ABOVE GROUND SAND FILTER SYSTEMS
The oldest and most popular method of filtration. Sand filters work in two ways:
In filtration mode, water always flows from the top to bottom. They have some sort of lateral or under drain with slots to hold back sand while allowing clean, filtered water to pass through.
High-rate sand filters use special sand, (also known as pool grade #20 silica sand), because it has sharp edges that serve to separate particles, allowing filtration to take place. They operate on the basis of "depth" filtration; dirt is driven through the sand bed and trap debris in the minuet spaces between the particles of sand. Initially, a clean sand bed will remove large particles, and then, as the bed starts to load up, it will remove finer particles.
Cleaning of the media, or sand bed, is accomplished through reversing the flow through the filter, backwashing to the "waste" line.
