Laundry waste pollution can be handled through the development of filtration with the Gravity Driven Membrane (GDM) method which is designed to follow the criteria of the unloading module design, low polarization control, cost-effective, separation process using thrust in the form of a strong pressure difference. This type of research was an experiment. This study aimed to determine the performance of laundry waste filtration at ultra low pressure using clean water permeability and detergent solution as standardization. GDM filtration performance was tested by measuring permeability at a pressure of 1-10 kPa with two repetitions and long-term filtration for 35 days at a pressure of 6 kPa, the sample was replaced every 7 days without membrane washing. The results showed that as the pressure increases and the filtration time increases, the permeability of laundry waste decreases, this phenomenon is caused by compaction and clogging of the membrane pores (fouling). Permeability decreases from 1 kPa to 10 kPa pressure, the same applies to repetition. Long-term filtration permeability decreased significantly from the first day to the eighth day of filtration respectively 707.9 , 151.7, 115.8, 104.4, 97.5, 107.1, 102.1 and 103. 0 L/m2.hour.bar. On the 9th to 35th day the decrease was stable, this was caused by fouling on the membrane which resulted in the membrane becoming more compact and saturated. GDM filtration can take place for 35 days without washing the membrane with a permeability from the first day of 707.9 and the 35th day of 5.5 L/m2.hour.bar. The best performance of this filtration process lasts until the 9th day
