Filters capture particles through the mechanisms of impaction, interception and diffusion. Additionally, these filters are enhanced with electrostatically charged fibers to help trap particulates within the filter media. As particulate filters load up with the contaminant, they typically become more efficient; however, they also become harder to
Dilute acid has a significant effect on the removal of iron and aluminum, while the removal of titanium and chromium is carried out by acid leaching with concentrated sulfuric acid and aqua regia. Usually, the mixed acid composed of the above acids is used for acid leaching of impurity minerals. except.

The conditioned pulp is diluted with water to 25-30% solids and fed to a "Sub-A" Flotation Machine especially designed for handling the abrasive, slime free sand. Acid proof construction in most cases is necessary as the pulps may be corrosive from the presence of sulfuric acid. A pH of 2.5-3.0 is common.
Silica sulfuric acid (SiO 2-OSO 3 H 2, SSA), a solid acid, is prepared by soaking silica gel with sulfuric acid. SSA is used as a catalyst in different organic synthesis process. Silica sulfuric acid is considered as cheap, nonhazardous and easy to handle solid acid catalyst with high acidity.
Activated silica is a substance or material usually formed from the reaction of a dilute silicate solution with a dilute acid. Activated silica is frequently useful as a coagulation aid in water treatment.
