Desiccant
A desiccant is a hygroscopic material used for maintaining dryness. For manufacturers, the purpose of silica gel is to be used as a desiccant. Silica gel also serves to keep the relative humidity inside a system of satellite transmission waveguide as low as possible. In compressed air systems of any industry, silica gel is also used to dry the air. Where a bed of silica gel beads is made for the air from the compressor discharge to flow through it. The silica gel beads are used for adsorbing the amount of moisture present in the air and preventing it from damaging at the point of use of the compressed air due to condensation. A similar kind of system is used for drying the compressed air on railway locomotives.
Water filtration
Silica gel has water absorption properties because of this property it is used in domestic water filters. Some minerals that are dissolved in water can be absorbed by the surface structure of silica gel. Because of the lack of regulations for products of the filtrations of domestic water, no studies give validation to the manufacturer claims regarding the effectiveness of the filtration system of sorbent silica gel.
