I did a quick google search yesterday for "ammonia sorbent" and "ammonia filter media" and saw a couple of products, including a natural zeolite. I could see using this ahead of the system to scavenge free ammonia. I assume the leaching would be less of a problem than if I...

Thanks for the reply. I have considered amine throw from the anion resin, but we have tried both "seasoned" resin and virgin highly regenerated resin (cartridge type) as a polisher. The final water ranges up to 1.0 mg/l of ammonia. I think I possibly have a more fundamental problem. If...

My customer, a small municipal water treatment plant laboratory, is detecting ammonia in their BOD test reagent water following a treatment system that includes carbon, RO, DI & UF. We recently switched to calalytic GAC because of different chemistry with monchloramine (the source is right at...

I have had success with Chloride form Anion resin installed in a small 1-2 cu. ft. exchange tank. In natural waters (pH7-10) the soluble caronate complexes of UO2(-2) are predominant anion species UO2(CO3)2(-2) and UO2(CO3)3 (-4). Monitor for Sulfate breakthrough as an indicator to pre-warn of...
