Aqueous Systems of Dissolved Oxygen in Reservoir

Abstract

Oxygen plays a crucial role in aquatic ecosystem particularly for supporting aquaculture and hydropower. In freshwater, importance of oxygen is for metabolic respiration and balance for heterotrophic organisms. Oxygen is also involved in various chemical equations in which compounds influence each other. To prevent oxygen depletion, understanding the changes in DO and all interactions with other water qualities been reviewed with purposed to know aqueous systems work. Photosynthesis by phytoplankton is the main production of dissolved oxygen. Carbon dioxide as output from respiration of microorganisms and degradation of organic inputs and light as energy transformation of photosynthesis is needed in the process. The temperature level is involved as a determinant of gas solubility. There is also gas exchange from atmosphere to water as oxygen diffusion that move toward an equilibrium. However, dissolved oxygen absorption occurs in high demand in case an oxidizer in the degradation of organic matter which come into the reservoir. In eutrophic condition, the abundance of phytoplankton also requires oxygen for respiration, especially at night. The consumption of dissolved oxygen often spurs reservoir managers to monitor the input into the reservoir to build an aerator as a form of ensuring adequate dissolved oxygen circulation.

“…The next important ecosystem service evaluated in this study was the ability of green spaces to produce oxygen. Although this service is most often mentioned in the context of useful functions of woody plants, this ecosystem function on a global scale is not so substantial compared to the production of oxygen by aquatic ecosystems (Liqoarobby et al, 2021). However, at the local level, it requires research and evaluation to regulate the oxygen-carbon balance of urban ecosystems.…”

Vibrio Species and Cyanobacteria: Understanding Their Association in Local Shrimp Farm Using Canonical Correspondence Analysis (CCA)

“…The heightened DO levels observed in the shrimp farm can be attributed to the installation of an aeration system designed to ensure adequate DO levels [ 38 ]. The presence of phytoplankton, particularly through photosynthesis, also serves as the primary source of DO in water [ 39 ]. Additionally, factors that can have an effect on DO concentrations in water include temperature and salinity.…”

“…Bacteria begin to use the oxygen bound in nitrate at this point. These processes are of utmost relevance because reduced species of nitrogen frequently contaminate water (Liqoarobby et al, 2021).…”
