Abstract ,Membrane, filtration was coupled with heterogeneous Fenton-like catalytic oxidation to resolve the continuously reuse problem of fine catalysts. A new integrated (MHF) reactor was developed to allow the active species to remain in the reaction system. The reactor consisted of a newly prepared heterogeneous catalyst, superfine Fe-immobilized carbon (FeOOH–C) particles, and a submerged ...

Membrane separation is known as an efficient technique for oily wastewater treatment. In the present study, cellulose acetate (CA) was introduced into the polyetherimide (PEI) solution in order to enhance hydrophilicity and the membrane structure for oil–water separation. The hollow fiber membranes were prepared via a phase-inversion process.
