Sand has for a long time been used to clean as well as purify the water. 4 grades of sand are majorly used for water filtration all over the world. Today, the provision of good quality potable water is taken for granted in much of the developed world. So, how exactly does it work? Natural sand has a sub-angular to the rounded shape, that does makes them ideal filtration media to be able to capture the suspended solids in the water. As a result of the high silica content, sand is durable and hard-wearing, which allows it to graded precisely so as to facilitate efficient filtering. Sand gets to be laid on top of the supporting layer of the gravel within the filter vessel. Incoming water enters the filter and migrates through silica sand, hence successfully removing any solid or even debris from the water. As a result of its uniqueness in terms of its properties, the silica sand is usually used for water filtration in a wide variety of applications that do include swimming as well as leisure, paper processing, power generation, chemical processing, and portable as well as wastewater treatment. In the market, there are various types that are available. The pressure filters are operated with a feed pressure of two to five bar and usually used in leisure applications. Feedwater does enter and passes through the bed of sand. The majority of particulate solids are usually captured high up in the filter beds, this kind of filter is able to capture even the small particles. The buildup of the particulate solids does cause an increase in pressure loss across the bed for a certain given flow rate. When this pressure loss or the flow rate is not the acceptable bed is back washed to be able to remove accumulated particles.
