How does a layer
Filter work?
A dual or multi-media filter typically contains two or more layers of filter media consisting of anthracite charcoal, sand, garnet, etc., plus a supporting (non-filtering) support layer at the bottom. The larger (but lighter) anthracite is on top and the heavier (but smaller) garnet remains at the bottom. The layers of filter media allow the largest dirt particles to be removed from the top of the media bed, with the smaller dirt particles being retained further and further down in the media. This allows the entire filling to act as a filter, allowing much longer filter run times between back flushing and more efficient particle removal.
Water flows through several layers of different grain size from the top to the bottom. During this process, sediments/contaminants are retained in the filter bed.
