Biologically induced phosphorus precipitation in aerobic granular sludge process [PDF]
, 2011 Aerobic granular sludge is a promising process for nutrient removal in wastewater treatment. In this work, for the first time, biologically induced precipitation of phosphorus as hydroxyl-apatite (Ca5(PO4)3(OH)) in the core of granules is demonstrated by

Simulation of dissolved nutrient export from the Dongjiang river basin with a grid-based NEWS model
E3S Web of Conferences, 2018 In this research, a grid-based NEWS model was proposed through coupling the geographic information system (GIS) with the Global NEWS model framework. The model was then applied to the Dongjiang River basin to simulate the dissolved nutrient export from ...
