The composite filter aid may comprise a silicate substrate and a precipitated magnesium silicate with a SiO 2 : MgO molar ratio of greater than about 1.0: 1. Method of manufacturing a composite filter aids may include the step of forming a composite filter aids precipitated magnesium silicate on the stage, the silicate substrate to provide a silicate substrate, SiO 2 of the magnesium silicate molar ratio of MgO is from about 1.0: 1 . The filtration method of the non-aqueous liquid may include providing a non-aqueous liquid for filtration and filtering the non-aqueous liquid through the composite filter aid. |
