Does anyone know if that the slower the water runs through di resin it lasts longer,only it was a while back i think i read a post about it,but i can`t find it,Gaz

[Moderator David@stives]

no it does not

[H h20]

no it does not

How do you know?

[gaza]

GAZ:I dont think is does,but if you tear as about in 1st gear in your car what happens? what does affect resin purification is if you get theor reverse the flow check them little arrows make sure you have the floww in the right dirrection.

I've found by minimising the flow through the DI cylinders they do appear to last longer.

I think this is due however to actually using less water per clean rather than the resin actually producing more pure water, but why use more water than you need to?

Can you believe it,i have just found the same post,and then someone else puts it back on,cheers,i also found a post by Williamx saying that if you run your water too fast through resin it increases the tds reading,Gaz.

[Moderator David@stives]

If the vessil is big enough you can have a fairly fast flow rate ,if your asking can it raise the tds then the answer is yes as the resin wont have time to do its majic if the flow is too fast for the amount  of resin in the vessil.
The resin only has a certain capacity to absorb the tds whether the flow is fast or slow it can not absorb more than its limit .
so the answer to you original question is no

How wierd is this , just seen my post dragged up again , and only tonight i did a resin change and have set up my contraption again , it was coming out at 15 tds and in my contraption im getting 000 again .
This has made my mind up to do what i wanted a while ago , use a di worth of new resin in my contraption to see what ammount of pure i get.
Normaly through my van mount i get 1200L from one di at 100 tds at tap , wonder what i will get through the P @ F filter system ! LOL

With tap water reading of 100 tds, you should be getting 5000 litres of pure water not the 1200 litres you are getting at the moment.

[P @ F]

William , the 5000 L that you are on about is for the whole bag isnt it ,
500,000 divided by TDS rule
The 1200 im on about is per vessel , i get 4 vessels per bag .

 Rich P @ F

[P @ F]

Just checked the machine and so far i have about 100 L of 000 TDS ,
Not bad for resin that was giving 15 TDS from the vessel .

You are right.

I have thought of a way to make the resin go further.  If you collect rainwater which normally has a tds reading of 20 tds, you then pump this though you di tank to get rid of these tds.

That way a 25 litres should produce 25000 litres of pure water instead of the 5000 you are getting.

I measured rain water last week that had collected on top of my containers, It was
000TDS. I measured it again coming from the downspout, It was 007PPM coming off a slate roof. Measured the TDS in a rain butt at my mates 27PPM off a felt roof. There are definate savings to be made using rain water if your DI only. Dai

[P @ F]

Yes , thats somthing i have looked at , its just a case of getting a 1000L ibc , i thought about getting some more butts but that would work out way too expensive

Unless it`s yellow 

[Moderator David@stives]

You can freeze water to deionize it .Dont quote me but i think the impurities get forced to the outer or inner ,cant quite remember.

That it then lets all chip in and hire a sea tanker and go to the north pole fill it up with snow and bring it back

[Moderator David@stives]

A technique used in most ice manufacturing plants that make large blocks of ice is to put a tube in the center of the container of water that is to be frozen. Through the tube they bubble a very low pressure stream of air. Before the tube becomes ice-bound, they remove it, and they pour or suction the water that is left in the center of the ice block away. All of the impurities -- dirt, dissolved air and minerals -- are forced into this water by the crystallizing ice. They fill the void with fresh water (or not) and continue freezing. The core of the block is clouded but the rest of the block is clear. If the core is not refilled and frozen, the entire block is clear
