Filtration for Non Filtration Specialists:
Pools, spas and ponds require water to be filtered (and as appropriate disinfected) to provide safe places for recreation and livestock. Poor maintenance can lead to clogged filters which can increase the risk of water borne infection.

Typically water filters contain clean closely graded silica sand often carried on a bed of filter support gravel. A pressure fed sand filter or "high rate" sand filter, which is generally located immediately after the pump will typically remove particles down to 10 microns in size (ten thousands of a millimetre).

Water is pumped under pressure into the top of the filter and leaves at the bottom. On the way through suspended dirt and debris in the water is trapped by the particles of sand.

Sand filters need to be cleaned regularly. By re-directing water back up through the sand bed and out to waste, accumulated dirt is flushed out, this is process is called back washing. Sand filters come with a valve known as a multiport valve to change the direction of water flow and to facilitate this process.

Sand media needs changing every three to five years, however, also be aware of a phenomena known as chanelling. This is where water cuts channels in the sand leading to a loss in filter efficiency an again will require the media to be replaced.
