as i keep gather info on building a wfp systems , ive now been informed i live in a area were the water is hard , it seems i would need a d/i systtems and a r/o systems how much can i expect to pay for a quality filtering system
-
It all depends on what your needs are for pure water.
How much per day.. do you want to be able to top-up as you go etc.
If you can give us a bit more info then we can try and help.
Cheers

i have a 50 Gall per day from RO MAN
i use 100 - 150 L's a day, just doing upstairs with WFP
per day i work, the RO is on for the 24 hours --- thus i work 3 days, the RO is on from monday night till thursday night
i let mine run into a 210 L rain water Butt (picture on front page of DIY WFP site)
i start the week with 10 X 25L barrels Full and the 210 rainwater butt full
it works a treat and is cheap enough to replace, ive had mine near 2 years now

Same as Matt mines 10 years old.

expect to use 2 litres for every £1 you earn, so if you plan to earn £200 a day you need to produce 400ltrs per 24hrs - in my experience its always better to have far more than you need, I'd always recommend a merlin, production of anywhereup to 3000ltrs per day (somtimes more) and very simple and cost efficient to maintain (sed/carbon filter every 3 months and a backflush). The merlin normally retails at £329.
You'll find a lot of the guys (and girls) on here use the merlin so it may be worth asking some of them for their opinion.

a 50 Gall per day unit is about 75 quid

if you need more water than a 210 L rain water butt and 10 X 25L barrels made up
then just spend a extra 25 quid on a extra rain water butt, thus 670 L's of water when you start your week :)

as i am looking at building my own full system which i would fit a 400 ltrs baffled tank directly into to my van, connecting system via water tap so baffled tank can be filled overnight , as i quoted in my earlier message the area i live in is a hard water area
so ive been informed i would require a R/O and D/I filtering unit so that i can bring water reading down to zero
any help would be appriecated

If you want to fill a 400 ltr tank overnight I would suggest either a 300 GPD RO unit such as an Ro-Man one or as suggested by JM 123 a Merlin. The 300 GPD should fill it overnight if you have average water pressure and get your TDS down by 95 to 99% Then you just need a small to medium DI polishing vessel to get it down to zero.
The Merlin is great if you have good water pressure and will produce water a lot faster than the 300 gpd unit but it probably wont be as efficient at getting the TDS down. You would probably use a bit more resin with the merlin but the trade-off is the fast water production.
Dont be tempted to go for anything less to save a few quid. a 200 GPD unit MIGHT.. but only might fill up the tank overnight.
Just a suggestion.. have you thought about producing your water into a static tank such as a 2nd hand 100 ltr IBC then transferring it over using a submersible pump? It does have its advantages one of the main ones being that your van isnt tied up all night whilst filling your tank.
Hope this helps
