AnoxKaldnes ANITA™ Mox For efficient ammonia removal

“More than 90% of ammonia and 75-85% of total nitrogen can be removed” An energy-efficient process for removal of high ammonia loads in wastewater The ANITA™ Mox processes – MBBR (Moving Bed Biofilm Reactor) and HYBAS™ (Integrated Fixed Film Activated Sludge) are single-stage deammonification technologies where more than 90% of ammonia and 75-85% of total nitrogen can be removed. The processes accomplish this removal without the addition of an external carbon source and with considerably less energy in comparison to conventional nitrification - denitrification. The ANITA™ Mox process is specially...

Reject water treatment High ammonia concentration with low COD concentration are typical characteristics of the reject water coming from dewatering of the digested sludge. Usually sent back to the main wastewater flow, the treatment of this ammonia load through conventional nitrification/ denitrification can be quite cost-intensive. The use of the ANITA™ Mox process on reject water is a way to treat a part of the nitrogen at a low energy and chemical cost and thus reducing the overall consumption. In addition, it can dramatically reduce the nitrogen load on the main biological treatment line...

The HYBAS™ advantages Flocs (1-3 g/L) HYBAS™, IFAS (Integrated Fixed Film Activated Sludge) Nitration technology using suspended AOB carriers has been a proven  application of the MBBR more than 20 years. NH4 + process NOfor 2 N2 Applying the same concept to ANITA™ Mox has shown Liquid O2 significant benefits. As with any HYBAS™ system, suspended growth is retained in the system using a separation unit such as a settler. Anammox With HYBAS™ ANITA™ Mox the nitritation step, or the conversion from ammonia to nitrite, takes place in this Anoxic Biofilm Media The production of nitrite has shown...
