Abstract
Large volumes of oily wastewater are now being produced from a variety of sources. Since stable emulsified oil particles are generally easy to process using advanced separation techniques, inexpensive, and have high degree of flexibility, this is the most difficult part of treating oily wastewater, polymeric membranes are important in these processes. Many types of additives are added to a based polymer to increase it is hydrophilicity and increase it is properties as enhancing pure water flux (PWF). This research demonstrates the phase inversion method using N,N- dimethylformamide (DMF) to build modified PVC membrane. Modification of PVC has been done to increase both permeation flux and fouling resistance by adding polymeric additives like polyvinylpyrrolidone (PVP) since the concentration of oil is reduced by 93.75 % and 92.806 % for laboratory chemical membrane (ML) and commercial chemical membrane (MC) used as known as rejection percentage, also we study the factors affecting separation process and the most two important factors studied were concentration of emulsion (1000, 2000, 4000 ppm) and different temperature of feed stock at (10o C & 80o C). Study the coating of membrane with organic or inorganic compounds as TA, PVP and Feш since the flux for lab chemical membrane increased by 57.42% and rejection of oil increased by 5.89% but for commercial chemical membrane the flux increased by 55.56 % and rejection of oil increased by 6.445 %. In this research also we compare between lab chemical membrane and commercial chemical membrane on the hand of their fluxes, rejection and characterization. The mechanical strength, porosity, scanning electron microscopy (SEM), Fourier transform infrared (FTIR) and water contact angle measurement were used to characterize and assess the improved PVC/PVP membranes. Finally, the membranes were evaluated in a lab scale cross flow system with synthetic oily waste-water as feed.
