Discussion Overview

The discussion revolves around methods for converting salt water to fresh water on a large scale. Participants explore various technologies and chemical processes that could facilitate this conversion, focusing on practical applications rather than theoretical concepts.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about machines or chemicals capable of converting salt water (8.8lb-9.4lb) to fresh water (8.6lb) in large quantities, expressing dissatisfaction with solar evaporation methods that yield only a liter per day.
  • Another participant mentions reverse osmosis systems and flash distillation as common methods, suggesting that solar-based systems may be effective in equatorial regions.
  • A suggestion is made to pass an inert gas like argon through boiling saltwater to potentially enhance the vapor transfer rate.
  • One participant indicates they have searched for solar-powered systems but has not found suitable options for their application involving a large tank of approximately 2000 gallons.
  • The same participant expresses interest in finding an inline filter system that could work with their pump to facilitate the conversion process.
  • There is a repeated inquiry about large-scale conversion methods, emphasizing the need for a solution that does not necessarily produce drinking water but approximates the weight of fresh water.
  • A link to a desalination resource is provided, although its relevance to the specific needs of the participants is not established.

Areas of Agreement / Disagreement

Participants present multiple competing views and methods for desalination, with no consensus reached on a single effective solution for large-scale conversion of salt water to fresh water.

Contextual Notes

Participants express varying degrees of familiarity with existing technologies and their applicability to specific scenarios, indicating potential limitations in the solutions discussed.

Any one know of a machine/chemical to convert Salt water (8.8lb-9.4lb) to Fresh water (8.6lb) on a LARGE scale?? I have read several things on converting using the sun to evaporate the water, but that's only like a liter a day. I would love to find something or have something made that would convert on a lot larger scale (Gallons or hundreds of gallons/day). How much would be possibe? Even if a generator would be used continuously to do so. It doesn't need to be drinking water. Just approx the weight of FRESH WATER.
- OR a chemical that would make Salt Sink in a large container so that the Fresh Water could be pulled out. ?

Anyone??

Thanks!

Well there are reverse osmosis systems, but I think flash distallation is pretty common, and solar based systems would be ideal in equatorial latitudes.

Passing an inert gas like Ar through boiling saltwater might facilitate the vapor transfer rate.
 
Did you try a google search on desalination?

Thanks! Sorry for the multi-post, wasnt sure on where to put it. I have been searching google before I posted. I found several solar powered systems, but not really for my application. I am dealing with a large tank with approx 2000 gallons of water and have a pump that transfers it to other tanks, I would like to fnd some sort of filter system to put inline to filter as I am pumping, and then maybe do it again. The pump will transfer plenty fast. Thanks for the help!

Is this large enough?
