RO Scale Inhibitors - Reverse Osmosis TreatmentAdvanced Reverse Osmosis TechnologyRO Scale inhibitors or antiscalants can be dosed before or after the system cartridge filters. If iron is present in the feed water, the antiscalant can be dosed post to prevent “pick-up” of iron (or in the case of polymer antiscalants de-activation by iron – in this case use a phosphonate based product with good iron sequestering properties). The dose point should be after the sodium bi-sulfite injection to ensure chlorine is removed (especially with high levels of free chlorine). Dose point should be sufficiently down-stream of the SBS injection point to avoid “neat” product mixing.
