1 Cubic Foot Nitrate Selective Anion Resin

1 Cubic Foot Aldex Nitrate Selective Anion Resin (NSR) with Free Shipping!

• Tested and certified by WQA in according to NSF/ANSI/CAN 61 and NSF/ANSI 44.
• Aldex NSR is a macroporous, strong base anion which is highly selective for nitrates over sulfates.
• Aldex NSR's unique functional group eliminates nitrate dumping at the end of the run even in the presence of high sulfates.
• Its resistance to nitrate dumping makes Aldex NSR a superior resin  in nitrate removal applications. 

Applications:

Aldex NSR is often selected when chromatographic dumping of nitrates must be avoided at all cost. Due to its unique functional group Aldex NSR will provide the highest operating capacity possible of any selective resin. Further, water processed using Aldex NSR will be able to meet EC as well as North American guidelines for potable water.
