Demineralized water treatment plant working process:1.Two-bed IX

Two-bed or dual-bed exchangers treat a stream with two or more IX resin beds or columns, each carrying a different type of IX resin. A stream is initially treated with a strong acid cation (SAC) resin, which collects dissolved cations and releases hydrogen (H+) ions in exchange in two-bed demineralization.

The mineral acid solution is subsequently sent to the resin bed for strong base anion (SBA). The anionic pollutants are sequestered in this second stage, which also releases hydroxide (OH–) ions, which combine with the hydrogen ions (H+) to produce water.

The resulting stream has a pH of almost neutral and is low in TDS.While two-bed exchangers are successful at demineralization, salt leakage can degrade the output quality, particularly in streams with high TDS and/or low pH.

2. Mixed-bed IX

When compared to twin-bed systems, mixed-bed exchangers provide better water quality. Mixed-bed ion exchangers contain a variety of IX resins within a single IX column. When a stream is fed to the unit, the cation and anion exchange reactions occur simultaneously within the unit, solving salt leakage difficulties that can degrade the water quality generated by a twin-bed IX system.

While mixed-bed exchangers produce better water, they also necessitate a more time-consuming resin renewal procedure. Mixed-bed units are also more sensitive to resin fouling ands poor system performance due to changes in stream contents, hence they’re usually utilized after other treatment methods.
