TA213D ANION EXCHANGE RESIN is a type I macroporous strong base anion exchange resin with an acrylic matrix. The acrylic matrix ensures excellent removal of organic matter such as humic and fulvic acids from surface and waste water supplies.
TA213D ANION EXCHANGE RESIN demonstrates excellent reversible elution of organic matter upon regeneration with brine. Reduction of organic matter or total organic carbon (TOC) is an important method of controlling disinfection byproducts that can form if oxidizing agents such as chlorine or ozone are used to disinfect the water.
Field results show that TA213D ANION EXCHANGE RESIN can typically reduce influent TOC concentrations by 50 – 80%, depending on the nature of the organic matter present. For design purposes, it is best to determine TOC removal capacity from properly run field pilots. Typical capacities can vary from 5 – 20 grams of TOC per liter of resin and higher. Macroporous styrenic strong base anion resins such as TA201D can sometimes be used to supplement performance, especially in cases where removal of particularly low molecular weight TOC compounds is needed.
