Removes dissolved solids from the steam drum to manage TDS.
Minerals like calcium and magnesium precipitate out of hard water, forming insulating scale on heat transfer surfaces, reducing efficiency, and causing overheating. practical boiler water treatment handbook pdf
Calcium and magnesium salts precipitate out of the water, forming a hard, insulating layer on heat transfer surfaces. This significantly reduces efficiency, forcing the boiler to work harder, and causes localized overheating leading to tube failures. Removes dissolved solids from the steam drum to manage TDS

Before water enters the boiler (as "feedwater"), it must undergo external treatment to remove bulk impurities: Removing suspended solids and organic matter.
