Do you guys have your RO in the van or out, for those who have it in the van, How long does it take to fill up ?

Do you fill up through the RO or Ro it as you use it ?

There seems to be a lot of conflicting ideas

[geefree]

Hi Dave,

mine is 300 gpd ro-man.... in the van. connect to hose after work... it takes 5 hours to fill a 250 litre tank.....

or it did until i got all this ro trouble , now its ten hours. :

any more ?

[pjulk]

My RO it out of the van.

Can't have in the van as my hose would need to go across a footpath to get to the van.

How long does it take to fill your van with your transfer hose ?

[Roy Harding]

I have a 40x40 R/O on the van 1000ltrs in 3 1/2hrs.

Roy

[pjulk]

About 5 minutes to pump 400ltrs to my van.


Paul

[Moderator David@stives]

What do you guys do if you need to use the van while filling up.

Paul

5 mins not bad what pump do you use

[Village Gleam]

300gpd boosted 1000ibc eight mins transfer to 400l on board tank.

DI is off the van. I got that idea off you Dave, but i had to do it to go hot. You realise i was joking on the headhunt post.

I have to refill halfway through the day.

[chris@c.m.s]

I have a pumped 40x40 in the kitchen and I connect it to a hose reel run it downstairs connect to the van then it goes through the Di and into the tank. 650ltrs in about 2 hours

We are currently using 1500- 2000 litres of water a day di only.

one is a pro system, one home built.

Just looking for ways to produce my water cheaper.

Heres what i want to do i think.

Keep all filter systems out of the van. run a hose 100ft up my garden to a booster pump, then through an RO (maybe a 40/40)

then through di into 4 1000 litre ibc tanks (so i only have to worry about having enough water once or twice a week)

Then transfer to the van with a 0 tds.

Can anyone see anything wrong with this way of working ?

Do i have to consider any pre filters before the RO , dont think i need a softener my tds is between 70 - 90 in the winter.

Dave

[pjulk]

Hose that goes to your booster pump freezing in the winter

[brightnclean]

Hi Dave.

In priciple that will work fine.

A couple ofthings to consider for you. You get waste water from any RO. 1 x 4040 should be run at 50% waste minimum .. no matter what anyone says. In fact the text books recommend 15% product and the rest going to waste. SPEED OF PRODUCTION.. you are used to blasing it through DI's .. I think you will be pretty shocked at how much slower even a 4040 will produce and also unless you are on VERY GOOD water pressure you will want a decent booster pump. Around £200 for one of these and there is the running costs of it to consider  They run off mains electric. They are also noisy in operation so may cause a prob with neighbours. Also you will probably need to set up an auto cut of mechanism for when tanks are full. This does involve quitea bit of know how especially with a mains operated booster pump.

The other filters you will need will be a 5 micron sediment one firsat then a carbon one before your RO. No need for a softener as your water is decent anyway.

I estimate the cost of such a set up at around £1000.00  and that's doing it DIY.

Other than that pretty simple really  

[Village Gleam]

That's how I do it.(one IBC tank).
The transfer hose is only 30m long.
I put a canvass over the booster to bafflle the noise.
Have you though about going hot at the same time?
It's pleasanter for your employees to work with and even unskilled operators do a good job.

We dont suffer wth frost, so ok there, also i am considering 4000 litres holding tanks so at least i will have enough water on the go to see me through a day of frozen pipe.

Booster pump will be 30 metres from the nearest house so ok there,

Beginning to think it is much less hassle staying DI only, a lot less to go wrong

I reckon i spend at least £80 a month on resin, more like double ? I will have to check my reciepts.

What would you do if you had my tds

Dave

[brightnclean]

Stay just as you are Dave. Far less hassle ond basically water on demand. Swap ya for my water at 420 ish TDS?  lol 
Oh and if u have to check ur receipts to se what u spend on resin it really cant be that much of a concern for now can it?

What about running twin DI's dave & using dowex resin? cut your resin costs in half.

Tony

[Moderator David@stives]

Well

I am still getting the ibcs and a transfer pump so will take it from there , at the moment it takes about an hour to fill one 650
litre tank from the tap through the di, if i fill into ibcs in the garage say 400 litres at a time, i can leave the tap on for 5 hours.

Then just fill the vans 5 mins at a time, it gets boring running up the garden every ten minutes to see if the van is full yet.

Also when the lads run out of water, they have to come back tofill up and wait at least half an hour whilst they get an extra half a tank,
so i will save a lot of time and money just getting the ibcs and transfer pump and hose.

I already run twin DI's, I am yet to see if dowex lasts any longer.

I have never noticed any difference , Is there any proof ?

I know the colour change resin doesnt last long so ditched that filter system a cople of months back,

Dave
