The Experimental Research on Performance of the Composite Ion-Exchange Regenerant FH-30

Abstract

The composite ion-exchange regenerant FH-30 was made using the own patent technology. The effect of softened water quality and running cycle, after the use of FH-30, was studied under simulation of industrial boiler softened water preparation process conditions. The dynamic simulation experimental results showed that at room temperature, the flow speed of 35 cm/min, the running cycle would not change when the dosage of regenerant was changed, the sodium and ammonium ion content would decrease with the increase of the running time in the softened water preparation process, the sodium ion content would decrease a bit faster at the later running cycle when the dosage of regenerant was greater, the molar ratio of sodium and ammonium almost not changed in the softened water preparation process when the regenerant dosage was 2.1 gram per milliliter resin, composite regenerant can completely replace single sodium salt regenerant. Through the measurement of sodium and ammonium ion in the regeneration resin and failure resin, proved that sodium and ammonium ion were not accumulated in the resin layer.
