Simultaneous partial Nirtification, Anaerobic ammonium oxidation(anammox) and Denitrification, SNAD, a sustainable result

The novel anaerobic ammonium oxidation (ANAMMOX) is based on energy conversion by using ammonium over nitrite is the recent finding for nitrogen removal. However, ammonium rich wastewater produced with a certain range of COD. A combination of ANAMMOX and denitrification would fit the requirements.

Leaderman & Associates has developed the state of the art-SNAD process provides the removal of ammonium and COD in a single reactor can be applied in different categories of wastewater.

Anammox Key advantagesI:Save capital and operation cost,Reduce footprint with a single reactor,No chemical dosage,Save energy

Anammox Key advantagesII:Less sludge production,Less greenhouse effect,Suitable for high-strength,ammoniumwastewater with low COD,Use bio carriers to increase removal efficiency

The first full-scale occurrence of SNAD process observed in a single bioreactor in leachate treatment plant in Taiwan. The treating capacity of leachate treatment plant is around 300 CMD.

The MBR system has been installed in an aeration tank in order to retain Anammox to increase the ammonium removal efficiency up to 80%.

Application in opto-electronic wastewater

Ammonium influent concentration up to 3,000 mg/L. The ammonium and total nitrogen removal efficiency close to 95% and 80%.

The SNAD process can be acclimated in leachate, a mixture of high concentration organic and inorganic contaminants.

The SNAD process can be duplicated in other wastewater treatment plants efficiently.
