| Hi B Scott,
Yes you are right. Demineraliser incooporate cationic and anionic resin, housed in two different tanks. Regeneration process is actually quite simple, using HCl and NaOH. Piping is installed in such a way that make backwash and discharge flow direcrly to the drain.
Of course, all in all, RO is simpler and better. But as I said, my water supply is prohibitive. so I have to look at other alternative. |
