| description |
The treatment of oily wastewater is a challenging and complex task. Their efficiency in removing oil was evaluated in efforts to reach two objectives: increasing permeate flux as well as maximizing oil removal. The surface features of the constructed membranes were examined with a FESEM device, and atomic force microscopy (AFM) was employed to investigate the topography of the substrate surfaces. The water contact angle and wettability were determined using the Contact Angle Measuring Instrument; Porosity was evaluated through a gravimetric method, while the average diameter of the nanofibers was measured with ImageJ software. It was observed that higher concentrations of PVDF/DMF precursor solutions led to an increased average diameter of the nanofibers within the membranes, which is between 0.175 and 0.4 µm. Furthermore, the membranes surfaced exhibited an increase in average surface roughness (Ra) from 0.171 µm to 0.279 µm, while the contact angle increased from 81° to 135°. This demonstrates that the 14% PVDF-based nanofiber membrane had hydrophobic properties. These variations positively affected the membrane's efficiency, as demonstrated by the increase in permeate flux and oil rejection rate, which rose from 58 to 136 LMH and from 85.5 to 96%, respectively, without applying any pressure.
