Invent of a simultaneous adsorption and separation process based on dynamic membrane for treatment Zn(II), Ni(II) and, Co(II) industrial wastewater
Heavy metal ions wastewater threatens the environment. Removal of heavy metal ions at low concentrations using bio-sorbents is a new solution, but separating the adsorbent from the fluid is also difficult and costly. In this work, a plug reactor equipped with the dynamic membrane (DM) was used for t...

Heavy metal ions wastewater threatens the environment. Removal of heavy metal ions at low concentrations using bio-sorbents is a new solution, but separating the adsorbent from the fluid is also difficult and costly. In this work, a plug reactor equipped with the dynamic membrane (DM) was used for the adsorption of Zn (II), Co(II), and Ni(II) ions from industrial wastewater. DM module equipped with vibrators for decreased membrane fouling. Central composite design (CCD) was applied to the experiments design. Brunauer–Emmett–Teller (BET) theory, scanning electron micro-scope (FE-SEM), and Fourier transform infrared spectroscopy (FT-IR) were employed to characterize and analyze. The Sargassum glaucescens nanoparticles (SGN) and hydroxyapatite with 50–150 nm and 10–20 μm of particle size and 12.99–172.46 m2g-1 of specific surface area were tested as adsorbent. DM support prepared with electrospinning of chitosan (Cs) and polyvinyl alcohol (PVA) on the polyester web. Cs/PVA nanofibers were cross-linked with the heat at 110 °C for 10 h.
