The interest in separating and concentrating bioactives minerals from seaweeds extracts is growing due to large health benefits of these substances. aim this study was investigate the separation components Fucus vesiculosus seaweed by tangential ultrafiltration apply Hermia’s models adapted crossflow understand fouling mechanism. influence membrane cut-off varying 5 150 kDa, velocity 0.081 0.09...

In this work we report the experimental assessment of the performance of a new catalytic hollow fiber reactor with supported Pd catalyst for nitrite removal from polluted waters. The reactor configuration facilitates working at low flowrate and hydrogen concentrations in order to improve the selectivity of the reduction reaction towards nitrogen, thus, inhibiting the formation of ammonia. Pd ca...

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...

In the production of polymeric membranes used in water treatment by non-solvent-induced phase separation (NIPS) method, materials membrane casting solution and interaction these greatly affect properties performance obtained membranes. this study, polyethersulfone (PES) are produced NIPS method using two different solvents, dimethyl sulfoxide (DMSO) N-methyl-2-pyrrolidone (NMP), polyvinylpyrrol...

Diffusion dialysis (DD) employing anion exchange membranes (AEMs) presents an attractive opportunity for acid recovery from acidic wastewater. However, challenges exist to make highly permeable AEMs due their low coefficient (Uacid). Here, a series of porous and fabricated based on chloromethyl polyethersulfone (CMPES) membrane substrate with crosslinking quaternization treatments is reported. ...

Affinity membranes have the potential to enhance specific adsorption of toxins, however, they suffer from insufficient hemocompatibility and low therapeutic efficiency during blood detoxification therapy. Herein, we combine an affinity membrane with a bioreactor develop purification cell functions. To fabricate membrane, polyethersulfone (iPES) macroporous support layer was prepared by phase in...

The current study aimed to develop an anaerobic wastewater treatment and reuse module enabled by thermophilic bioprocessing, a microbial fuel cell (MFC) ultrafiltration (UF) treatment. A previously unexplored consortium based on Thermoanaerobacterium thermosaccharolyticum Arcobacter sp. was used remove ~73% of chemical oxygen demand (COD) from under conditions (CODi = 200 mg/L). subsequent MFC ...
