These membranes are based under the principle of reverse osmosis.

这些膜基于反渗。

Now reverse osmosis, it's the reverse of this natural process.

现在反渗，它是这个自然过程的逆过程。

In cooking at home, steer clear of non-stick cookware and filter your drinking water with activated carbon or reverse osmosis, if possible.

在家烹饪时，避免用不粘锅，并用活性炭或反渗过滤你的饮用水，如果可能的话。

KEITH HINKLEY, PRESIDENT OF PLAQUEMINES PARISH: You've got one trailer would be the reverse osmosis and the other would be the filtration system right there.

已经知道拖车是反渗的另一个是过滤系统。

So, in total, using reverse osmosis and nanofiltration membranes, we can convert industrial wastewater into a resource of both water and salt.

因此，总的来说，用反渗和纳滤膜，我们可以将工业废水转化为水和盐的资源。

Next, the water passes through an even finer reverse osmosis membrane, which can remove particles as small as a tenth of a billionth of a meter.

接下来，水会通过一层更细的反渗膜，它可以去除小到十亿分之一米的颗粒。

36. So in addition to the interlocking underground rhizomes, they have yet another adaptation and it's, well, we're back to reverse osmosis again.

所以，除了相互铰链的地枝外，它们还有另一种进化… 嗯，我们还是回到反渗吧！

So instead of fresh water moving out of the plant cells, salt from the seawater enters, reverse osmosis, and this actually strengthens the cells.

所以不是淡水细胞中流出，而是海水中的盐分进入， 反渗，这实际上加强了细胞。

18. So instead of freshwater moving out of the plant's cells, salt from the seawater enters, -reverse osmosis- and this actually strengthens the cells.

这样的话，海水不仅不能抽走它的水分，反而还要进入到它的体内，这就是所谓的反渗，这种能力增加了细胞的强度。

One way to get around this problem is to remove salt from sea water with reverse osmosis, a process that separates water's ingredients by size.

解决这个问题的一种方法是通过反渗去除海水中的盐分，这是一种按大小分离水成分的过程。

So using reverse osmosis, we can take an industrial wastewater and convert up to 95 percent of it into pure water, leaving only five percent as this concentrated salty mixture.

因此，用反渗，我们可以将工业废水中的 95% 转化为纯水， 仅留下 5% 作为这种浓缩的含盐混合。

Take the drought-prone Tri-Valley area of Northern California, which in the late 1990s built a multi-million dollar water plant that used reverse osmosis to recycle sewage water into drinking water.

以北加州干旱多发的三河谷地区为例，该地区在 1990 年代后期建造了一座耗资数百万美元的水厂， 该水厂用反渗将污水回收成饮用水。

She recommends using a glass bottle when you're on the go, and filling it with water that has gone through a reverse osmosis filter, which can help to remove the microplastics in tap water.

她建议外出时携带玻璃瓶，并装入经过反渗过滤器的水，这有助于去除自来水中的微塑料。

Sap has 2% sugar, concentrate has 20% sugar, so what we're doing in the reverse-osmosis process is we're pulling water out of the sap and concentrating the maple syrup into another solution.

树液含有 2% 的糖分， 浓缩液含有 20% 的糖分，所以我们在反渗过程中所做的就是将水树液中抽出， 并将枫糖浆浓缩到另一种溶液中。

It's like you're looking at a fire (a metaphor for your financial problems), and you're running around scrubbing the fire hoses, polishing the nozzles, and setting up a reverse-osmosis filter for the water supply.

这就像你正在看着一场火灾（比喻你的财务问题）， 你正在跑来跑去擦洗消防水带， 抛光喷嘴，并为供水设置反渗过滤器。
