Popular Anion Exchange Resin for the Removal of Tannins and Organics
Purolite© A860 is used for the removal of tannins and dissolved natural organic matter (TOC) from surface water to improve color and taste. 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. Accordingly, removal of organics which can serve as precurssors to the formation of disinfection by-products upon chlorination is also a popular application for A860. It has high fouling resistance, and is an excellent choice for most surface water treatment applications where general tannin and organics removal is the main objective.
Purolite A860 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. Purolite A860 demonstrates excellent reversible elution of organic matter upon regeneration with brine.
Field results show that Purolite A860 can typically reduce 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.
