Naturally, silica present in water feed in the range of 1-100 ppm. It is existed as silicic acid (H2SiO3) which is a weak acid and dissociated at or below neutral pH [1,2]. The presence of silicic acid lead to form silica colloidal in water at neutral pH. But when pH exceeds the neutral, silicic can be dissociated and form silicate anion (SiO3 2-), which can react with positive ions like calcium, magnesium, iron, manganese and aluminum to form insoluble silicates .
