General

WATCH AMMONIUMSORB® is an natural ion exchange mineral based on the sodium ion. WATCH AMMONIUMSORB® is very selective for ammonium in freshwater applications, the product can not be used in seawater.

How it works

WATCH AMMONIUMSORB® ions in the water enter the WATCH AMMONIUMSORB® granule and replace a sodium ions located in the adsorber lattice. The ions effective exchange places, hence the name "ion exchange" mineral. After a period of time, normally a few hours to days, the WATCH AMMONIUMSORB® will need to be regenerated. As a rule of thumb guide, 1 kg of ammosorb will remove between 1 and 5 grams of ammonium. The actual capacity of the product will depend on the concentration of other cations in the water. The softer the water the better the performance of WATCH AMMONIUMSORB® .

In order to restore the capacity of WATCH AMMONIUMSORB® , the ion exchange process in reversed. This can be achieved by passing seawater through the ammosorb media, or by using a sodium based regenerant.
