Boiler feed water hardness must be 0 °fH; conductivity, silica and oxygen are limited according to boiler pressure (TS EN 12953-10, ASME). Softening is the mandatory minimum, while RO is the preferred stage that lowers the blowdown rate and fuel consumption. Oxygen scavenger and alkali dosing are part of chemical conditioning.
