Boiler feed-water treatment: hardness, TDS and pretreatment

Boiler systems can be sensitive to scaling and corrosion, so feed-water treatment should be selected from boiler pressure, makeup water and operating targets.

Boiler feed-water treatment: hardness, TDS and pretreatment
In this guide

This article explains the treatment objective, the design information that matters and the operating checks that help keep the system practical after installation.

Hardness can create scale

Calcium and magnesium can concentrate as water is heated and evaporated. Softening or more advanced treatment may be used depending on the boiler and feed chemistry.

Dissolved solids accumulate

Boiler operation concentrates dissolved material, which is why blowdown and feed-water quality are linked. Conductivity is often used as an operating indicator.

Follow equipment requirements

The boiler manufacturer or water-treatment specialist should define acceptable feed-water limits and chemical-treatment needs for the specific system.
