Costs of getting rid of minerals from water
Costs of getting rid of minerals from water
(OP)
Please let me know if it is possible to use the reject water from reverse osmosis (contains 4 times more minerals than normal potable water) and get process water (I assume something like distilled water) with 0% minerals.
How much would it cost to erect one plant capable of producing 240m3/day( 912gal/day).
How much would be production costs per gallon?

Sorry, I got no idea how much would your gallon of distilate cost, depends on too many details.

Please take note that 240m3 is equal to 63360 gallons(US).
So the flow is 10m3/hour or 2.78 l/s or 44gpm.
I do not have any experience with reject water but I had a desalination plant in one 20 foot container and the capacity was 200m3 per day. How close are these two operations? Should there be a huge price difference?
Thank you and have a nice day.

I rushed in with my comment, without checking the figures, you just did. I will come back with details for your plant shortly.

You should scope out the type of process you would like to use and then try to quantify the costs.
RE: Costs of getting rid of minerals from water
If you have RO reject water with such high salt content that it is not acceptable for any water use, you should look into an evaporation process such as a brine concentrator. The evaporation process uses heat, waste heat, or electricity to concentrate the RO reject to a brine stream. Distilled water is produced as a byproduct.
You might be better off posting on the water forum.
