“…The results (Table 5) showed a flux range of 9-32 L/m 2 •h and SR > 99%. These flux values are within the range of MD flux reported for PVDF membranes [27][28][29]. In general, no obvious trend could be extracted from the salt rejection data since they are considerably high for all samples.…”

Polyvinylidene fluoride (PVDF) is a popular polymer material for making membranes for several applications, including membrane distillation (MD), via the phase inversion process. Non-solvent-induced phase separation (NIPS) and vapor-induced phase separation (VIPS) are applied to achieve a porous PVDF membrane with low mass-transfer resistance and high contact angle (hydrophobicity). In this work, firstly, the impacts of several preparation parameters on membrane properties using VIPS and NIPS were studied. Then, the performance of the selected membrane was assessed in a lab-scale direct-contact MD (DCMD) unit. The parametric study shows that decreasing PVDF concentration while increasing both relative humidity (RH) and exposure time increased the contact angle and bubble-point pore size (BP). Those trends were investigated further by varying the casting thickness. At higher casting thicknesses and longer exposure time (up to 7.5 min), contact angle (CA) increased but BP significantly decreased. The latter showed a dominant trend leading to liquid entry pressure (LEP) increase with thickness.

The produced water, which could be a complex mixture of different organic and inorganic compounds (mostly salts, minerals and oils) is a major wastewater stream generated during oil and gas production processes. Due to increase oil and gas exploration and production, especially from unconventional resources like shale oil and gas reservoirs, the volume of this effluent production is increasing around the world and its discarding to the environment is one of the global concerns.

“…Membrane technology has provided a good opportunity and presents an interesting approach to study separation processes in numerous applications, such as in water and wastewater treatment, gas purification, food processing, pharmaceutical industries and bio separation areas [1]. In recent years, the application of UF membrane in protein separation is growing rapidly as it is easy to operate, incurs a low operating cost and does not involve any phase change.…”
