ND Filters: Mounted, AR Coated for 650 - 1050 nm.
The Rapid Sand Filter (RSF) water treatment equipment differs from the Slow Sand Filter water treatment equipment in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using back washing. The mechanism of particle removal also differs. Rapid sand Water filter does not use biological filtration and depends primarily on.
In general however, rapid sand filters are usually fully automated, complex and costly, forming part of a wider treatment process in industrialized countries. They are not known to be suitable for household-level use, as is the case with versions of the slow sand filter, for example the intermittently operated slow sand filter (or IOSFF). For.
The main benefit of a sand filter is the simple system which, in many cases, can be used to obtain considerable yields. A sand filter can be placed in various phases of water management - as a pre-treatment, as side-stream filtration and as a polishing filter. A sand filter often provides an effluent with potential for re-use. However, chemicals sometimes need to be added to improve the yield.

The major parts of a gravity rapid sand filter are: Chamber: filter tank or filter box; Filter media (sand) Gravel support; Under drain system; Wash water troughs The filter chamber is usually made out of reinforced concrete, filled with sand and gravel to the height of 1.5-2 metres. The water is supplied to the top of the sand-bed and filtered.
The rapid sand filter or rapid gravity filter is a type of filter used in water purification and is commonly used in municipal drinking water facilities as part of a multiple-stage treatment system. Rapid sand filters were first developed in the 1890s, and improved designs were developed by the 1920s. The first modern rapid sand filtration plant was designed and built by George W. Fuller in.
Neutral Density Filters, ND filters, reduce the amount of light reaching the camera lens meaning the camera can perform with a higher aperture to produce a result far closer to how it appears to the eye.
