Water Softening using Ion Exchange Resins
High concentrates of calcium and magnesium carbonates in water increases its total hardness, which leads to scale formations and deposits.
Strong Acid Cation (SAC) is used to exchange Calcium & Magnesium with Sodium, where the total hardness of the water is decreased.
The resin should have uniform characteristics, providing
- High exchange flow rates during regeneration and loading
- Good utilisation of the total capacity
- Low rinse water demand
- Homogeneous throughput of regenerants, water and solutions; therefore a homogeneous working zone
Benefits using ion exchange resins for water softening are;
- Removes dissolved inorganics effectively
- Regenerable (service deionisation)
- Relatively low cost initial capital investment
- Long life of resins, leading to low cost maintenance & operation with system durability.
- Almost totally automated systems.
