What is backwash in water filter?

Simply put, backwash filters will need to backwash once there is noticeable pressure loss through the filter – typically once every 1-2 weeks.
What are the advantages of a backwash filter?

Where does the backwash water go?
In unsewered regions, backwash water is to be discharged to a grassed, vegetated or garden area, or a stone-filled trench either open to the surface or underground (similar to a septic tank absorption field).
Why do I have to backwash so often?
Whenever the filter fills up with the dirt/debris it reduces the flow of water to your pool. Low flow = poor circulation which will lead to algae in the pool. Bottom line, the filter must be backwashed on a regular basis to ensure that your pool water is clear.
Do all pool filters need to be backwashed?

What’s the difference between rinse and backwash?
Rinse runs water in the same direction that normal filtering does. Backwash runs it through the sand in the opposite direction. Rinse is to clear any dirt out of the clean side of the sand before you start sending it back to the pool.
How long do you rinse after backwash?
Rinse the filter for about 1 to 2 minutes or until the water in the sight glass is clear. NOTE: Any electric heater must be off.
Why does sand come out when I backwash?
Your pump may be too large or the sand level too high in the filter. When the filter is backwashing the water flow can cause the sand to rise high enough and overflow into the standpipe, which will allow the sand back into the pool.
