Ammonia

Ammonia can be removed from drinking water and wastewater sources via two primary methods, oxidation through the breakpoint reaction or biologically.

With a complete lineup of solutions, De Nora can help you choose the right one for your specific application based on your process and water quality.

 

OXIDATION METHOD

The oxidation methods remove ammonia by the breakpoint reaction, whereby the ammonia is oxidized to nitrogen gas, most often using chlorine.  Most commonly used for lower levels of ammonia (<5 mg/l) or drinking water systems, it has the advantage of being simple and effective.  De Nora has multiple options available to best suit your needs.  From chlorine gas to generating your own hypochlorite on-site, we can provide you the best combination of whole-life-cost, safety and effectiveness for your plant.

 

BIOLOGICAL METHOD

The biological method uses facultative bacteria, supported on a media bed, to remove the ammonia.  Most commonly used for higher levels of ammonia and industrial and municipal wastewater systems.  Chemical-free, it is quite cost effective and simple to operate.DE NORA TETRA (R) SAF and COLOX filters are nitrifying filters used biologically oxidize ammonia-nitrogen for effective

wastewater treatment.  Combing De Nora proprietary Snap-T(R) block underdrain with years of biological filtration experience allows De Nora to provide the best technology in the most cost-effective way to reduce ammonia loads in wastewater effluent.
