US Water Sand-Sentry Sand Eliminator

The Sand-Sentry is the absolute best method to separate and settle out sand, shale, and oxidized organics found in some water supplies. This is accomplished by running the water through an internal swirl chamber then into a diverting plate. This will allow the heavier particles to settle to the bottom of the tank for blow down at a later time. The Sand-Sentry acts as a hydrocyclone, which is a static device that applies centrifugal force to a flowing liquid mixture so as to promote the separation of heavy and light components. This is a classic hydrocyclone, in that it is a closed vessel designed to convert incoming liquid velocity into rotary motion. It also then separates the solids from the water stream by allowing them to settle to the bottom of the tank. After the Sand-Sentry it is recommended that a 5-Micron Magna Filter be utilized which provides a physical barrier to any sand, above 5-microns. In some extreme cases, a second filter with a 1-Micron filter cartridge may be necessary, depending upon how fine the sand is.
