hi all
i'am new to window cleaning and wfp,i hav a di system my tds input is 530 the resin only lasted 3 days!
i no from this fourm that i need an ro system,
i live in a flat so a static system will be hard for me to do,
i carry a 500L tank in my van and at the mo i pump from there into my two resin tubes then to my pole,
i use about 400L of water a day
so what ro system would i need and were from?
also how much waste will i produce as i use a 100psi pump?
cheers for any replys

HI

You would probably be best getting a Merlin RO system, this will fill your tank pritty fast.

You will probably also waste 2 litres to make one litre

is there not a sytem that i can pump from the tank to the ro and di then on to my poles

[REVIVE-A-DRIVE]

my reason being is that i also use the same tank for pressure washing and i didn't want to waste the pure water doing the pressure washing.

do some research on how reverse osmosis works on the net and you will be more able to make an informed desision, it will help you understand why it is best to fill your tank with water from an ro(reverse osmosis) rather than use an ro on the go. one point is that your 500l tank full of tap water will probably only give you 160litres of pure water.

good point,so how long doe's it take the merlin to fill 400L?
i no it depends the psi from the tap, mine is pretty good from tap.

this is a guess from what ive read but i think about 4 or 5 hours to fill 400l but matbe im wrong. easyclean has got a merlin hes the guy to ask. There are some prevous post about merlins. merlins are very fast but at the expense of tds i think they take the tds down by about 90-95% where as other ro's take it down by about 98% or maybe better. you have to research this it is a must, dont rush because you are going to need to spend £300-£600 depending on what you decide so you better make sure you choose carefully. Hope this helps
Oh did i mention research

[matt]

you really should get a RO, otherwise you will be spending all your money on resin

My Pentek R/O will produce 1000ltrs in 3hours at 80psi thats 5ltrs a minute.

My tap water tds 234 but after R/O is 0.02.

You are talking £550 - £600 for the R/O pluss 20" fillters ect.
