Sand Filters: How its work and what is the best

Sand filters are the oldest form of filtration for a swimming pool. These consist of a large spherical-shaped globe. It contains silica sand and may be referred to as simply ‘filter sand’. As water flows into the filter it passes through the sand. 

The dirt and other particles go trapping in the sand. And it is allowing clean filtered water to return back into the pool. Sand filters can remove particles that may be under 20 microns, no matter. The filter sand can last 5-10 years between changes giving you a very cheap filtration system.

Backwashing a sand filter system is part of the regular maintenance of the system. It is because of becoming trapped in the sand. It restricts the water from flowing back to the pool. 

Your pressure gauge will start to increase as the filter sand clogs up with dirt and debris. This is your signal to perform a backwash. Backwashing will send out the dirty water through another port on the valve usually labeled “waste”.
