Softening Systems

The hardness of water is measured as the concentration of dissolved mineral salts of calcium and magnesium and can also be categorized as temporary (carbonate hardness) and permanent (non-carbonate hardness).

Water softening systems are used to separate the Calcium (Ca+) and Magnesium (Mg+) ions that cause hardness from the water. Thus, the water is softened. During this process, minerals that pass through the resin bed and cause chalky water gradually cover the resin. The water softening process continues until the surface areas of the resin grains are completely covered with hard water minerals. However, when the resins are completely covered, the programmed auto-adjusted automation valves are activated and the resin bed is rinsed with the solution (sodium chloride) and refilled with sodium ions. The hardness ions previously removed are washed away to be discharged during the regeneration process.

  • Choosing the right tank according to the amount of resin to be used,

  • Determining the amount of resin to be used,

  • Calculation of the highest (peak) flow and nominal flow according to the hardness value of the water,

  • Appropriate selection of the speed of the water passing through the tank,

  • More importantly, the conditions that adversely affect the softening of the water must be eliminated before the softening process.

     Soft Water Usage Areas

  • food industry

  • Use as a pretreatment system before reverse osmosis  (Reverse Osmosis)

  • chemical industry

  • pharmaceutical industry

  • Surface water treatment

  • groundwater treatment

  • Clean water supply

  • Pre-treatment system before boiler feed water

  • Nice process for softening water

Deionization Systems

Deionization systems are systems to meet the high quality pure water needs of industries such as cosmetics, glass industry, pharmaceutical industry, textile and energy sector. 

Deionization (DI) is a water filtration process in which total dissolved solids (TDS) are removed from water through ion exchange. The deionization process uses two resins opposite in charges - cationic (negative) and anionic (positive). Cationic resin is typically made of styrene containing negatively charged sulfonic acid groups and is pre-charged with hydrogen ions. This resin will attract positively charged ions (Ca++, Mg++, Na+, etc.) in the water and release an equivalent amount of hydrogen (H+) ions.


In some conditions  cations and anions can be removed in the same unit.  This type of unit is called mixed bed ion exchanger (Mix-Bed.Bed. In this unit, water is first passed through the cationic resin and the positively charged ions are passed through the hydrogen ions, and then through the anionic resin, the negatively charged ions are replaced with hydroxide ions. Thus, highly pure water is obtained. When the resins reach saturation as a result of use, the system  is regenerated. Thanks to the regeneration process, the resins regain the decreased efficiency. Deionization process varies depending on many factors such as water quality and economy, ion exchange type and regeneration method.
