Summary: One of the main symptoms of eutrophication is the increase in phytoplankton biomass, including cyanobacteria. To control eutrophication, reducing the external nutrient load and implementing in-lake interventions are necessary. Floc & Sink (F&S) technique, which applies a low dose of coagulants and ballasts to remove cyanobacteria biomass, is effective for deep lakes with a higher external nutrient load. The study evaluated the efficiency of the F&S technique in a tropical reservoir and found that combined treatments were more effective in removing algal biomass, with variations in efficiency observed over time and spatially.

Summary: The re-establishment of submerged macrophytes is crucial in transforming turbid into clear water systems in shallow lake restoration. However, this process may be inhibited by juvenile omni-benthivorous fish. The application of Lanthanum modified bentonite (LMB) can potentially weaken the negative effects of these fish and benefit submerged macrophytes.

Summary: The addition of Phoslock(R) significantly decreased the bioavailable forms of phosphorus in sediments, leading to a decrease in total biomass and relative growth rate of Myriophyllum spicatum, but an increase in root biomass. This may help inhibit phosphorus release and resuspension of sediments and promote the restoration of the lake ecosystem.

Summary: Lake restoration using phosphorus inactivation method can lead to the creation of an active sediment layer with higher P adsorption abilities, providing important data on the durability of restoration effects. The continuous phosphorus adsorption by the active layer in post-restoration period contributes to the increased P binding molar ratio over time.

Summary: Combining a low dose of aluminum sulfate with drinking water treatment residual (DWTR) effectively sinks Microcystis in eutrophic lake water and inactivates phosphorus in lake sediment. DWTR has a higher P sorption capacity compared to local soil, and desorption of Al, Fe, Ca, and N from DWTR can marginally increase their concentrations in the water column.

Summary: The importance of controlling internal P pollution in lake restoration has been widely recognized. While the main focus has been on cutting soluble P migration from sediment to overlying water, another form of internal P pollution, phytoplankton-available suspended particulate P (SPP) pollution, has been identified. SPP pollution mainly occurs under aerobic conditions due to sediment resuspension and soluble P adsorption by suspended particles. Compared to soluble P, SPP pollution has more complex loading pathways and P activation mechanisms, making control measures more challenging. Further research is needed to understand and regulate phytoplankton-available SPP pollution for effective lake restoration.

Summary: Nutrient enrichment in lakes is a global issue that affects the health, biodiversity, and services provided by lakes. The use of oxygen nanobubbles as a geoengineering technology shows promise in remediating low oxygen conditions and alleviating eutrophication linked to high internal nutrient loads. However, further research is needed to address scalability, environmental impacts, and social acceptance.

Summary: The study demonstrates that high phosphorus concentrations stimulate excessive growth of Cladophora in Lake Ontario, causing various issues. Simulation results show that phosphorus removal by chemically enhanced secondary treatment is inadequate in alleviating nuisance conditions, while tertiary treatment with chemically enhanced secondary treatment and ballasted flocculation can eliminate phosphorus-saturated conditions associated with the Duffin Creek wastewater treatment plant effluent, providing local relief from nuisance conditions.

Summary: Lake geo-engineering, such as submerged macrophyte restoration, is important for recovering the ecological functions of eutrophic shallow lakes. However, research on the long-term variations in plankton and their correlations with environmental variables after submerged macrophyte restoration is limited. In this study, the researchers monitored the plankton in West Lake, China on a monthly basis and found that submerged macrophyte restoration led to changes in the composition and population of phytoplankton. The characteristics of submerged macrophytes, especially Vallisneria natans, strongly influenced the dominant phytoplankton. The researchers also found that submerged macrophytes affected phytoplankton growth by releasing allelochemicals and altering water nutrient levels.

Summary: By comparing the trophic structure of shallow lakes in tropical and subtropical regions in South America, researchers found that despite lower fish biomass in tropical lakes, there was no significant impact on zooplankton or phytoplankton communities. The study suggests that warming will have relatively minor impacts on the pelagic trophic structure of shallow subtropical lakes, supporting the idea of weaker trophic cascades in warm (sub)tropical lakes compared to temperate ones.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
