摘要：The aim of this study is to treat liquid waste from machining process using membrane technology. The cross-flow membranes has been performed for treating wastewater emulsion of oil derived from the automotive industry on the metal cutting section. The mechanism of ultrafiltration process is flow of small molecules pass through pore of membrane. The performance of the cellulose acetate hydrophilic membrane is determined by permeate and rejection flux. The operation of this two-stage ultrafiltration membrane involves a 12% composite cellulose acetate membrane (CA-12) in phase I and 15% (15%) cellulose acetate membrane (CA-15) in phase II with a 90 minute operating time with pressure of 3.5 bar. COD and surfactant rejection were resulted for both membrane with and without pretreatment process. In phase I,flux of CA-12 without pretreatment and with pretreatment were 67.03 L / m2.h and 81.05 L / m2.h respectively. The values of COD and surfactant rejection with pretreatment process are 86.57% and 86.35%, respectively. In phase II,the flux of CA-15 without and with pretreatment were 82.08 L / m2.h and 84.16 L / m2.h, respectively. Meanwhile,these values of COD and surfactant with pretreatment are 92.56% and 97.44 %. It concluded that CA-15 membrane with pre treatment produced better results in filtration the machining fluids due to the effect of nanoparticles that added to the membrane composition..
