Reverse osmosis (RO) is one major water treatment process used to filter out the water pollution due to the Tsunami disaster in Pandeglang. This technology is applied where highly purified water is essential, including sea/groundwater desalination, boiler feed water filtering, product rinsing, laboratory testing, and biotechnology. However, RO requires advanced research to ascertain the method and optimum pressure of the multi-pass system needed to produce clean water through a membrane with a long saturation time. Therefore, this study employs RO multi-pass by varying pressure 6-3, 6-4, and 7-4 on the first and second stage to observe the effects of decreasing flux and TDS enhancement for 72 hours in Tanjung Lame village. The results showed more performance in producing potable water at pressure P 1 = 6 bar/P 2 = 3 bar compared to P 1 = 6/P 2 = 3, and P 1 = 7/P 2 = 4. Moreover, the total dissolved solids (TDS) known to satisfy clean water provision was estimated at 20 ppm, after the permeate in the first stage is used as feedstock in the second. Furthermore, applying P 1 = 6 bar and P 2 = 3 bar for the first and second stage produced the membrane saturation time in hours ranging between 72-80 and 72-131, respectively.
