Hi peeps , as it was raining all day i had one of my nutty proffeser days , i was sat mulling over old posts and it hit me , i remember reading a reply about spotting , that if you cut the flow back the water would spend more time in contact with the resin , thus being purer .
I went out and bought a 10L plastic bin and 2 elbow connectors for the princely sum of £8 , i then cut them into the bin , entry on bottem of one side and exit at top of other side , i then put my old resin from 2 DI fills into bin , oh and i zip tied a piece of fine cloth to each of the elbows on th inside to act as filters.
Then i connected to tap and turned on to very low flow , the tap water was going in at 104 TDS and was coming out at 000 .
Admitedly it was a slow process , i was getting 25L per hour .
The TDS has not yet risen after 50L , thats all the storage i had as the van tank is full , but if i left it on all night at that rate into a butt it would fill it.
I will let you know how many litres it goes for , here are some pics ...
