IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Treatment of Nitrogen Polution in Aquaculture Wastewater by Addition of Carbon Source
Author : PHAM THI HOA
In this research, nitrogen in aquaculture wastewater change as respond to the addition of carbon source to the system were studied in microcosm experiments. Nitrogen transformation was studied by looking at the change in different forms of nitrogen including the total nitrogen (N), total ammonium nitrogen (TAN), nitrite and nitrate. These parameters, in high concentrations, are very likely to negatively affect pond water quality. Nitrogen from aquaculture wastewater also badly affects the receiving waterbodies and ecosystem health. Results from this study show that the addition of carbon source and aeration in pond water reduced TAN, nitrite and total N concentrations. It proved that this simple technique can help to solve nitrogen problem in ponds.
