Sand is the oldest and most popular method of filtration. All sand filters share two things in common:
- When in the filtration mode, water flows from top to bottom
- They all have some sort of lateral or underdrain with slots to hold back sand while allowing clean, filtered water to pass through.
High-rate sand filters use a special filter sand, normally .45 to .55 mm (also known as pool grade #20 silica sand), because it has sharp edges that separate particles, allowing filtration to take place.
