Floating Bed Softening VS Fixed Bed Softening in Performance

Comparison

The ion exchange equipment, because of its function, corresponds to the process in the following three main applications:

The extraction of the required chemical substances.
Replacement of ions in the water, allowing the water to be purified.
Removal of calcium, magnesium and other scaling metal ions from the water.

Here we focus on the purification of water and the removal of calcium and magnesium ions. Ion exchange occupies a very important position in the water treatment industry and with the passage of time and familiarity with the process itself, the ion exchange process has given rise to more and more sub-processes in the equipment.

By regeneration of the ion exchange. There are downflow regeneration and upflow regeneration.
By the movement of the ion equipment. It can be divided into fixed bed and floating.
