Abstract
Polysulfone (PSf) polymer membranes have been broadly used in water refinement, and nanospeaches have been introduced to the polymer medium to improve its hydrophilicity besides performance. Polysulfone was produced for this work by dissolving polysulfone beads in N, N-dimethylformamide (DMF). The addition of nanosphere particles, such as mesoporous silica MSNs ” " ~ " ”500nm, to the membrane material matrix significantly improved water penetrability and dye elimination. For the fabricated membranes, the dry/wet stage conversion process was used. The effect of various MSNS concentrations (2–8% wt.%) in the existence of povidone (PVP) acting as a pore generating agent on behavior of the PSF-UF membrane was examined. The rejection of Methylene blue (MB) dye rapidly rose as the MSNs content climbed until it reached 6 wt. percent.Scanning electron technique was used to evaluate morphological features of UF-produced membranes PS/PVP/SiO2. They showed a significant degree of (MB) rejection of 84.7 percent, as well as a 6 percent rise in MSNs concentration. Furthermore, as MSNs content was enlarged to 6 wt.%, the membrane penetrability decreased from 429.2 L/m2.h for PS/PVP to 136 L/m2.h for PS/PVP/SiO2 (6%) membrane. On the feed side, only water was accepted to pass through hydrophilic UF fabricated barriers, which improved the quality of the water stream on the permeate section, making the fabricated membranes suitable for industrial wastewater treatment. The use of Polyvinylpyrrolidone as an adjuvant to the membranes studied improved their efficiency.
