Inorganic nanopores occurring in the shale matrix have strong hydrophilicity and irreducible water (IW) film can be formed on inner surface of pores making gas flow mechanisms more complex. In this paper, existence inorganic is considered, and, based Knudsen number (Kn) correction pores, a apparent permeability model nano-pores established. The effect Kn permeability, ratio with pore radius IW ...

Membrane reusability determines the economic sustainability of separation process. However, membrane was deduced by antifouling properties, while actual reuse performance using palm oil mill effluent (POME) is rarely reported. This study investigates nano-Fe3O4/PVDF (PVDF1) for POME treatment. The chemical oxygen demand (COD), total suspended solid (TSS) permeate, molecular weight cut off (MWCO...

Hydrous ferric oxides (HFO) are efficient sorbents for inorganic and organic pollutants and therefore have great potentials in environmental science and engineering applications. Freezing and thawing of HFO suspensions leads to the formation of dense HFO aggregates. It facilitates the handling and increases the drying rate of HFO. In this study, we used a combination of pycnometry, gas adsorpti...
