Sorption behaviour of xylene isomers on biochar from a range of feedstock

Hamid Rajabi et al.

Summary: In this study, the potential of biochar as a low-cost containment solution for contaminated solids by volatile organic compounds (VOCs) was investigated. Experimental results showed that high-temperature biochar with similar surface chemistry had higher sorption efficiency due to porous structure and pore size distribution. Biochar samples with higher specific surface area and volume of mesopores exhibited the highest sorption capacity for xylene isomers. The Elovich kinetic model was found to best describe xylenes' sorption on biochar, indicating pi-pi stacking and hydrogen bonding as the main mechanism of sorption.

Application of biochar as an innovative substrate in constructed wetlands/biofilters for wastewater treatment: Performance and ecological benefits

Shengjiong Deng et al.

Summary: Biochar as a substrate amendment in constructed wetlands/biofilters shows promising performance in removing nitrogen, phosphorus, organic contaminants, heavy metals, and pathogens, while also providing ecological benefits such as enhancing macrophyte growth and reducing greenhouse gas emissions. The unique mechanisms involved in these benefits, particularly the roles of microorganisms, are analyzed and highlighted. The potential for recycling spent biochar media in constructed wetlands/biofilters for soil amelioration/remediation is proposed.

Fluidisation characteristics of granular activated carbon in drinking water treatment applications

O. J. Kramer et al.

Summary: Granular activated carbon (GAC) filtration is crucial in drinking water treatment for filtering and adsorbing organic pollutants. The backwash procedure of GAC beds is equally important in preventing particle accumulation and reducing operation costs. Developing prediction models for backwashing is essential for optimizing performance and sustainability in water treatment.

Fractal permeability model for dual-porosity media embedded with natural tortuous fractures

Yafei Luo et al.

Summary: Coal is a dual-porosity medium with internal pore-fracture structure, and understanding the relationship between permeability and pore-fracture structure characteristics is crucial for predicting coalbed methane productivity accurately. A new fractal permeability model of dual-porosity media embedded with natural tortuous fractures has been established in this study, showing improved accuracy in predicting coal seam permeability compared to traditional models. The numerical simulation results demonstrate strong power-law relationships between coal permeability and fracture geometric characteristic parameters, validating the proposed model's accuracy.

New hydraulic insights into rapid sand filter b e d backwashing using the Carman?Kozeny model

Onno J. I. Kramer et al.

Summary: It is shown in the research that the shape factor for irregularly shaped grains is not a constant property, but dependent on fluid properties, increasing in fluidized state. Unstable packed beds under moderate up-flow conditions may behave pseudo-fixed, leading to a decrease in bed voidage and drag coefficient. This contradictory behavior can be explained by the collapse of local channels in the bed, resulting in a more uniform flow distribution and improved surface for flow-through.
