Anion exchanger AB-17-8 is normally regenerated with alkali or table salt (in the first case, it will replace all anions with OH groups, in the second - with Cl). There is no selectivity for different anions - it changes all of them. In the purification system KU 2-8 (regeneration with acid) and AB-17-8 (regeneration with alkali), after washing out the residues of regenerating solutions, you will obtain water with parameters similar to those of distillate. In any case, the quality of purification with the reverse osmosis system is higher.

The point is that we are not satisfied with the quality of purification by the reverse osmosis system, so we pass this already conditionally purified water through ion exchange resins. The TDS meter shows 10 at the output of the osmosis, and 0 after the resins.

If it's after osmosis, then it's really not worth bothering with separate ion exchangers - it's easier to buy a mixed bed resin cartridge - it should last a long time.

So it's not suitable if I understood correctly. If someone has a Mineral Salt solution without salt. And I wanted to clarify which cartridges are used in the osmosis system or in what order.

Senya, we need to test whether it removes phosphates and silicates. Mix cation resin with anion resin and fill the cartridge, but not completely, otherwise the resin will swell and may rupture it. In what sense, in what order? Are all cartridges in the reverse osmosis system? For me, it goes like this: Pre-filter > 3 cartridges with carbon (Post-filter) > Membrane > 2 cartridges with resin (Pentek). To reduce the water flow, I inserted a smaller tube, like the one from a dropper, into the tube that goes from the storage tank to the resin cartridge.

Do not mix - just add the anionite and check for silicates...
