Summary: The study evaluated the impact of hydrothermal pretreatment (HTP) on anaerobic digestion (AD) of sewage sludge at different temperatures. HTP increased organic matter destruction and methane production, but high temperature HTP led to increased propionate levels and lower methane production. The bacterial communities in the digesters were significantly affected by HTP, while the archaeal communities showed minor changes. The highest net energy gain was observed in the control group, and a heat recovery greater than 85% is needed to achieve a similar net energy gain with HTP.

Summary: The study investigated the individual and combined effects of sulfamethoxazole (SMX) and oxytetracycline (OTC) on an enhanced biological phosphorus removal (EBPR) system. OTC at 5 mg/L led to filamentous bulking and collapse of the EBPR system, while the inhibition effects of SMX and SMX + OTC on P removal, COD removal, glycogen transformation, and extracellular polymeric substances content were reversible with prolonged operation. Factors like the presence of nitrification inhibitor, high pH, and low tetX abundance limited the removal of SMX and OTC in the system.

Summary: Anaerobic digestion combined with hydrothermal treatment is an attractive technology for sewage sludge treatment and resource recovery. The study systematically characterizes the transformation of important heavy metals in sewage sludge during AD with pre- or interstage HT. Results show that both Cu and Zn predominantly occur as sulfides in HT hydrochars, with subsequent AD favoring the formation of specific metal species. These findings have important implications for understanding the fate and mobility of heavy metals in sludge-derived hydrochars and AD solids.

Summary: This study investigated the effects of tetracycline (TC) on bio-electrochemically assisted anaerobic methanogenic systems (An-BES) for wastewater treatment. The results showed that TC had minimal effect on methane production at low concentrations, but significantly reduced methane production and current output at high concentrations. TC was predominantly removed through adsorption, and the application of voltage enhanced its removal. The electrode biofilms had higher abundance of propionate oxidizing bacteria and methanogens, while antibiotic resistance genes were less abundant compared to suspended cultures. TC inhibited certain functional microorganisms and pathways, leading to decreased performance of An-BES systems.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
