Nitrogen Removal Publications
Removal of Nitrate by ‘Anoxic Absorbent Filtration’ and Carbon Addition
Published in Influents, 2009
Performance results of the WaterNOx, a biological anoxic filter for enhanced nutrient removal, are detailed from two separate field test sites.
Nitrogen Removal with the Waterloo Biofilter
An open letter to water and wastewater engineers details the biochemical processes involved in nitrogen removal, and provides supporting documentation from third party testing showing the nitrogen removal capabilities of the Waterloo Biofilter system.
Predicting Nitrification Efficiency from Dissimilar Wastewaters
Presented at WEAO Conference, 2004
An underperforming aeration treatment plant is retrofitted with a Waterloo Biofilter as a polisher to meet ammonium levels for surface discharge. Operational data from two dissimilar wastewaters is used to successfully predict performance on a third wastewater.
Agricultural Mineral Soil Additives for Passive Nitrate Removal
Presented at NOWRA, 2017
Removal of nitrogen (N) from individual sewage systems is desirable where residences are near saline estuarine water bodies, or on groundwater aquifers.
