In this study, a novel system for contacting gases and liquids, which may be suitable for many applications involving gas-liquid contact or gas-liquid reactions, has been developed and characterized. The system consists ...

This study investigates the characterization and the ability of polyvinyl alcohol (PVA) gel to be used in the area of wastewater treatment as biomass immobilization matrix. The PVA matrix was prepared through the ...

Carbon dioxide (CO2), as one of the major greenhouse gas emissions, has attracted much attention in the world. Magnetite Fe3O4 nanoparticles have a tendency to aggregate in solution to reduce their surface energy due to ...

CO2 is one of the main greenhouse gases that causes global warming, leading to a global detrimental impact on the environment, economy, and society as a whole. Carbon capture is regarded as an important and effective ...

Chlorophenols (CPs) are hazardous pollutant that are commonly encountered as major constituents of several types of wastewater such as industrial, refinery and pharmaceutical wastewater. They are also exposed to the ...

The present work evaluates a new process for the capture of CO2 and the reduction of water salinity. It is based on the Solvay process without the use of ammonia and involves the reaction of CO2 with saline water such as ...

Membrane technology is a novel and promising method for CO2 capture among the separation approaches. The chapter first introduces the various membrane materials and their preparation methods. Especially the zeolites membranes ...

The aim of this research was to investigate the potential of raw and iron oxide impregnated carbon nanotubes (CNTs) as adsorbents for the removal of selenium (Se) ions from wastewater. The original and modified CNTs with ...

Grit is routinely removed at the headworks of municipal wastewater treatment works to limit its onerous impact on downstream processes. Grit separation technologies are normally based on sedimentation of a homogeneous ...

Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
