The composite filter aid may include a silicate substrate and precipitated magnesium silicate having a SiO 2 : MgO molar ratio greater than about 1.0: 1. The method of manufacturing a composite filter aid may include providing a silicate substrate, sedimenting magnesium silicate on the silicate substrate to form a composite filter aid, and the molar ratio of SiO 2 : MgO of the magnesium silicate is about 1.0: 1. Is over. A method of filtering a non-aqueous liquid can include providing a non-aqueous liquid for filtration and filtering the non-aqueous liquid through a composite filter aid. |
