HYDRO-ANTHRACITE MEDIA is produced by the grinding and sieving of natural anthracite previously put through heat treatment.
The structure characterizes the very tough grains of this filter material.
HYDRO-ANTHRACITE conforms to the purity conditions defined in the regulations concerning mineral products used in water treatment for human consumption. HYDRO-ANTHRACITE is an economical, reliable system requiring minimized maintenance thanks to the stability of the grains.
HYDRO-ANTHRACITE is essentially used in the upper layers of dual-layer filters.
It can also be used as a single layer filter to deal with certain specific water treatment issues.

The use of HYDRO-ANTHRACITE MEDIA in filters with several layers results in:

• improved filtration efficiency by the increased solid matter retention capacity of the filter bed in the course of in-depth filtration.
• improved and more stable quality of the filtering process by the use of a fine particle size filtering material in the lower layer.

• economic advantage because of the longer filtration lifecycle, reduced washing water consumption, without requiring a larger plant.
HYDRO-ANTHRACITE is used in open or closed filters for:

• well, spring or surface water filtration when the water contains suspended solids.
• filtration of water containing a large amount of suspended matter for iron removal or biological or catalytic manganese removal.
• flocculation water filtration with or without flocculation additive (downstream of a decanter or flotation or with flocculation on a filter).
• decarbonized water filtration directly downstream of a reactor.
• industrial water (cooling or process) filtration.
• swimming pool water filtration: take into consideration the possible chlorine removal effect up to fouling of the adsorbent surface.
• multilayers of chemically active filtering materials to protect their contact surfaces.
• filtration of physically and/or biologically pretreated residual water.
• increased safety regarding piercing because the lifecycle through piercing is greater than that controlled by a head loss.
