立方米的海水需要10千瓦时的电量。
Some employ distillation, which needs about 10 kilowatt-hours (kWh) of energy per cubic metre of seawater processed. Brine is heated, and the resulting water vapour is condensed.
海水脱盐法不可避免地遗留下浓缩的盐水，它会破坏环境，甚至影响淡水供应。
Desalination inevitably leaves behind a concentrated brine, which can harm the environment and even the water supply itself.
海水经浓缩后我们得到盐。
膜蒸馏是一种新型的膜分离技术，可用于海水淡化、纯净水制备、热敏物料浓缩等方面。
Membrane distillation (MD), which has been applied to purification of water and concentration of thermally labile substances, is an innovative membrane separation technique.
