Everybody ,How can make pure-water from salty-water for agriculture?

Question

Salty-water is from well with 25 liter/seconds DBI.

Answer 1

distill it...ü

Answer 2

1. Filter it

2. Leave it in the sun; cover with something with small holes in it(ie colander, flywire) so the salt can evaporate

Answer 3

Boiling would work, but would be energy intensive.  Reverse osmosis is a little better, but would still be energy intensive.

A solar powered reverse osmosis desalination plant would work to remove salts powered completely by the sun.  Australia has developed one for desalination in remote areas of central Australia (first link).  However, I could not find numbers as to the desalination capacity (i.e., process rate).

A basic solar still would work to provide small quantities of clean water, but would be impractical for anything but small agricultural usage.  Another alternative, similar to the solar still would use the M-E-H method for desalination (second and third link). The mid-level unit will provide up to 5,000 liters per day of clean water (<50 ppm salinity).

Answer 4

Evaporation, using a still.....

a solar still is the cheap way

Answer 5

Process is simple, boil salt water, separate water vapors and cool, you have pure water.

Implementation is hard and not economical.

What can be done is, make some solar panels and heat up salty water in a closed container, separate vapors and cool them.

Equipments may not last for very long, in about 4 to 6 months you may have to replace them.

ask the israelis and if they're in a good mood they'll tell you. better still read this article.  http://deadseapower.com/irrigation/
