Water softenerSystem of water softening


Water softener the ITG Sarajevo is applied for softening of water, which is physically clear, and without mechanical impurities. It is used for softening of boiler feed water in power plants, chemical and textile industry, for cooling water, water heaters and there where softened water is required.


Water softening is done by filtering, through a water-insoluble layer of ion exchange resin, which has the ability to reversibly exchange its ions with inorganic salt ions in water. Calcium and magnesium salts are removed from water, because calcium and magnesium hydro carbonate are transformed into sodium carbonate which is not deposited as a scale.


Water softeners are manufactured in standard dimensions, capacity goes from 0,5 m3/h up to 6 m3/h in 11 sizes and three designs as follows:

  • filter and salt vessel as one unit
  • S-design with a filter and salt vessel, separately
  • D-design with a two filters and salt vessel, separately

Delivery of water softener also include ion-exchange resin, internal piping, pipe fittings, water meter and mini laboratory for water quality control.

Filters are dimensioned in such a way to achieve optimum between the quantity of treated water and the time between two regeneration. Vessels are made out of steel plate and are protected with an anticorrosive coating.


Our water softeners are designed for maximum pressure up to 6 bar, and are tested on 9 bar.
