Examination of Silica Removal with Solids Recycle for Reverse Osmosis Pretreatment
… can include size, charge, or solubility. Silica (SiO2) is difficult to remove during water treatment because it can exist in ground and surface waters as various dissolved and particulate species, all of which are defined by different properties. Silica speciation is dependent on variables …

The study of pretreatment options for composite fouling of reverse osmosis membranes used in water treatment and production
… are calcium carbonate, calcium sulphate and silica. However, silica fouling is the recovery limiting factor in RO system. Silica chemistry is complex and its degree of fouling strongly depends on the silica solubility and its polymerization under different operating conditions of RO process. …

Nanostructured Porous High Surface Area Ceramics for Catalytic Applications
… ceramic materials. Ordered mesoporous silica SBA-15 was found to be useful as a hard template for the nanocasting of silicon carbide and allowed the preparation of high temperature stable mesoporous silicon carbide ceramics. Chemical vapor infiltration of SBA-15 with …
