Gravel Filtration – Process Description
FILTRATION PROCESS
Water enters the filter via the inlet and spreads equally on the media.
In the filter, there is a layer of 40 cm Quartz Sand with an effective size of 0.6mm - 1.2mm.
The water passes through this media.
The media inside the filter has to be 40 cm deep, no less, but also not more than this.
The depth of the media is one of the most critical parameters of filtration quality. As result of the 40 cm depth and wide surface area of the media layer, dirt particles and organic materials are trapped on the media surface. Most of the dirt will be stopped on the upper surface. Other small particles and floating materials will be trapped on the media particles surface at 40cm depth.
