View attachment 6727 Just took a look at the system my friend uses in his factory (where I fill up)...TDS is around 470 here, the 7 is post RO and comes out around 0 after going through that big DI cylinder on the right. Makes about 500L per hour...I've never made pure myself so don't know too much about it, this system looks pretty good though.
