Today, numerous businesses produce significant amounts of wastewater that is greasy. Separating the stable emulsified oil particles from water is the fundamental difficulty in treating oily wastewater. Generally speaking, polymeric membranes are essential in these procedures due to how simple and inexpensive modern separation processing is, as well as how flexible they are. The phase inversion method utilized in this study to create a poly vinyl alcohol (PVC) membrane is demonstrated. In order to increase both permeation flow and fouling resistance, PVC has been modified by the addition of polymeric additives like polyvinylpyrrolidone (PVP). Additionally, in this paper, we compare lab chemical membrane and commercial chemical membrane on the basis of their fluxes, rejection, and characterization. The enhanced PVC/PVP membranes were characterized and evaluated using mechanical strength, porosity, scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR), and water contact angle measurement. The membranes were subsequently tested at a lab size in a cross-flow system with synthetic greasy wastewater as the input.
