Sand

Sand Filters. There are two types of sand filters: sand filters and sand separators. The sand filter uses relatively coarse sand and other granular media to remove particles and impurities. The sand separators use centrifugal force to separate particles out of the water. The separated material drops into a reservoir where it can be removed. They are not true filters, since no physical barrier separates out the particles, but they are often used upstream of a filter to remove the bulk of the contaminant, where the filter does the final cleaning.
