Right I have decided it's time to bring WFP into my round and would appreciate some advice regarding setup.

After doing a bit of research I think a trolley system would be the best for me at the moment with a view to switching to a van mount when the time is right.  I currently have around 160 properties (been going around 9 months now) which some would defo be more suited to WFP.

So WFP...I really need some advice as to how to get setup.  Again from research I believe I would need a trolley and a DI vessel to make the water.  So am I right in saying the water comes from the mains, passes through a DI vessel which contains resin to purify the water, and straight into 25l-50l barrels (if using a trolley) or straight into a tank if using a van mount?  The water is then pumped up the pole and so I would need a pump, a battery, and a digital flow controller. 

As you can see I am a novice with WFP and could really do with a bit of advice. 

DAZMOND  - hopefully you will read this post as I know you have recently switched over to a trolley system and are chuffed to bits.  Good on you.  If you have any advice for me I'd really appreciate your help with getting setup.

Cheers, Mike

I would go straight to van mount, I had trolley for a year........
Hindsight is a great thing........

first off mike get yourself a tds meter and check the tds of your water.if its over 100tds then i think you d be better getting a RO UNIT.

if its between 35-80tds out of your tap i would get 2 DI VESSELS(11L)and have them goin in tandem.yes you are correct just tap/di/barrel!very simple and easy!!

i have 12 barrels in van (300L)and just hook up hose/di and hey presto!pure water!takes about 50mins to fill up.

i have the 50L TROLLEY from pure freedom and im so glad i didnt get the 25L version as im changing barrels less often.i also have 30m of extension hose so im not moving the trolley as much and i leave it in the van and it doubles as a mini van mount for some stand alone accounts

the trolley is ideal for a lot of my work as its very compact with parking issues.the trolley is a fantastic piece of kit.if your work is very scattered and big jobs with easy access i would say go straight to van mount.

hope this helps.i better get off here my missus wants me to take her to ikea!! : :

do it properly the first time, 250-400l tank for 1 operator mounted in the van

[darren clarke]

what van u got


go van mounted dont bother with a trolly

[Mike55]

Ford Escort 55D van.  I think the payloads on these are about 475kg.

One other thing, I live in a 300 ppm area but have been told I only need DI system due to the size of my round.  Am I correct in saying that RO is suited to bigger rounds only?

[darren clarke]

no the ro is for the tds of your water  u need  a ro and tank,  i would run with 250 tank in you escort and a flow control

who told you ro is only for big rounds

[andyM]

Yes you will need an RO Mike.
300ppm water will cost you a fortune in resin, the Ro will work out much cheaper in the long run.

[Mike55]

I spoke to someone from Aquafactors (formerly tuckerpoles I believe) who said I would only need DI resin system.  I must admit I thougt that DI was a polishing resin and not designed to purify hard water (from my limited research).

He suggested that the savings made from an RO system would be minimal compared to a DI system and wasn't really worth getting an RO.

[darren clarke]

doesnt know what he is talking about

[andyM]

He may or may not of had his reasons for saying that.  
Resin alone will reduce 300ppm water to 0ppm but at a guess from an 11ltr Di Vessel you will probably only produce about 1500 to 2000 ltrs of water before it will need changing.
And at about £40 per 11ltr resin change, do the maths.
I guarantee you although an RO will be more expensive to purchase initially, in the long run with the water of 300ppm you have it will be the cheapest option.
No bull, just honest advice.
 

[Mike55]

Is it worh using a DI vessel first and switching to RO once my round becomes bigger?

That way I get an intro to WFP without having the spend too much.  I won't need to use a great deal of water initially as I don't have a full round.

[andyM]

Yes you can do it that way if you wish. The di vessel can still be used to polish water to 0ppm if you later decide to produce more water and buy an RO.

[Mike55]

Might be the easiest way to get 'up and running' as it were.

My understanding is that it will cost about £80 a month in resin if DI only.

What is the running costs if using RO?

[Mike55]

£80 a month based on a full round that is...

[andyM]

If you change the pre-filters every 6 months cost about £15
Ro membranes should last a couple of years cost around £30-£40 per membrane, bigger 4040 Ro's are much more expensive though.
If you are on a water meter it can be quite expensive as an RO can produce around 50% to 75% waste water, depending how efficient it is.

[darren clarke]

is it higher your tds is the more waste u make?

ie 300 tds = 50% waste

100 tds 25% waste?

[robbo333]

I've just started so it's new to me too. I'm in Essex and my ppm is huge. I bought a system from pure freedom and I have to say they are pretty good. I have had a few problems with it but they have done their best to solve them. To get my tds to 0, I just bought an extra di unit for 30 sqid..ish which took it from from 16 ppm to 0. I am a happy boy.

Hi Pete. What sort of system did you get and are you ro or di setup?
