Boiler water treatment - Lenntech

In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the boiler system in question. There are many types of external treatment ( softening, evaporation, deaeration, membrane contractors etc.) which can be used to tailor make feed-water for a particular system.
