please could someone advise me on a ideal wfp setup on a 250l tank van mounted system.
what type of r/o & di etc
thanks.
Hi
as for ro and di depends on your water quality and how quickly you need to make it, if you only going to need 250 ltrs a day and have space for a holding tank to transfer water to your van then a cheaper ro that produces slowly but can be left on while out working will be sufficient.
When I had a 250 tank I used a merlin as it would produce fast but with higher tds = more resin but I do not have the space to store vast amounts of pure water, hence I now have a 4040 ro much more efficient for my needs but initially more expensive. Also depends really if you are on a meter or not.
Post a bit more info and I'm sure others can help you make the right descision.

* oh and btw I'd suggest getting a 250 upright tank as when you get low on water its easier to keep working else unless you park on hills/kerbs chances are you'll suck air, a varistream or similar will also help you make the water last longer especially on repeat regular cleans where you can use a lower flow rate
