HOW A HIGH RATE MEDIA
FILTER WORKS
The filter pump draws water from the pool and forces it under pressure into the multi-function innoValve where
it is directed into the top of the filter tank via an overdrain diffuser. The water then flows down through the
media bed, into the underdrain and back to the pool.
The action of the water containing suspended particles passing through the filter bed causes the larger
particles to be trapped and retained by the Diamond Kleen. Some of the very small particles may, however, pass
completely through the filter and return to the pool, but in the process will have gained an electrostatic charge
due to their high velocity over the media. This charge causes these particles to be attracted together to form
clusters which are then large enough to be trapped by the Diamond Kleen on their next pass through the filter.
This is a normal characteristic of all high rate media filters.
As the quantity of suspended particles trapped in the media bed increases, the passage of water becomes
progressively restricted, but this also results in an improvement in filtration fineness. However when this
restriction to flow becomes excessive (as indicated by the rise in gauge pressure) the filter must be cleaned to
restore a normal flow of water.
Cleaning is achieved by reversing the flow of water so it flows upwards through the media bed causing the
individual grains of filter media to become buoyant and allow the bed to expand and release the trapped dirt
particles which are then flushed out of the filter to the waste drain. This process is called BACKWASHING.
