RO necessary ??

[Evowins]

Hi,

My Tap water TDS reading is 057. Do I really need to invest in a RO system or can I just use a di vessel to produce my pure water ??

...........taking into consideration that I am only WC on a part time basis at mo.

Any advice/tips very much appreciated.

Thanks, David.

You can just use DI at those levels.

If you did go RO - DI it would last an eternity at those readings.

What about at 100?

I am at 150ppm.

I use 2500L per week.

I run a 40/40 RO and a 25L DI. as well as Carbon and Sediment filters (cause they are cheap)

I change DI and carbon + sediment every six months and my RO membrane once a year.

Not cause I need to but cause it stays on top of it then.

I've just turned a shade of green /emoticons/biggrin.png

Mine's 400 often higher.

I'm the same tap at 400 plus 57 is after softener and RO. Then Di vessel to bring it down to zero. Changing resin every two months

Even at 400ppm with decent membranes you should have high 90s rejection rate so about 97% rejection rate would be 12ppm after ro..even 95% would give 20ppm after ro at 400ppm

57 is a bit high after ro

Maybe time to change membranes

I have a 450gpd ro and ppm fluctuates between 285 and 310

I also have good water pressure and my output is around 6ppm just from ro

I actually don't even use a di vessel as my water make up round here leaves no spots at that level
