Stability and deformation of oil droplets during microfiltration on a slotted pore membrane

Prediction of size distribution of crude oil drops in the permeate using a slotted pore membrane

“…Experimental tests were carried out with a vibrating microfiltration rig provided by micro-pore technologies UK for schematic view of the rig see Figure 3 of [18]. Experimental set-up for filtration without membrane oscillating is provided in Figure 3 of [15]. Full details about the used materials and experimental procedure are provided in [15,18].…”

“…Static force ( x c F ) is the force responsible for the rejection of drops through the membrane without shear applied to the surface of the membrane and can be expressed as follows: [15], …”

“…Extrapolating 100% cut-off to the origin of rejection graphs gives a straight line that is referred as 'Linear fit' and can be used for predicting rejection of drops below 100% cut-off [15]. 'Linear fit' provide the idea of fraction of oil rejected and passed through the membrane.…”

“…Pore structure design has attracted researchers and circular pore membranes with surface filtration filters are found efficient in oil/water separation [13]. Slotted pore membranes were found less foulent and higher permeate flux and better separation of filtering material were achieved specially with deforming oil drops as compared to circular pore membranes [14][15][16][17][18][19].…”
