Abstract This simulation study investigates the impact of material properties on behavior compressible filter cakes. A compression‐permeability (CP) cell is used as a standard experimental technique for characterizing It contains bidisperse particle packing simulated by discrete element method. Using this setup, set crucial varied and their influence macroscopic compression described establishe...

This study reports a numerical approach for modeling the hydraulic resistance of a filter cake of deformable cells. First, a mechanical and osmotic model that describes the volume fraction of solids in a bed of yeast cells as a function of the compressive pressure it experiences is presented. The effects of pressure on the compressibility of yeast cells beds were further investigated both by fi...

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...

With the development of refining industry, treatment refinery wastewater has become an urgent problem. In this study, a ceramic membrane (CM) was combined with Fenton-activated carbon (AC) adsorption to dispose wastewater. The effect process analyzed using excitation–emission matrix (EEM), ultraviolet-visible (UV-vis) and Fourier transform infrared spectroscopies (FTIR). Compared direct filtrat...

The membrane filtration with inside-out dead-end driven UF-/MF- capillary membranes is an effective process for particle removal in water treatment. Its industrial application increased in the last decade exponentially. To date, the research activities in this field were aimed first of all at the analysis of filtration phenomena disregarding the influence of backwash on the operation parameters...

A method based on fluid dynamic gauging (FDG) was developed to investigate the membrane fouling behavior of streams containing dissolved wood components and small particles extracted using a mild steam explosion pretreatment. Industrially chipped softwood subjected saturated at 7 bar for 20 min, followed by cross-flow filtration liquors 10 kDa polysulfone membranes 2 transmembrane pressure. The...

Direct membrane filtration (DMF) is a promising alternative secondary wastewater treatment process in Iceland, where biological not effective due to low strength nature and temperature. This study aims investigate fouling mechanisms mitigation approaches during DMF of municipal using crossflow system integrated with an optical coherence tomography (OCT) imaging system. During wastewater, it was...

A key step in the processing of ceramics is the consolidation of powders into engineered shapes. Colloidal processing uses solvents (usually water) and dispersants to break up powder agglomerates in suspension and thereby reduce the pore size in a consolidated compact. However, agglomeration and particle rearrangement leading to pore enlargement can still occur during drying. Therefore, it is b...
