Ionic silica is much smaller sized than colloidal silica and due to this, mechanical removal techniques such as flocculation, clarifiion, filtration and flotation are not an effective removal process. Technologies that allow removing silica are brackish or tap water reverse osmosis, Electrodeionization, Mixed Bed Deionizers or Ion Exchange.
· Due to its pyrogenic manufacturing process by combustion of silicon tetrachloride in an oxygenhydrogen flame, fumed silica offers a variety of fascinating properties. It consists of finely dispersed amorphous silicon dioxide and its surface is covered by highly reactive silanol groups which are available for chemical reactions.
· To design a silica gel dehydration system, it is necessary to select the duration of the onstream time per tower before switching towers. This is usually 8 to 12 hours for fully watersaturated gas. After establishing the cycle time and the amount of water to be removed from the gas during one cycle, the bulk volume of desiccant can be estimated.
