Application of the technology of water lifting and aeration on improving water quality in a Deep Canyon Reservoir – a case study from northern China

Effects of rainfall patterns on water quality in a stratified reservoir subject to eutrophication: Implications for management

“…High inflow volumes have been observed to transport large amounts of suspended matter with large loads of particulate nitrogen and phosphorus into reservoirs, including the Shibianyu Reservoir (Huang et al, 2014b). This process increased the accumulation of the endogenous pollutant load because particulate-associated nutrients were easily deposited in the reservoir area.…”

“…The landscape upstream and surrounding the reservoir is largely unmodified and consists primarily of hills covered with forest with limited human activity, ensuring that the inflow water is in good condition most of the time. However, the inflow water quality deteriorates during storm rainfall periods due to soil erosion, with high concentrations of suspended matter and nutrients that are transported into the reservoir (Huang et al, 2014b).…”

“…The Shibianyu Reservoir is a stratified eutrophic reservoir, with annual average concentrations of total nitrogen (TN) and total phosphorus (TP) of 2.8 mg/L and 0.041 mg/L, respectively (Huang et al, 2014b). Cyanobacterial blooms in the surface water and the release of endogenous pollution from bottom sediments during the stratification period strongly influence the reservoir water quality.…”

Effects of Seasonal Thermal Stratification on the Functional Diversity and Composition of the Microbial Community in a Drinking Water Reservoir

“…Our previous studies indicated that the mixing period of the Jinpen Reservoir ends at the beginning of June, followed by a re-stratification period. Stratification became stable by mid-June, and lasted until December [1,22,23]. According to our previous results, we focused on the changes in microbial communities driven by thermal stratification, with regard to both the functional diversity and structure, in the Jinpen Reservoir.…”

Study of the application of the water-lifting aerators to improve the water quality of a stratified, eutrophicated reservoir

“…Low-temperature water reached the surface and initially moved horizontally in all directions due to its inherent kinetic energy; the water then moved downward because it was denser than the background water. However, the water changed direction and moved upward because of the buoyancy resistance from the stratification (Huang et al, 2014b).…”
