Summary:A process for preparing precipitated silica, in which a silicate is reacted with an acidifying agent in order to obtain a suspension of precipitated silica (S1), followed by: a separation step in order to obtain a cake, a cake-disintegration step in order to obtain a suspension of precipitated silica (S2), and a suspension drying step. According to the invention, a membrane concentration step is performed between the disintegration step and the drying step.
