sorry mate we have been discussing this on another post aint we i dont know what the "freedom" set up is like so cant say for sure some one (maybe peter f) said about merlins giving a high tds out of ro,so i assume different systems behave differently,maybe ,regardless of this my tds in is higher and out is lower with no booster.Marcus uses a booster but he has lower mains pressure than me ,he still gets a higher production rate than me while using the booster with similar tds from tap.Personally i think you have something playing up,its just finding out what tho

[Moderator David@stives]

I have used over a thousand pounds of resin this year.

Time to get an RO me thinks

[dave0123]

   and il never find out if there is something playing up lol because am new to all this.


without the booster pump my tds out of ro was about 30-31 am now thinking of just getting a merlin   because il get more water out of the system in less time.

i have my booster pump after the prefilters i spoke to ro-man other week he said it works better before the prefilters the one on his site for 74.00 i think it is.. so i mite try that but dont think it will make much diffrence. Also the booster pump is quite loud but if i flush the system with the pump on doesnt half make less noise

when i run the RO i can hear a little hiss? could be air am not sure is that normal if anyone with a purefreedom RO has the name.

Dave are your DI's in the vans or filling statics at home?

Tony

[dave0123]

i have one 11lit,

its at home filling 1000lit because i use a trolley at the moment otherwise would be in van

heres a pic of the setup

[Moderator David@stives]

Tony

I fill through 3 DI vessils at home at the moment, I have took all filter systems out of the vans, to many issues to deal with so kept the vand simple.

Dave

Do you have full mains pressure going through the DI's or is it toned down to a steady flow? How big are the DI's?

Tony

[dave0123]

ah sorry i replied to a post for another dave

[L.J.Thorpe]

that looks same as ro-man ,its a 200gpd then .Dont know mate ,filters maybe ???too new tho surely,mains pressure ???booster should sort that....strange you seem to be doing everything right

[macmac]

ah sorry i replied to a post for another dave

Yep, no good asking me about RO's

Tony

[dave0123]

its a 300 GPD Has 3 filters on the top one you carnt see its hidin by the other two.

thats what i thought the booster pump would sort it even if the mains pressure was low!    the sytem has only been running for about just about 6 weeks

[Moderator David@stives]

 mains pressure, about 600 litres an hour

no idea mate,hard to do this sort of thing if not there to see it first hand ,the sediment filter in that pic looks nice and clean ,so i cant see it being knacked(mine are chocolate brown when replaced )cant help on this...sorry

That could be why you're going through so much resin mate, the resins that we buy for wfp are not efficient at such flow rates, there are other resin types available that work better at higher flow rates. I would suggest you turn the flow down to at least half that or less & see the difference
After all, you've nothing to lose as if you go for an RO you'll be producing water at less than this rate anyway. I know foxman will dissagree but purolite is the worst preforming resin i've used & dowex the best but i have my DI's in the van (2 x 11Ltr) so the flow going through them is minimal. I'm no resin professor but i'm pretty sure the lower you can get the flow through your DI's the more efficient they will be. If you search on the net you'll get technical data for resins & see for yourself about the flow rate affecting them.

thats flow tho is it not   somebody should be able to calculate the pressure tho based on 10 lpm and 13mm pipe(thats metric for half inch aint it )

[dave0123]

Thanks thorpe!

yer it hadnt been used when this pick was taken but it still looks the same!

how many things could it be? loads and loads or one or two? because i could look into it abit more. what i mean is .. is it just something silly like prefilters not a major problem

hmm i spose you wont no. i dont no what to do haha.. thanks anyway

get the ro ,will slow flow considerably and tony is right if that 10lpm going straight through a di THATS why you using so much resin

[dave0123]

Oh one thing it does do is when you have been using it and you turn the system off tap etc the sediment filter the 1 you can see in starts to empty slowly to around half way then fills up when tap starts again.

dont know if that means anything

I wouldn't think being so new it could be much but i would contact your supplier & get to the bottom of it, like, tomorrow morning? otherwise you could end up going round in circles all week.

once resin tds starts to rise there isnt much you can do to stem the flow , maybe get an extra 1000 ltr or 2, but when its gone its gone.

I have tried all sorts of ways to get the resin to last longer as i have been di for nearly 3 years.

What i do is have one vessil on go until the tds rises above zero then i put fresh di vessil after the one which is rising.

So i have tapwater tds of about 80 going into vessil which is 5 approx and rising into fresh resin which comes out zero, when the first vessil gets to 80 ish i change it for fresh and put it after the last one i changed , if i have 2 vessils rising in tds together i put a third vessil in line.

Tried all sorts, nothing seams to help, i dont get stressed with it, if i start trying i am just wasting my time and time is more valuable than trying to get a few extra litres out of a bag of resin.
