Dirty Saltwater And RO

[dtefft2023]

I was wondering if anyone has tried cleaning the dirty saltwater from an aquarium water change using an RO system. Generally, not a lot of water and might not be worth the expense; however, I have a 240-, 130-, and 60-Gallon setup and will probably add some more and would prefer not to dump saltwater outside or into a Septic system.

I'd have to imagine the rate filters would be clogged and needing replaced would be staggering

I’m sure brs or spectra pure would love that concept

Saltwater RO systems run at about 800 psi. Let us know when you're ready and we'll fix you up

What would be the goal? To make clean fresh water from water change water?

You'd still be dumping out the salt that was rejected by the RO.

A typical family of Four use 400 gallons of water a day, a mere drop in the bucket from your Aquarium .Also when you make new RO/DI water, more water is flushed down the drain, than the amount of Saltwater. I’ve used my discarded water for other purposes, weed killer on my Driveway Stone border. Killed the Bradford Pear weed trees, off. Used it mixed with Vinegar to kill poison ivy. Killing the Greenbrier Vine Tuber. Pre-treatment on driveway before a snow storm, and it’s even killed mold and algae off of concrete.

I am not sure it would be cost-effective, but I am interested to see how others who have more experience than me respond.

You are basically talking about Desalination Unit.
You can do it, for close to $4K you can get marine desalination unit for small boats, making 40Gal freshwater/h from sea water.
I agree, though, cost, both in terms of money, but also environmental costs would be rather prohibitive.

I think the question is resolved as not being of any practical utility.
