It depends on the cost of chemicals for regen vs the cost of electricity. If your EDR product is greater than 100 ppm TDS, I think it is worth looking at an RO to reduce the conductivity further. If your EDR product is below 100 ppm, an RO probably won’t be economical.

Correct, the chemical costs determine the cutoff point between ion exchange (IX) and RO. We normally recommend RO above 500 ppm, but it also depends on scaling and fouling issues. IX is generally more robust with challenging waters.
