RO/DI filter....really????

[kylejordan]

I've got a home made DI Filter, RO is nice but I find it unneccesary, my filter litterally cost me like 55 bucks for filters chambers and plumbing, and my TDS is 13ppm going in and 0 coming out! most of the parts you can get from Rona or Homedepot and the filters you get from your LFS. mine is 2 chamber large particle filter followed by DI, it runs fast clean and quick!

I think i will agree with this. I have a 4 stage RO/DI and the waste water is just crazy not environment friendly. I read couple of articles too that RO and DI does same thing. So on the weekend i tried disconnecting the RO, then install the TDS meter after DI and this was the result:
Before: IN- 13 OUT- 0
After: IN- 12 or 13 OUT - 0 or 1
less waste and good for the environment. hopefully it will work out..
Just my reaction...\\

Same sort of result but not the same thing, and there is a lot of stuff the ro strips out that a DI won't touch.

RO strips all the minerals/chemicals out of the water and leaves you with nothing but pure water. DI is a Ion exchange process where salts are replaced with Hydrogen making your water acidic and then the next resin makes it normal.

in industry where DI is called for is polishing ro water as a DI doesent remove a lot of the contamanants so you use the RO to remove the bulk and then a DI to remove anything else. on its own a DI will not last very log at all.

We used DI water for out boilers as it has to be absolutly cleen water, but the water went through a RO first down to about 5ppm then went through a two stage DI, mixed bed resins are very inefficient, the best way to do it would be to have one resin then the next resin in a different cartrage.

Thanks for another good information. But i am going to try it anyway, my water bill went sky rocket because of the waste water...

realy?? how much water were you making? I was going over 50 gal per week in victoria and my water bill never changed at all. you must have an awfull high water consumption to start with..

Must be nice to have water going in that isn't at almost 200 TDS to start .

+1, perfect info in there.
