Sand filters are simple, effective and require very little attention. Water is routed through the sand-filled tank where the sand traps particles large and small. Eventually the dirt accumulates in the space between the sand particles, making it harder for the water to pass through. This causes the pressure in the tank to rise, which signals that the tank needs to be backwashed by reversing the water flow. Cleaning is done by backwashing so the back-wash water must be filtered.

Sand media filter working:

Backwash Working(manual backwash & automatic backwash)

When backwashing does occur, all filtering units do not simultaneously backwash. One unit will backwash for the specified time; then, the next unit in succession will backwash until all units have been cleaned. Also, there must always be at least two sand media filters in a system. During backwashing, a portion of the clean, filtered water from the other units is used to accomplish the backwashing process.
