Abstract—Today, nanosilica finds use in a variety of different areas such as biomedical, pharmaceutical, polymer, cosmetic, concrete, environmental and material applications. This work presented a laboratory studies on the preparation and extraction of nanosilica from sugarcane bagasse ash by precipitation method. The morphological analysis of sugarcane bagasse nanosilica (SCBN) was carrying out to be used as the additive in formulation of nanofiltration flat sheet membrane. Flat sheet membrane was fabricated via phase inversion technique. The effect of SCBN on the surface properties were observed and investigated. Membrane cross-section area and SCBN distribution were determined by scanning electron microscope (SEM). The analysis of SEM shows that the addition of different percentage of SCBN apparently changed the surface structure of the membrane particularly at sub layer and top layer. The performance of membranes was measured using flux pure water test and NaCl rejection test. The results indicate that the addition of 3% SCBN give the best rejection of 75.35 % and 42.65 L/m
2hr water flux.
