The problem can be avoided by removing the salt content of the makeup water in a reverse osmosis plant or in a two-column ion exchange plant to get demineralized water. To sustain high purity feed water and makeup water, an optimum boiler water treatment system therefore primarily consists of pressure filter, softening plant, reverse osmosis

2016-11-1·The feed water to the boiler has to be treated to protect against scaling and produce high quality steam. Scale is precipitated impurities out of the water and then forms on heat transfer surfaces. This is a problem because scale does not transfer heat very well and causes the boiler tubes to fail by getting too hot. This will reduce the boiler

BOILER WATER TREATMENT - water-chemicals.c

Different treatments are used to avoid scaling, corrosion, and/or foaming. While external treatment of feed water deals with removal of impurities prior to boilers, internal treatment of the boilers deal with the tendency of water to dissolve, maintaining troublesome impurities before they can be removed from the boiler in boiler blowdown.
