Polymer-based membranes have advanced or novel functions in the various membrane separation processes for liquid and gaseous mixtures, such as gas separation, pervaporation (PV), reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), other critical applications of water purification, solvent concentration, recovery [...]

This study investigated the use of ceramic membranes to remove total suspended solids (TSS), organics (expressed by chemical oxygen demand, COD), and bisphenol A (BPA) via microfiltration (MF, pore size 0.45 μm) and ultrafiltration (UF, cutoff 150 kDa) in post-treatment of effluents from aerobic granular sludge reactors (GSBRs). The efficiency of removal of COD, BPA, and TSS in MF was similar t...

A membrane filtration system was used to remove organic compounds, suspended solids, colour and turbidity from anaerobically treated dairy wastewater. Direct microfiltration (MF), ultrafiltration (UF), MF-UF and a combination of UF with coagulation using two conventional coagulants were investigated. The installation with ceramic membranes was operated at a pressure of 0.15 MPa (MF) and 0.3 MPa...

The direct utilisation of side streams from membrane processing and evaporation is great potential interest for dairies to reduce water consumption. In an analytical screening 89 industrially obtained streams, samples varied in pH conductivity broad ranges 4.22 7.56 0.001 0.949 Siemens per meter, respectively. Detailed compositional data the enabled assessment their applicability as diafiltrati...

The aim of this study was to produce a colloidally stable whey protein concentrate enriched in β-casein. Microfiltration (MF) skim milk completed at ∼7 °C (pore size 0.1 μm) followed by ultrafiltration the MF permeate ∼9 β-casein-whey fraction (BWPC). casein:whey ratio BWPC system ∼25:75. Skim then added retentate level supplying 0, 0.1, 0.3 and 0.5% (w/w) total protein, evaporation spray dryin...

The effects of Ca2+ (0–75 mg/g pectin) and sucrose (0–40%, w/w) or sweeteners (0.1, 0.05% stevia saccharin) pH (3.0, 4.5, 6.8) on the rheological properties gels formed with sunflower pectins purified by conventional method (Conv-pectin), microfiltration (MF-pectin) ultrafiltration (UF-pectin) were investigated. main objective was to develop alternative low-calorie pectin without altered gelati...

Poultry slaughterhouses produce a large amount of wastewater, which is usually treated by conventional methods. The traditional techniques face some challenges, especially the incapability recovering valuable nutrients and reusing water. Therefore, membrane technology has been widely adopted researchers due to its enormous advantages over Pressure-driven membranes, such as microfiltration (MF),...

The adsorption of trace contaminants on natural particles is of great interest as this adsorption enhances the possibility of removing these with low pressure filtration such as MF and UF. This study shows that natural hormones such as estrone and estradiol will adsorb to natural particles both organic and inorganic. Experiments have shown that the adsorption capacity of organics is a factor of...

A high cell density perfusion process of monoclonal antibody (MAb) producing Chinese hamster ovary (CHO) cells was developed in disposable WAVE Bioreactor™ using external hollow fiber (HF) filter as cell separation device. Tangential flow filtration (TFF) and alternating tangential flow (ATF) systems were compared and process applications of high cell density perfusion were studied here: MAb pr...
