Product Details

In the hydroxide form, Strong Base Anion (SBA) resins are strongly basic enough to remove both strong acids such as hydrochloric and sulfuric acids and weak acids such as silicic and carbonic acids from the effluent of a hydrogen form strong acid cation exchanger where neutral salts are converted to corresponding acids. In other words, SBA resins remove all anionic contaminants present. As a comparison, weak base anion (WBA) resins remove only contaminants such as sulfate and chloride, which are strong acids, and will not remove contaminants such as silica and carbon dioxide. This is not necessarily a negative aspect of a WBA resin if the product water need not be free from silica and carbon dioxide. Indeed, this can be a positive aspect of weak base anion resin given that WBA resins typically have greater capacities for mineral acids and higher regeneration efficiencies than SBA resins.

Lanlang ® TA207

High capacity gel type I strong base anion resin

Is highly recommend to you, TA207 in chloride form could remove both strong and weak acid radicals such as sulfate, nitrate, arsenate, chromate and silicate to extreme low concentration level.

Odor Considerations

Anion resins have a distinct odor, especially SBA resin in the hydroxide form. High pH increases the degradation of SBA resins and, therefore, increases its odor. The degradation product responsible for the odor off of a Type I SBA resin is amine and has a strong fishy smell. The amine is cationic; therefore, it can be removed by cation resin. The degradation products of Type II SBA resins are alcohols and aldehydes and have less objectionable odors than Type I resins. SBA resins throw fewer odors in mixed beds because of lower pH. In the case of mixed beds that use Type I resin, the cation resin also removes the amine.

Temperature Limits

High temperature degrades the functional groups of all SBA resins. Type I resins are the most thermally stable followed by Type II with acrylics being the least temperature resistant. All the SBA resins are more susceptible to temperature degradation in the hydroxide form than in the chloride form.
