The present investigation was carried out to assess the operation of a pilot-scale submerged membrane bioreactor (SMBR) for treatment reactive dye and textile wastewater. SMBR model conducted by using polyethersulfone (PES) hollow fibre with continuous flow mode at different HRTs 8, 6 4 h, 90 days. During entire operation, average permeate flux, TMP, F/M ratio OLR found be 19 (L/m²/h), 2.6 (psi...

Polyethersulfone (PES) films are widely employed in the construction of membranes where there is a desire to make surface more hydrophilic. Therefore, UV photo-oxidation was studied order oxidize PES and increase hydrophilicity. using low pressure mercury lamps emitting both 253.7 184.9 nm radiation were compared with only photons. The modified surfaces characterized X-ray photoelectron spectro...

Abstract In peel, tests between polycarbonate/polyethersulfone (PC/PES) blends with different compositions and thermoplastic polyurethane (TPU) films thicknesses a large decrease in energy release rate is observed when the PC/PES formed co‐continuous structure. With SEM analysis, XRD measurements, selective PC etching of failed samples, finite element modeling stress distributions region this f...

Membrane separation is an important processing technology used for separating food ingredients and fractionating value-added components from food processing byproducts. Long-term performance of polymeric membranes in food protein processing is impeded by the formation of fouled layers on the membrane surface as a result of protein adsorption onto the membrane surface. Surface modification of sy...

Polyethersulfone (PES)-based anion exchange blend membranes were prepared from quaternized-PES (Q-PES) and N-Methyl-2-pyrrolidone (NMP) casting solutions with water as coagulant via non-solvent induced phase inversion. The compatibility of the blend system was investigated through thermodynamic studies while membrane formation was determined using the cloud point techni...

Polyethersulfone-sulfonated polyethersulfone (PES-SPES)/NaY zeolite/nylon sandwich structure membranes were prepared and used to adsorb Cu2+ from water. The adsorption kinetics, isotherm, dynamic experiment, reusability discussed. experimental data showed that the Langmuir isotherm model, Dubinin–Radushkevich (D-R) pseudo-first-order kinetic model can well represent of on membrane, indicating a...

Tangential flow filtration (TFF), which has been widely adopted to concentrate a diverse array of microbes from water, is a promising method of microbial separation or removal. However, it is essential to select an optimal membrane suitable for the specific filtration application. This study evaluated two different scales of TFF systems for concentrating and separating microbes (including bacte...

Agilent Captiva Premium PES syringe filters are evaluated and compared to other suppliers’ PES and PVDF syringe filters for the risk of losing protein during filtration. Captiva Premium PES syringe filters demonstrate low protein binding with excellent recovery for biological samples, especially for ‘sticky’ proteins at low concentrations. In addition, an assessment of filter extractables on LC...
