Abstract Membrane fouling is the major factor limiting wider applicability of membrane-based technologies in water treatment and separation purification processes biorefineries, pulp paper industry, food industry other sectors. Endeavors to prevent minimize requires a deep understanding on mechanisms their relative effects. In this study, Brunauer-Emmett-Teller (BET) nitrogen adsorption/desorption technique was applied get an insight into pore-level membrane phenomena occurring...
Bipolar membrane electrodialysis (EDBM) can be applied for the electro-acidification of skim milk (SM) using a water-splitting effect. A new method acidification SM gives opportunities and perspectives to development alternative novel products in dairy industry. The present study assessed effect temperatures from 5 °C, 10 15 20 25 °C 30 EDBM on terms mineral composition side streams. mechanisms ion transport during by bipolar membranes (BMs) coupled with cation-exchange (CMs) were...
In this study, we evaluate the performance of modified polysulfone (PSF) ultrafiltration (UF) membranes, which incorporate deep eutectic solvents (DES), in treating stormwater laden with natural organic matter e.g. chemical oxygen demand (COD) and total suspended solids (TSS). We also aim to understand how these substances, COD, TSS, from water source contribute fouling synthesized membranes. PSF membranes were using a non-solvent induced phase separation technique integrated varying...
The modelling of the ma ss transfer in pervaporation is one fundamental aspects to understand and therefore improve process performance. This paper reviews different models analyse predict mass transport through selective layer pervaporation. It provides an overview combined with some guidance about proposed literature applicability range these models. reviewed cover two key steps pervaporation: (1) sorption into membrane, (2) diffusion membrane. For individual will be as well covering...
Molasses is a sugar mill by-product with low value that today used primarily for animal feed. However, molasses contains large amounts of sucrose which, if purified, could be other purposes. In this study, purification by membrane filtration using ceramic tubular ultrafiltration (UF) and nanofiltration (NF) was examined. NF purifies removing small compounds, whereas UF removes larger compounds. Based on our results, high fluxes obtained, it possible to clean the membranes sufficiently from...
Membrane processes are essential for the success of lignocellulosic biorefineries, but membrane fouling is still a major problem and single most important reason relatively slow acceptance technology in this industrial application. It therefore utmost importance to find methods that enable study development when processing new types feed solutions. Although ex situ analysis allows composition layer be determined, leading its build-up remain unknown. In study, quartz crystal microbalance with...
The pulp and paper industry is one of the most important industrial sectors worldwide, has considerable potential for sustainable fractionation lignocellulosic biomass to provide valuable compounds. Ultrafiltration (UF) a suitable separation technique profitable production hemicelluloses from process water thermomechanical pulping (ThMP), but limited by membrane fouling. Improvements in cleaning protocols new alternative agents are required ensure long lifetime, thus process. This study,...
Downstream processing of ABE fermentation broth is challenging issue. In this work, results the application both hydrophobic and hydrophilic commercial membranes during pervaporation aqueous mixtures were investigated presented. Hydrophobic experiments performed using ABE-water containing 0–5 wt% organics in feed, membranes: POMS, PEBAX, Pervap™4060. Separation factor Pervaporation Index employed to discuss results. Pervap™4060 membrane revealed best separation performance removal components...

Pervaporation is a membrane separation process with considerable innovative possibilities in the area of biotechnology. Above all, combination bioreactor and pervaporation has potential longer term as an alternative to conventional batch processes.

Even though membrane technology is used in numerous industrial applications, fouling still a major challenge. Valuable information on the formation kinetics and structure of layer can be obtained by situ real-time monitoring. Quartz crystal microbalance with dissipation monitoring (QCM-D) enables study adsorptive model membrane. However, so far, there has been no in-depth investigation as to what extent observations from QCM-D relate during filtration. This gap here approached comparing...
In this study, the partitioning of minerals in ultrafiltration (UF) streams skim milk using cross‐flow (CF‐UF) and dead‐end (DE‐UF) was investigated 50 kDa membrane at different temperatures (5, 10, 25, 35, 55°C). CF‐UF showed higher protein retention (6.02–10.9%) compared with DE‐UF (3.44–4.70%), along more calcium, values ranging from 29.8 to 41.5 57.8 112 mM for CF‐UF, respectively. Ionic calcium permeates varied less (2.48–1.18 mM) than (3.11–0.98 mM). The insights provided study can be...
