The oldest and most popular method of filtration is sand. Sand filters share two things in common: 1) When in the filtration mode, water always flows from top to bottom; 2) They all have some sort of lateral or underdrain with slots to hold back sand while allowing clean, filtered water to pass through.
Cleaning of the media, or sand, is accomplished through reversing the flow through the filter, to the "waste" line. This is known as backwashing.
