Across Australia and in other parts of the world, nitrogen removal has become an essential process of wastewater treatment. The conventional method of nitrogen removal - the nitrification and denitrification pathway requires substantial oxygen transfer (approximately 4.3 g of O2 for each g of ammonia-N) and carbon (about 4 g/g of NO3–N reduced). In the case of low carbon, high nitrogen wastewater, the addition of an external carbon source is required during the denitrification stage to effectively convert nitrate to nitrogen gas. These escalate the cost of the conventional nitrogen removal process, and utilities and industry have been looking for alternative low-cost nitrogen removal technologies. Some of the recent innovations in nitrogen removal include the anammox process, and struvite precipitation (precipitation of ammonium and phosphate as MgNH4-PO4, with the addition of magnesium salt if needed).
This presentation discusses the retrofitting of the anaerobic ammonia oxidation process (anammox) by Environmental Engineers International Pty Ltd (EEI) to an existing abattoir wastewater treatment plant (WWTP) in Western Australia. Abattoir wastewater requires advanced treatment prior to discharge to the environment due to its high nitrogen content. Since the implementation of the EEI-Anammox process over the past two years, the WWTP has consistently achieved good nitrogen removal, without any extra carbon addition. The plant is monitored online for various parameters to ensure its effective operation. The WWTP has achieved over 20% savings in overall electrical power since the implementation of the anammox process. Unlike the European case studies, the WWTP has achieved over 95% TN reduction even during the winter months when the temperature has fallen below 15oC.
