There are a number of filtration systems that can be used with swimming pools. The most common types include sand filters, cartridge filters and Diatomaceous earth filters. Among the different filters that homeowners of an Orange swimming pool use, the sand filter is the most common.
San filters are the cheapest filters that are used for swimming pools. This filter works in a very similar fashion to an espresso machine. The swimming pool water is pushed through a bed of sand and removed through a set of lateral tubes at the bottom. Cleaning sand filters are also relatively easy, all that homeowners need to do is to ?backwash? the filter. This is the process by which water is run in the reverse direction of the filter.
The advantage of a sand filter for a swimming pool is that homeowners can rinse the filter and repack the sand into the filter. This needs to be done manually every few weeks. Sand filters are the cheapest filters that can be used in pools. A disadvantage to them is that they are also the least effective. These filters allow smaller particles to flow back into the pool.
