• Description


In single-media filters, the smallest particle media rise to the top due to the difference in density. Since the smallest media is at the top, the filtration process usually takes place in the first few centimeters of the media. For this reason, the pressure loss increases rapidly and speeds up the media entering the backwash.

Ideally, the largest particle media should be at the top and the particle or media size should decrease towards the flow of water. In this way, the large particles in the water are in the top layer, the middle particles are in the middle part of the media and the smallest particles are in the bottom layer, increasing the media’s solids holding capacity. This way, less backwashing will be required

Since Garnet media has a specific density of 4, it is the heaviest media material and can filter up to 10-20 microns. Filter sand or Turbidex mineral is used as the middle layer, and anthracite media is used as the top layer mineral with the least density and the largest particle size.

Multi-layer filters (multi – media) can be used in both water and wastewater. Although the amount of media can be changed according to the characteristics of the raw water and the quality of the treated water, 55% of the filter bed is composed of low density minerals, 30% is medium density and 15% is high density media.

If heavier filtration minerals are to be used, numbered 8 Garnet serves as an ideal support bed.
