Good for Egypt. This is something California could use.


EGYPT HAS DEVELOPED A GAME-CHANGING LOW-POWER WATER DESALINATION TECHNIQUE
By Kelly Hodgkins — October 24, 2015





About 71 percent of the Earth’s surface is covered by water, but unfortunately most of that liquid nourishment isn’t suitable for drinking because it’s salt water found in the oceans. Removing salt from water is not an easy process, either. Current desalination technology requires a high amount of energy, making it prohibitively expensive — especially in developing nations. But don’t worry: a team of researchers at Alexandria University in Egypt have bypassed these power-hungry methods and created a simple filtration technique; the details of which are described in a research paper published last month in Water Science and Technology.

To remove salt from water with minimal power, the researchers use the process of pervaporation, in which salt water is first filtered though a membrane to remove larger particles. These filters contain cellulose acetate powder that, along with other components, will bind the salt particles as they pass through the membrane. Made from materials common to Egypt and surrounding countries, the filters are affordable and can easily be produced in a laboratory setting.

Still more expensive than buying bottled water.

Next...

Nuttin' personal but I wooden wanna drink water out of your cup, H.

I read more. The language is very strange. For one thing it talks both of 'larger particles' removed by the membrane and then 'salt particles' which one would have assumed to be in solution.

Then it says the 2nd part of the process is distillation so what is the point of the whole exercise, lowering the boiling point of the solution to be distilled?

That's ok. It has holes in it anyhow...

Since I am not a scientist, especially one who deals in something like this, perhaps you can assist them with your expertise. It's like there is a water reclamation plant not that far from me that uses waste water from the toilets to fill up a man-made lake and water the grass and trees around the lake. I don't concern myself with how it works. I leave it up to the experts. All I know is that California is in the middle of a drought, and anything which can help alleviate the water shortage is a help. In fact, there is plenty of drought throughout the Middle East so any country which comes up with something to help will be appreciated.

I don't believe anyone can assist journalists, what they think they don't know isn't worth knowing.

How about the following is said about you?

"What YOU think you know isn't worth knowing."

Regardless of what you think of Egypt's project, at least they are trying to do something. What have you come up with lately to alleviate droughts all over the world? When you come up with something or even attempt to come up with something, then you can criticize what Egypt is doing. I am happy that there are scientists and other researchers in other countries willing to try to come up with different methods to help those countries who are experiencing drought conditions.

 

[cnm]

I only wish I could understand the point of the process.

But you seem confused, as though I attacked Egypt when in fact I criticised the article. Still, that is your normal behaviour from what I've seen.

Was it really that difficult for you to just give Egypt credit for trying to do something which would help with drought conditions whether or not you understood the process? I don't understand the method they use since I have no education nor experience in it, but I do respect the country for trying.
