So how do you caustic flush?  I just turn the blue nob and give it a normal flush.

You want to be careful with using chemicals with cleaning your membranes. You need to have the ratios spot on or you will actually ruin your membrane.

yeh there is a way of doin this but as the lad says ratio can cause damage mate get it right. i think it is flushed through the di vessels  caustic soda and hydrocliric acid mix  but have not tried it meself.  the end result is regeneration of the resin.

I think you are getting two different processes mixed up. You can regenerate resin by immersing it in a casutic soda solution. The resin will split, about half will sink and the rest will rise to the top. You need to skim off the resin that rises and immerse it in a hydrochloric acid solution.

Once it has divided it is best to use two resin bottles, the anion in one and the cation in the other. That way you never have to split them again.
