Summary: Biochar has been found to be an effective carrier for microorganisms due to its physicochemical properties and microenvironment. In this study, the adhesion behavior of Bacillus salmalaya 139SI and Bacillus amyloliquefaciens NBRC 15535 on oil palm kernel shell (OPKS) biochar was investigated. The pseudo-second-order kinetics model accurately described the adhesion process, and the adhesion equilibrium was reached after 80 minutes with a cell concentration of 10^8 CFU/g. Field Emission Scanning Electron Microscopy images revealed the formation of microcolonies and a biofilm structure on the biochar surface, and electron dispersive spectroscopy analysis suggested that bacteria attached to mineral-rich regions on the biochar surface, which may enhance their survival.

Summary: This study investigates the use of charcoal and sago bark ash as soil amendments to improve phosphorus fixation in acid soils and enhance nutrient utilization. The results show that the combined use of charcoal and sago bark ash decreases phosphorus adsorption and increases phosphorus desorption. The organic matter in charcoal reduces phosphorus adsorption capacity by providing negatively charged surfaces, while sago bark ash neutralizes soil acidity and increases phosphorus desorption. These improvements contribute to replenishing soil phosphorus and promoting maximum crop production.

Summary: This study investigates the attenuation and release behavior of copper ions in a high solids/high salinity application using synthetic tailings treated with inline flocculation. The results show that the polymer-treated tailings have a higher capacity to adsorb and retain copper ions compared to untreated slurry, with the capability to preserve heavy metal ions across a wide pH range (2-10), which is important for long-term mine closure and rehabilitation purposes.

Summary: In this study, biochar obtained from poplar wood gasification was used to adsorb xenoestrogens and a herbicide from water. The surface micromorphology and functional groups composition of biochar were investigated using scanning electron microscopy and Fourier-transform infrared spectroscopy. The adsorption kinetics showed the formation of strong bonds between biochar and the compounds, and the adsorption isotherms were described by several mathematical models. Biochar exhibited strong adsorption ability at higher temperatures, and desorption was slow and scarce. This study highlights the excellent potential of biochar as a low-cost biosorbent for retaining organic compounds permanently.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
