Summary: The A-01 wetland treatment system was designed to remove metals primarily copper from effluent, with consistent removal of Cu averaging about 80% over 20 years of operation. Most divalent metals were rapidly removed from water and held in sediments shortly after entering the treatment wetland. Highest concentrations of Cu, Pb, and Zn were found in sediment from the first cell in each pair, indicating that most of these metals in the effluent were quickly bound to the sediment.

Summary: This study investigated the variation of heavy metals in a constructed wetland that has been operating for 14 years. The results showed that the sediments of the wetland acted as a sink for heavy metals, with concentrations decreasing along the flow direction. The two common wetland plants exhibited different enrichment performances of heavy metals, and were suitable for phytostabilization. Sediment organic matter was identified as the primary factor affecting the distribution and migration of heavy metals in the wetland system.

Summary: In recent decades, the spread of Elymus athericus has significantly altered the plant community composition and ecosystem services of European marshes. Two ecotypes of E. athericus, adapted to high-marsh and low-marsh environments respectively, have been identified. The plant's ability to oxygenate its rhizosphere, especially during light exposure, contributes to its competitive advantage in low-marsh areas and may aid in its spread under conditions of accelerated sea-level rise.

Summary: Nitrogen loading from diffuse agricultural sources is a major water-quality problem worldwide. Constructed wetlands have proven to be effective in treating runoff and drainage from agricultural lands. This study used a catchment-wetland modelling approach to estimate and quantify the nitrogen input loads into a wetland and evaluate its removal efficiency. The results showed that the Owl Farm constructed wetland had a high capacity for nitrate-N removal, with an average removal rate of 61%. However, the efficiency varied with the inflow from the catchment, with higher removal rates during low-flow periods and slightly lower rates during high-flow periods.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: This study implemented a microaerobic-aerobic configuration in a full-scale municipal wastewater treatment facility and investigated the effects on sludge characteristics, pollutant removal, microbial community, and granulation mechanisms. The results showed successful transition from flocculent-activated sludge to well-defined AGS after two months of operation. The primary pathways for pollutant removal were simultaneous nitrification, denitrification, and phosphorus removal. Moreover, the incorporation of internal separators induced shifts in the flow pattern, which promoted granulation.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
