Ion Exchange Water Softener For RO Water Plant Equipment Softened Water
Softened water equipment
The ion exchange method can remove the cations and anions in the water state, and the sodium chloride
(NaCl) represents the inorganic salts in the water. The basic reaction of water and salt removal can be
expressed by the following equation:
Cation exchange column (sun bed): R-H+Na+→R-Na-H+
Anion exchange column (anion): R-OH+Cl--→R-Cl+OH-_
After the cation and anion exchange columns are connected in series, they are called complex beds. The
total reaction can be written as:
RH+ROH+NaCl-------RNa+RCl+H2O
It can be seen that the NaCl in the water has been replaced by H+ and OH_ on the resin, respectively, so
that the effect of removing salt in water is achieved.
Mixed ion exchange column (mixed bed): The mixed bed is made by mixing the anode and the anion resin
into a mixed column at a certain ratio (1:2, so that the anode and the anion resin simultaneously reach the
exchange end point). H+ and OH_ in the water immediately form water molecules (H2O) with little
ionization, and there is almost no reverse exchange phenomenon in which the bed or the negative bed
exchange occurs, so the exchange reaction can be carried out very thoroughly, thus the mixed bed The
effluent water quality is superior to the water quality that can be achieved by the double bed composed of
the cation and the yin bed, and the finished product water with a relatively high purity can be obtained.
