Sand or anthracite filter media used in a wide range of bed depths and particle sizes have produced satisfactory results Selection of the bed depth or particle size to be use in any particular filter is the responsibility of the designer and should be done with careful consideration of raw water conditions and plant pretreatment facilities

Raw water access into sand filter by water feeding pump and is channeled to filter top and then falls on a sand bed With the pressure and gravity the water will permeate down through the sand bed Filtered water then exits through laterals at filter bottom and the trapped dirt on the sand bed is removed via periodic backwashing and

Mar 08 2021 Filtration is a process in which the water in the pool is lifted by the circulating pump intercepted by Diatomite on the surface of the filter element and then re entered into the pool The filter strength of candle diatomite is designed as 354 m3 H m2

In Ultra Filtration Plant raw water is first entered into Sand Filter its the 1st stage filter which removes physical particles up to 20 micron size amp turbidity from water The Sand Filter is a very basic component of Ultra Filtration Plant it has multilayered beds of sand media like Gravel Quartz

Raw water is passed through the pressure sand filter the filter media Fine quartz sand is supported on gravel amp pebbles bed of progressively larger sizes During the filtration cycle the filter bed retains the dirt and suspended particles from the water and accumulates within the filter bed Clear water can be collected from the outlet of

Quartz sand silica sand anthracite coal garnet magnetite and other materials may be used as filtration media Silica sand and anthracite are the most commonly used types When silica is not suitable eg in filters following a hot process softener where the treated water is intended for boiler feed anthracite is usually used
