Caustic soda softening is typically used when the treated water has inadequate carbonate hardness to react with lime. Softening by lime and lime-soda ash is generally less expensive then by caustic soda. However, caustic softening produces less sludge and unlike lime does not deteriorate during storage. Figure 1 shows lime-soda softening.

Lime-Soda Ash Softening - mrwa

Lime is used to remove chemicals that cause carbonate hardness. Soda ash is used to remove chemicals that cause non-carbonate hardness. When lime and soda ash are added, hardness-causing minerals form nearly insoluble precipitates. Calcium hardness is precipitated as calcium carbonate (CaCO 3). Magnesium hardness is
