The amount of air that can remain dissolved in a water solution is a function of pressure and temperature. This relationship is governed by Henry’s Law. The graph below demonstrates the physical phenomenon of the air release from water. As an example, at a constant absolute pressure...
Dissolved Oxygen refers to the amount of oxygen gas that is dissolved in water, which is a critical parameter in aquaculture operations. It can be measured using oxygen meters or chemical test kits, and its concentration is influenced by factors like temperature, salinity, and altitude. ...
Dissolved oxygen (DO) is a key indicator of water quality and the health of an aquatic ecosystem. Aspiring to reach a more accurate forecasting approach for DO levels of natural streams, the present work proposes new graph-based and transformer-based deep learning model...
The temperature effect If water is too warm, there may not be enough oxygen in it. When there are too many bacteria or aquatic animal in the area, they may overpopulate, using DO in great amounts. Oxygen levels also can be reduced through overfertilization of water plants by run-off from...
Data can be made available 24/7 through an online datacenter. Dissolved oxygen measurements can be viewed in real time, or as a graph to see trends. Automated alerts can be sent via text or email in real time when dissolved oxygen falls below minimum standards. ...
To convert oxygen tension to dissolved oxygen concentration, it is necessary to know the solubility of oxygen in the liquid at the temperature and pressure of measurement. For example, if the dissolved oxygen tension measured using an oxygen electrode is 60% air saturation and the solubility of ...

Ca2+, Mg2+, Na+, SO4 2−, and Cl− were the inputs. Wavelet-ANFIS outperformed the Wavelet-ANN model. Salami et al. [33] used ANN models to predict dissolved oxygen (DO) and total dissolved solids (TDS). The ANN models were reliable for predicting water quality indicators. Amano...
