| dc.description.abstract | The commercial ultrafiltration PVDF tubular membranes (FP100) were applied for separation of effluents generated during car washing. Using a 50-75% water recovery coefficient allowed to obtain over 60% rejection of COD, and obtain the high-purity permeate (0.3 NTU). However, significant flux decline was caused by a severe membrane fouling. The tubular polyvinylidenefluoride membranes of 100 kDa were obtained from PCI (Poland). The tube inner diameter was 12.5 mm. Wastewater generated from a manual car wash was used for ultrafiltration tests. Wastewater sample collected from the settling tank with a turbidity of 215 NTU contained over 300 mg/L of suspended solids. In addition to the pollutants removed from the cars, it contained surfactants used for washing (120 mg/L), and the determined COD value was 2200 mg O2/L. The transmembrane pressure (TMP) was maintained at 0.05-0.3 MPa, and the feed flow velocity over the membrane was equal to 1 m/s. After completion of UF process, the membranes were rinsed with deionised water and cleaned with alkaline (pH>11) and acid solutions. | en |
