Title: Water produced from 100% seawater

Water produced from 100% seawater


 I wondered when people may start to produce drinking water from seawater and now I see it's already not just a dream; I had one bottle of water produced from 100% seawater:

Alkaline Ionized Water
  • High quality water produced from 100% seawater.
  • Alkaline ionized water is beneficial for health.
  • Excellent for preparing any drinks with rich taste.
Net Content: 850ml
(In Chinese: '海洋碱性离子水'.)
 The taste of this water is good. If I have to drink only this water, I'll feel not bad. What I mean is: tastes like the other water I drank and drink. :)

They've been doing seawater to fresh water conversions for a long time now. You just don't hear of it because you haven't been exposed to it.

The first  thing you should know is that compared to getting fresh water from the ground table, a stream, or artesian well, making fresh water from salt water is expensive as a process. You do it when you don't have a choice in the matter of where the water comes from. When expense is not as important as the availability of water. The main methods for extracting fresh water are either vacuum or osmosis.

There is another method that has been used called the condenser method but it's not as popular a method as it is slower to obtain a volume of fresh water. The advantage of the condenser method is it doesn't need a water source to start with. It pulls the water out of the air.

No matter if you use the vacuum method with a heat source or if you use the osmosis method, chemicals and maintenance are involved. In the osmosis method, there is a further expense of the membranes that are essential to the conversion. They aren't cheap. One such unit I used to work on took 6 membranes for the unit and were to be changed out every 3 months. The chemicals are for back flushing to prevent a buildup of minerals found in the seawater. It's a must if you expect your water maker to continue to produce the same volume. Ignoring maintenance means that the water maker will make less and less water until it fails.

 I meant "why people may start to produce it AND TO SELL IT" (but I didn't express my meaning well). This is the first time I see this water for selling (all I heard before was that it's a very expensive, as you said, procedure, so probably nobody wants to sell it.) This bottle of water really is more expensive than the others, but the difference is not very 'terrible' :).
 Thanks for mentioning about

I saw on the news that someone already sells a small thing that people may use, if they live in deserts and places without drinking water. Can't find it online now, but it was interesting, because it was pretty compact (small and convenient). I couldn't find it, but I found something related, maybe you will like to take a look: https://grabcad.com/challenges/countertop-atmospheric-water-generator

Somewhere I have the plans on how to make a homemade water condenser. It's not on my HDs so that means I've transferred it to a NAS. Might take me some time to find it but if I do and you are interested I could host it for download if you want it.

Yes, please! If you find it, let's see it. Thanks a lot in advance!
