Advantage, the boiler could be operated on high cycle of concentration
Disadvantage: as the RO permeate is of low pH , there might be a high risk of corrosion in the feed tank and piping if pH & Alkalinity is not maintained by proper chemical dosing

ElectroLIFE ballances the difference between the 2, descaling raw water while sanitizing and balancing the ions. Reducing scale with a balanced and re structured solution to a redoux pKw. Stricture free with 6.45 ionic product. ElectroLIFE the most advanced water utility treatment

I agree with Khuram and will add: softeners have a lower initial capital cost versus RO, which should be compared to the energy/water/chemical savings of operating the boiler at higher cycles with an RO. RO's membranes will need to be cleaned and/or have antiscalent fed to prevent fouling depending on makeup water quality. Softeners will need a brine tank with salt added regularly unless a vessel exchange program is used, some plants don't want to deal with the salt/brine tank. Lastly, if the boiler is operating at a high pressure, an RO is generally used/required due to the need for higher purity makeup water.
