WATER

An indispensable product for the treatment of water.

Caustic soda is widely used in the treatment of water. In sewage treatment stations, caustic soda allows the neutralisation of effluent and a reduction in the hardness of water. In industry, caustic soda allows the regeneration of ion exchange resins.

Caustic soda is a very strong base, having relatively high solubility in water. Thanks tocausti soda’s liquid from, measurement of the amount to be used is greatly simplified in a large number of aplications in the water treatment field.

Caustic soda is currently used treatment with various objectives:

• elimination of the hardness of the water;

• regulation of the water’s pH;

• neutralisation of effluent before the water is discharged;

• regeneration of ion exchange resins;

• elimination of heavy metal ions by precipitation.
