ZG FS 821 Arsenic and Fluorine Removing Resin

 

ZG FS 821is a special resin with gel structure. It is a macromolecule copolymer with activate rare earth elements on its styrene-DVB matrix. This kind of chemical structure is easy for fluorine, arsenic in water to form stable complex compound, thereby to reduce fluorine and arsenic density in water, in the end reach to the National Drinking Water Standard: arsenic less than 10mcg/L, fluorine less than 1 mg/L. It could also apply to recovery arsenic and fluorine in industrial waste water.

ZG FS 821 has comparatively higher adsorbent capacity and faster adsorbent speed to fluorine and arsenic. It could reduce arsenic and fluorine in solution efficiently, and reach to the safety standard. Moreover, it could use NaOH as eluent media to wash, and then use 5-10% sulfuric acid to adjust pH range to 4-6, thus the resin could be used again to adsorb elements after regenerate.
