R.O. Water in Concrete Tank

[steve569]

If R.O. Concentrate water was stored in a pre-cast concrete tank would it be corrosive to the tank its self or would it draw minerals from the concrete that would cause it to have a higher TDS reading. Thank you for any response.

Years ago I used to put together RO units. I was always told that RO water ,because it was starved for minerals is very aggressive. We always use fiberglass tanks below ground,and plastic above ground.

Because I have never seen it stored in concrete,I can not directly answer your question ,but you could very well have some issues with storing it in concrete (in theory anyway).

You could probably line the concrete tank with something to protect it and the water, or you could just put a plastic tank in. You wouldn't be able to store RO water in concrete.

You said "RO concentrate water," do you mean the RO reject or the actual usable product?

I know of two underground concrete RO product water tanks. As far as I know neither has had a leaking issue. One has been in service for at least 8 years and for some reason, has large stones sitting at the bottom of the tank (maybe done to to sink the tank?). I would not recomend using concrete RO storage tanks.

I wouldn?t a concrete tank for RO water. If you want to put a R.O tank in the ground use a plastic Septic tank.

I meant the accual usage water.
