Summary: This article critically reviews the current knowledge on the physical, chemical and biological mechanisms involved in the removal of biogenic taste and odour (T&O) compounds by granular and biological activated carbon (GAC and BAC). The study determines that the removal mechanisms, such as physiosorption in the micropore region, have been well studied and understood. However, further research is needed to understand how operational conditions and carbon characteristics affect the development and performance of the biofilm in BAC. Future studies should focus on the adsorption and biofiltration of T&O compounds other than geosmin and 2-methylisoborneol (MIB), the isolation and characterisation of microorganisms capable of biodegrading T&O compounds, and the identification of biodegradation pathways and by-products in large scale systems.

Summary: This study investigated the contributions of adsorption and biodegradation to the removal of MIB and geosmin in GAC harvested from drinking water treatment plants in the Great Lakes region. It was found that GAC had significant adsorption and biodegradation capacity, and C-14-glucose respiration rate was identified as a potential indicator for GAC biodegradative capacity. Non-targeted screening analysis also identified potential biodegradation products. The findings of this study provide valuable insights for better understanding the use of GAC in water treatment.

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: Efficient anaerobic digestion relies on the cooperation of different microorganisms with different metabolic pathways. This study investigated the effects of different operational modes and the addition of powdered activated carbon (PAC) on ethanol metabolic pathways. The results showed that the SBR mode and the presence of CO2 facilitated ethanol metabolism towards propionate production, while the CFR mode with extended solids retention time enriched Geobacter. Adjusting operational modes and PAC addition can modulate anaerobic ethanol metabolism and enrich Geobacter.

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.
