摘要： A cationic composite filter aid may include a silicate substrate, a silica precipitated on the silicate substrate, and a cationic surface modification of the precipitated silica. A method for making a cationic composite filter aid may include providing a silicate substrate, precipitating a silica onto the silicate substrate to form a composite filter aid, and cationically modifying the precipitated silica to form a cationic composite filter aid. A method for filtering a liquid may include providing a liquid for filtering and filtering the liquid through a cationically modified composite filter aid. The cationically modified composite filter aid may include a silicate substrate, a precipitated silica, and a cationic surface modification of the precipitated silica.

摘要： A composite filter aid may include a silicate substrate and a precipitated magnesium silicate having a mole ratio of SiO2:MgO greater than about 1.0:1. A method for making a composite filter aid may include providing a silicate substrate, precipitating a magnesium silicate onto the silicate substrate to form a composite filter aid, wherein the mole ratio of SiO2:MgO of the magnesium silicate is greater than about 1.0:1. A method for filtering a non-aqueous liquid may include providing a non-aqueous liquid for filtering and filtering the non-aqueous liquid through a composite filter aid.
