Summary: Energy production in constructed wetlands, specifically vertical partially saturated constructed wetlands (VPS-CWs), can enhance the growth of evaluated plant species and efficiently remove pollutants. The generation of bioelectricity with the use of domestic wastewater as a substrate improves plant development and stimulates the growth and germination of new shoots. Different removal efficiencies were observed between systems planted with different plant species, with Canna hybrids showing better results in terms of TKN and P-PO4 removal.

Summary: Burning surplus agricultural residues is a common practice worldwide, but it leads to emissions and nutrient loss. Constructed wetlands can be a sustainable solution by using these residues as substrates for growing ornamental plants and generating income. This study explored the use of agricultural residues and biochar as substrates in constructed wetlands for growing ornamental plants.

Summary: A hybrid constructed wetland system combining horizontal and vertical flow was used to treat carbon-deficient synthetic dyeing wastewater. The results showed that the system could effectively remove azo dyes from low-carbon dyeing wastewater. In the horizontal wetland, organic waste products served as the carbon source for microbial dye degradation, resulting in 90% color removal. The vertical wetland removed dye degradation organics, ammonium-nitrogen, and organic-nitrogen.

Summary: The use of constructed wetlands (CWs) for wastewater treatment has attracted considerable attention worldwide. One innovative approach is the use of ornamental flowering plants (OFP) in CWs, which not only enhances the aesthetics of the system but also allows for the production of commercial flowers. This study identified the main OFP used in CWs, their phytoremediation effects, and the countries involved in this research.

Summary: This study evaluated the use of climbing ornamentals and ornamental plants in vertical flow constructed wetlands for greywater treatment. The findings showed that sand with or without saturation zone had higher removal rates for turbidity and Chemical Oxygen Demand compared to vermiculite. Vegetated systems also had slightly higher removal rates than unvegetated systems. Lonicera japonica and Callistemon laevis were found to be more well-adapted to the constructed wetland systems compared to Trachelospermum jasminoides. Overall, the application of climbing and ornamental plants in vertical flow constructed wetlands seems promising in improving aesthetic appearance and increasing public acceptance.

Summary: This study found that emerging substrates such as biochar, zeolite, and pyrite had higher removal efficiency for sulfamethoxazole (SMX) compared to conventional gravel substrate. The microbial compositions and functions varied among different substrate constructed wetlands, which influenced the resistance pattern and metabolism pathways of microbiomes under SMX stress. Additionally, nine transformation pathways with 15 transformation products were detected. This study provided a comprehensive insight into the processes and mechanisms of SMX removal in constructed wetlands with different substrates, which can guide substrate selection for enhanced micropollutant removal.

Summary: The Argemone genus includes weed species that are of great importance in traditional medicine due to the presence of secondary metabolites, especially alkaloids, distributed in all tissues of the plants. Furthermore, the seeds of these species contain a significant amount of oil. Therefore, Argemone species have the potential to be a non-edible crop for the production of biofuels and a source of valuable by-products for the agrochemical and pharmaceutical industries.

Summary: This study investigated the temporal dynamics of bacterial communities in Lake Cajititlan and their genes associated with biogeochemical cycles during the rainy season. The results showed significant temporal variations in the composition of bacterial communities, with pH, dissolved oxygen, oxidation-reduction potential, and other climatological parameters being most correlated with the bacterial communities and their functional profiles. The study enriches our understanding of the interaction between bacterial communities and major biogeochemical processes in eutrophic subtropical lakes.

Summary: The presence of SARS-CoV-2 in wastewater in Mexico was studied, and a correlation was found between the percentage of treated wastewater and the number of COVID-19 positive cases. The study highlights the need to increase wastewater treatment coverage and emphasizes the potential of untreated wastewater as a bioindicator for virus presence. However, the wastewater treatment systems in Mexico are fragile and limited in coverage.

Summary: This study evaluated the removal of pollutants from municipal and swine wastewater using PSV-CWs and FFV-CWs. The results showed that PSV-CWs performed slightly better in terms of plant adaptation, vegetative development, and TSS elimination compared to FFV-CWs. However, FFV-CWs showed better performance in TN, N-NH4, and N-NO3 removal in systems with vegetation. There were no significant differences between the two types of constructed wetlands for COD and TP removal, but significant differences were found between systems with and without vegetation.

Summary: This study evaluated the treatment of tequila vinasse (TV) in two types of constructed wetlands (CWs), showing similar high removal efficiencies for various pollutants. The highest removal percentages were obtained at 40% of dilution in both horizontal subsurface flow wetlands (HSSFWs) and vertical upflow wetlands (VUFWs). This research demonstrates the potential of CWs as an effective treatment system for TV.

Summary: The aim of this study was to evaluate the water quality in two streams in the Valles region of Jalisco, Mexico and determine if they are being used as disposal sites for tequila vinasse. It was found that the concentration of pollutants in the streams increased as they passed through tequila factories, leading to highly polluted water with little aquatic life. The study highlights the urgent need for tequila companies to implement treatment systems for vinasse to improve the current situation.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

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.
