There are two basic methods for breaking the bonds in saltwater: thermaldistillation and membrane separation.
现在有两种办法来断裂海水中的盐水化学键：热提溜方法和薄膜渗透方法。

Because the technology typically requires less energy than thermaldistillation, most new plants, like Tampa's, now use reverse osmosis.
由于这种技术通常耗费的能源较热蒸馏要少，现在大多数类似坦帕的海水淡化厂都使用反渗透技术。

Thermaldistillation involves heat: Boiling water turns it into vapor-leaving the salt behind-that is collected and condensed back into water by cooling it down.
