Within the activities of scientific and cultural activity for the first semester of the Department of Chemical Engineering for the academic year 2017-2018, the lecturer Assist. Prof. Dr. Khaled Turki Rashed lecture entitled:
Polyvinyl hexafluoro PP membrane for use in direct contact membrane distillation system
POL (VINYLINDENE FLUORIDE- CO HEXANFLUOROPROYLENE) HOLLOW FIBER MEMBRANE FOR MEMBRAN DISTILLATION
Al Khwarizmi Hall in the presence of the Head of the Department of Chemical Engineering. Jamal Mouna Ali Al-Rubaie, assistants, branch heads, and a number of my teachers, students and students.
PolyThe polyphenols (fluoride, fluoride, hexaflopropiline), a hollow fiber membrane, was successfully synthesized by means of the phase reflection method. K-30 was used as an additive to form pores to improve morphology, structure and properties of the membrane. For membrane with good properties and be suitable for direct contact membrane distillation applications.
The morphological properties of all fibers were studied by means of electron microscopy scanning electron microscopy and also atomic force microscopy. Chakki was microvadvasive membrane joint and a slightly reduced contact angle was observed with increased pvp of (0% by weight to 9%). The volume of pores of hollow fiber increased significantly from 0.097 μm to 0.286 μm with addition (0 to 9) by weight. %. In the anesthetic solution, resulting in a marked increase in water flow from 4.2 to 22 kg / m2H at a feeding temperature of 80 ° C. And successfully modify formic acid on the membrane with 5 wt. % Proved from a contact angle that increased from 97.8 degrees to 109.9 degrees, increased fluid intake pressure from 2 to 2.4 bar. The best flow of interference to the membrane is modified with 9-watt. % About 23.9 kg / m 2 Buffer 80 ° C Feeding water feeding temperature. Optimization of operating parameters. Effect of process parameters, such as feeding temperature (40-80) ° C, feed flow rate (0.3-0.6 l / min), as well as feeding and concentration range from 3.5wt% to 5.0 wt. %.
